Angina
Red Flags — act before continuing history
| Red flag | Why dangerous | Action |
|---|---|---|
| Chest pain present right now at rest, or pain lasting >20 minutes not relieved by GTN | ACS (NSTEMI/STEMI) until proven otherwise. Every minute of sustained coronary occlusion = loss of myocardium. Time-to-balloon (PCI) is the dominant determinant of outcome. Do not continue routine history — obtain ECG immediately and call 999 if ST elevation. | ECG immediately; 999 if ST elevation |
| ST elevation on resting ECG with chest pain symptoms | STEMI — complete coronary occlusion; myocardium dying. Primary PCI target door-to-balloon <120 minutes. Every 30 minutes delay increases mortality by 7.5%. Call 999 directly to cathlab pathway, not ambulatory referral. | 999 immediately — STEMI pathway |
| Crescendo pattern: same activity causing progressively worse symptoms, or same pain now on less exertion than 2 weeks ago | Unstable angina / NSTEMI — plaque destabilisation with partial thrombosis. High early MI risk (3–15% within 30 days without treatment). Negative troponin does not exclude unstable angina. Requires same-day assessment and antiplatelet loading. | Same-day chest pain assessment unit |
| Tearing chest pain radiating to the back or interscapular region | Aortic dissection — mimics ACS and is catastrophically worsened by antiplatelets and thrombolytics. Type A (ascending) = surgical emergency; 1–2% mortality per hour untreated. BP asymmetry between arms and pulse asymmetry are the key examination findings. CT aorta is the diagnostic test. | 999 — do NOT give aspirin before aortic dissection excluded |
| Exertional chest pain + exertional syncope or near-syncope | Aortic stenosis (classic triad: angina + syncope + dyspnoea on exertion). Severe aortic stenosis presents with sudden cardiac death. Urgent echocardiography — management is surgical/TAVI, not antianginal drugs. Beta-blockers and vasodilators may worsen severe AS. | Same-week cardiology + urgent echo |
| Haemodynamic instability: hypotension (SBP <90), tachycardia (>120 bpm), diaphoresis, acute pulmonary oedema with chest pain | Cardiogenic shock from acute MI with large territory ischaemia or mechanical complication (acute MR, VSD). Mortality without immediate PCI and haemodynamic support is >50%. This is the highest-mortality acute cardiac presentation. | 999 — cardiogenic shock pathway |
Safeguarding Considerations — Consider in Every Consultation
🏠 Domestic Abuse & Trauma-Induced Chest Pain
- Chest pain from direct thoracic trauma (assault, rib fractures, sternal injury) may mimic or coexist with cardiac ischaemia — perform chest examination systematically
- Psychological trauma and PTSD cause catecholamine surges that can trigger Takotsubo syndrome (stress cardiomyopathy) — mimics acute MI with ECG changes and troponin rise, but normal coronaries; predominantly in post-menopausal women after acute emotional stressor
- Chronic stress from DV elevates resting HR and BP — both lower the ischaemic threshold and worsen angina in patients with known coronary disease
- A patient who cannot take their angina medications reliably because a controlling partner manages household finances or monitors their behaviour is experiencing medical neglect within abuse
👴 Older Adults — Atypical Presentation & Neglect
- Angina in older adults, women, and people with DM frequently presents atypically: jaw pain, fatigue, indigestion, breathlessness, or shoulder pain without chest pain — these presentations are systematically under-referred and underdiagnosed
- Cognitive impairment prevents accurate symptom reporting — carer-observed symptoms (patient clutching chest, stopping suddenly, appearing distressed on exertion) may be the only history available
- Isolated older adults may delay presentation significantly — angina of weeks' duration before attending a GP is common and represents missed opportunity for earlier intervention
- Financial exploitation in post-MI patients: vulnerability during recovery, dependency on carers, and disrupted cognitive function all increase exploitation risk
🧒 Young Adults — Substance Use & Undiagnosed Conditions
- Cocaine, amphetamines, and methamphetamine cause coronary vasospasm and ACS in young adults — urine toxicology in any unexplained ACS in under-45s; specific management (CCB not BB for cocaine-related vasospasm)
- Familial hypercholesterolaemia (FH): premature severe CAD in young adults with no traditional risk factors; strongly positive family history; xanthomata; tendon xanthomata; cascade screening of first-degree relatives mandatory
- Young women with exertional chest pain: consider vasospastic angina, microvascular angina, and peripartum cardiomyopathy in recent postpartum women
💊 Medication Safety & Deliberate Omission
- Deliberate omission of antiplatelet therapy (aspirin, clopidogrel) or statin by a controlling partner can precipitate in-stent thrombosis or ACS in a post-MI patient — if adherence is poor, explore who manages the medication
- GTN misuse or over-use: tachyphylaxis from continuous long-acting nitrate use; tolerance develops within 24 hours — nitrate-free period required. Patients using GTN spray multiple times daily may be masking escalating instability
- Beta-blocker sudden discontinuation can cause rebound tachycardia and unstable angina / precipitation of ACS — always taper, never stop abruptly
- Post-discharge non-adherence to dual antiplatelet after PCI within the first year = major stent thrombosis risk; explore barriers to adherence
💀 Fear of MI and Premature Death
The dominant psychosocial experience of new angina is anticipatory grief — the patient has crossed a threshold from "healthy" to "heart patient" and is processing the implications of that identity shift. For patients with a parent who had a young MI, this is extraordinarily concrete: Michael is 57, his father had a MI at 58. The consultation happens in the shadow of that anniversary.
"I can see from your family history that this must feel very close to home. I want to be direct about what we know: your father's story doesn't have to be your story. The treatments we have today are fundamentally different from what was available then. Let's talk about what we're going to do to change your trajectory."Do not offer false reassurance. Offer honest, evidence-based reframing. "We cannot guarantee you will not have a heart attack, but we can dramatically reduce the probability." The patient deserves this honesty more than they need comfort.
💼 Work, Stress, and the Angina–Anxiety Spiral
Occupational stress is both a risk factor for and a consequence of angina. Anxiety lowers the ischaemic threshold — a patient who is anxious about their chest will have a lower CCS threshold because stress increases HR and BP. Many patients, particularly men, attribute chest symptoms to stress as a socially acceptable alternative to the cardiac explanation they fear. This attribution prevents timely investigation.
"You mentioned work stress might be contributing — and you're right that it can. But stress as a cause and this being a heart problem are not mutually exclusive. The investigations will tell us what's happening in the arteries, and then we can address both the physical and the work pressures."Validate the work stress attribution without accepting it as the diagnosis. PHQ-9 and GAD-7 at every review. NHS Talking Therapies referral. Occupational health review for reasonable adjustments.
❤️ Sexual Activity and Intimacy
Sexual activity is an angina trigger that is almost never raised by patients and rarely asked about by GPs — yet it is one of the most important psychosocial consequences of angina for relationships, self-image, and adherence. The fear of triggering chest pain during sex causes avoidance, relationship strain, and hidden anxiety. PDE5 inhibitors for erectile dysfunction + nitrates = life-threatening combination that cannot be allowed to pass undiscussed.
"This might feel like an unusual thing to raise, but it's important — has your angina affected your intimate life at all? Some people avoid physical activity including sex because of the chest discomfort. I also need to ask: are you taking any tablets for sexual function, like sildenafil or tadalafil? This is medically important because one of the treatments I want to give you cannot be combined with those tablets."GTN can be used prophylactically 5–10 minutes before sex in patients NOT on PDE5 inhibitors. Refer to urology or sexual health for alternative ED management if GTN is indicated and PDE5 inhibitor is being used. Document this conversation explicitly.
🚗 Driving, DVLA, and Occupation
Angina has specific DVLA implications. Group 1 (cars): patients may continue driving but must not drive during an episode of angina; must notify DVLA if angina occurs at rest or at the wheel; must declare on car insurance. Group 2 (HGV/bus/PCV): must notify DVLA; must be free from angina for at least 6 weeks before driving Group 2 vehicles; stricter ongoing requirements post-revascularisation.
"I need to tell you about what this means for driving. For everyday car driving, you can continue as long as the pain doesn't come on while you're driving. But you must not drive if you're having a chest pain episode. I'll also need to document that we've discussed this today."For Michael as an accountant (likely Group 1): stable angina does not prevent driving. But this must be documented at diagnosis. Group 2 drivers must notify DVLA and stop Group 2 driving until free from symptoms for 6 weeks.
😔 Depression, Anxiety, and the "Heart Patient" Identity
Post-cardiac diagnosis depression affects 15–20% of patients and significantly worsens both adherence and prognosis. Patients with angina often grieve their pre-diagnosis identity — the person who could walk briskly, climb stairs, play sport, have spontaneous sex — and replace it with an identity organised around fear and limitation. This grief is rarely articulated and almost never screened for.
"How has having these symptoms been affecting how you feel in yourself — your mood, your sense of energy, whether you're enjoying things? It's really common for people with chest symptoms to feel anxious or low, and it's important we address that alongside the physical treatment."PHQ-9 and GAD-7 at diagnosis and every 3-monthly review. SSRI safe with aspirin + statin (add PPI for GI protection). NHS Talking Therapies referral. Cardiac rehabilitation specifically addresses depression and anxiety alongside exercise capacity.
🏃 Exercise Avoidance and the Deconditioning Trap
Many patients with angina stop all exercise out of fear — which causes rapid cardiac deconditioning, worsening exercise tolerance, further anxiety, and a lower angina threshold. The vicious cycle of pain → fear → avoidance → deconditioning → lower threshold → more pain is one of the most important psychosocial processes in chronic angina. Cardiac rehabilitation breaks this cycle, but only if the patient attends.
"I want to be direct about exercise. It might feel counterintuitive — exercise triggers the pain, so why do it? But supervised cardiac rehabilitation is actually one of the most important treatments for your condition. Your heart muscle gets stronger, your threshold for symptoms improves, and your overall cardiovascular risk decreases. Not exercising actually makes the angina worse over time."Cardiac rehabilitation referral at diagnosis and post-revascularisation. Reduces mortality by ~25% post-MI. Addresses exercise, diet, stress management, medication adherence, and psychosocial wellbeing in an integrated programme. NHS-funded and free at point of care.
- Not checking whether pain is present right now before taking a full history
- Prescribing GTN or any nitrate without screening for PDE5 inhibitor use first
- Accepting "stress" as the diagnosis without investigating the cardiac explanation
- Not asking about sexual activity triggers — misses the PDE5 inhibitor screen and an important psychosocial impact
- Not exploring the father's MI fear — the single most important ICE element in this presentation
- Missing the rest pain question — fails to distinguish stable from unstable angina
999 or Immediate Hospital
Call 999 / ECG now- STEMI — ST elevation on ECG with chest painPrimary PCI <120 minutes from first medical contact; aspirin 300mg loading in GP surgery while 999 in transit; do NOT delay 999 for diagnosis
- Rest chest pain persisting >20 minutes not fully relieved by GTNNSTEMI / unstable angina — HEART score calculation; aspirin loading; anticoagulation pending hospital assessment
- Haemodynamic instability with chest pain (hypotension, shock, acute pulmonary oedema)Cardiogenic shock from large territory MI or mechanical complication; mortality >50% without emergency PCI + IABP/Impella support
- Tearing chest/back pain with BP asymmetry — suspected aortic dissectionDo NOT give aspirin; do NOT thrombolyse; CT aorta; cardiothoracic surgery; Type A = emergency surgical repair
- Exertional syncope + chest pain — suspected severe aortic stenosisUrgent echocardiography; do NOT prescribe vasodilators (nitrates, CCBs as vasodilators) until AS excluded
Same-Day / 2–4-Week Assessment
Within days to 4 weeks- New stable angina — first presentationUrgent cardiology review within 2–4 weeks; CTCA referral; aspirin + statin + beta-blocker started by GP today; NICE NG200
- Crescendo angina (worsening pattern but currently pain-free)Same-day chest pain assessment unit or 999 if deteriorating; HEART score; serial troponins
- Known stable angina — significant deterioration in exercise tolerance despite optimal medical therapyUrgent cardiology for revascularisation discussion; ensure secondary prevention maximised before referral
- New angina with HEART score 4–6 (intermediate risk)Chest pain assessment unit for observation and serial troponins if available; otherwise same-day emergency referral
- Post-PCI recurrence of anginal symptoms (possible in-stent restenosis)Urgent cardiology re-referral; do not restart standard angina workup — expedited pathway for known CAD patients
GP-Led with Investigation
Weeks to months- Stable angina CCS I-II on adequate medical therapyAnnual review: BP, LDL, HbA1c, CCS grade, medication tolerance, depression screen, DVLA
- Investigation workup for typical chest pain (CTCA arranged)Aspirin + statin started while awaiting CTCA; beta-blocker for symptom management; GTN PRN
- Secondary prevention optimisation in known CADLDL target review; BP target; HbA1c in DM; smoking cessation; cardiac rehabilitation referral
- Chest pain likely non-cardiac (musculoskeletal, GORD) with low pre-test probabilityClinical management of most likely cause; safety-net for features that raise cardiac suspicion
- Deferring secondary prevention until after CTCA result — start aspirin and statin today regardless
- Not giving the emergency safety-net for when stable angina becomes unstable
- Giving CTCA request as a routine investigation without explaining what it is and what it will show
- Sending stable angina for 999 without ACS features — over-triage wastes resources and frightens the patient
- Not performing or arranging a resting ECG at first presentation of chest pain
- Missing the heart murmur examination — AS mimics and complicates angina management
- Not checking pulse before prescribing a beta-blocker — bradycardia contraindication
- Not examining for signs of heart failure — changes anti-anginal drug choice
- Ordering exercise treadmill test as first-line — NICE NG200 has replaced ETT with CTCA as first-line for stable chest pain
- Waiting for CTCA result before starting aspirin and statin — secondary prevention starts today
- Not checking TFTs — hypothyroidism is a common reversible exacerbant of angina
- Not explaining what the CTCA is and what will happen after it — patient agreement with investigation is part of the consent process
"Think of your heart like a car engine — it runs on fuel, and the fuel is blood carrying oxygen. The arteries around your heart muscle are called the coronary arteries, and they're the delivery pipes. Over many years, fatty deposits — cholesterol — have been building up inside the walls of those pipes, narrowing them. When you're sitting still, your engine is just ticking over and the narrowed pipe delivers enough fuel. But when you climb stairs or walk briskly, your engine needs to work harder and needs more fuel — and the narrowed artery can't increase delivery fast enough. The muscle sends out a distress signal: that's the tightness you feel in your chest. When you stop and rest, the demand drops, the muscle gets what it needs again, and the pain goes. What we're trying to do is widen the pipe with a scan, improve delivery with medication, and slow down the furring process with cholesterol and blood pressure tablets."
"I think it's probably stress from work — it always seems worse when I've had a difficult week."
"Stress absolutely can make chest symptoms worse — it increases your heart rate and blood pressure, which makes the heart work harder and lowers the threshold for getting the discomfort. But stress as a trigger and this being a problem with the blood supply to your heart are not mutually exclusive. The way you describe it — always on exertion, always going away when you stop — that's the specific pattern of angina, not stress alone. I want to investigate it properly, because understanding what's in those arteries changes what we do about it."
"Could it be indigestion? Sometimes it feels like it's in the stomach area."
"That's a really good question — oesophageal spasm and reflux can cause very similar sensations and can even respond to GTN. The way I distinguish them is the relationship to exertion: true heart pain comes on predictably with a specific level of physical effort and goes with rest. Stomach acid reflux tends to come on after food, when lying flat, or with stress — and doesn't usually go within a few minutes of stopping walking. The scan will answer this definitively."
Unstable Angina / NSTEMI
Crescendo pattern, rest pain, new-onset CCS III-IV, or positive troponin. ACS management: aspirin + P2Y12 inhibitor loading, anticoagulation, same-day hospital. HEART score guides risk stratification.
Vasospastic (Prinzmetal) Angina
Rest pain (often nocturnal), normal coronaries, ST elevation on ambulatory ECG during episode. CCB not beta-blocker — BB may worsen coronary spasm. GTN for acute episodes.
Microvascular Angina (Cardiac Syndrome X)
Typical exertional angina, positive ETT, normal coronaries on ICA. ACEi + statin + sublingual GTN. Beta-blocker or CCB for symptom control. Reassure: low MI risk despite symptoms.
STEMI
ST elevation ≥2mm in ≥2 contiguous leads (≥2.5mm in V2-V3 men <40y; ≥2mm men ≥40y; ≥1.5mm women) or new LBBB + chest pain. Primary PCI <120 min. Aspirin 300mg now. 999 immediately.
Aortic Dissection
Tearing pain to back/interscapular, BP asymmetry between arms, syncope, pulse asymmetry. Type A = surgical emergency (1–2% mortality/hour). Do NOT give aspirin or GTN. CT aorta. 999.
- Using "angina" without explaining what it means — patient may confuse it with a heart attack
- Not distinguishing angina from MI to the patient — failing to address the paternal MI fear directly
- Not challenging the "stress" attribution — accepting it as an alternative to investigation
- Not explaining what the CTCA will tell them and what happens next
- Deferring secondary prevention until after specialist review
- Requesting ETT (treadmill) as first-line instead of CTCA — NICE NG200
- Not explaining what the referral involves and what might happen next
- Prescribing GTN without PDE5 inhibitor screen — potential medico-legal liability
Validate — name their expectation
Many patients expect either immediate reassurance ("it's fine") or immediate action ("I need a stent today"). The patient with a father who had an MI at 58 may be expecting the worst. Naming the expectation — and particularly the underlying fear — before explaining the plan is the single most important communication act in the consultation.
"I can hear that you're worried — and given what happened to your father, that makes complete sense. You're wondering if this is the beginning of the same thing. Can I share what I actually think is happening, and what I want to do about it?"Explain — share your clinical reasoning
Distinguish stable angina from myocardial infarction using the car engine analogy. Explain that angina is a warning signal that can be investigated and treated — not an imminent catastrophe. The investigation (CTCA) will tell us exactly what's happening. The treatments we start today directly reduce the risk of the outcome the patient fears.
"What you have — based on your description — sounds like angina: the artery is narrowed, not blocked. That's very different from a heart attack. We're starting treatment today that specifically reduces the risk of a heart attack. And the scan I'm arranging will tell us how much narrowing there is and whether anything further needs to be done."Negotiate — offer something today
Concrete actions today: four prescriptions (aspirin, statin, beta-blocker, GTN), a written safety-net, a CTCA referral, and a follow-up appointment. The patient should leave knowing they have started treatment, not just been told to wait for a scan.
"Today I'm starting four things: aspirin to protect your heart arteries, a cholesterol tablet, a tablet to lower your heart rate and reduce the demand on your heart, and a GTN spray you can use if the pain comes on. I'm also referring you for the CT scan. You're not going home with nothing — you're going home already on treatment."Supervised progressive exercise improves coronary collateral circulation, endothelial function, and cardiac output. Reduces resting HR and BP. Directly raises the ischaemic threshold — patients can do more before angina develops. Also includes psychological support, dietary advice, and medication education.
NHS-funded. Referred by GP at diagnosis or post-revascularisation. Typically 8–12 weeks, twice weekly. Group-based (also addresses social isolation and depression). Home-based alternatives available. Attendance is strongly predictive of long-term adherence.
Nicotine causes coronary vasospasm, endothelial dysfunction, platelet activation, and accelerated atherosclerosis. Smoking also inactivates the antiplatelet effect of aspirin. Cessation reverses endothelial dysfunction within weeks and reduces excess cardiovascular risk by ~50% within 1 year — more than any single pharmacological intervention.
Combination NRT (patch + gum) + cytisine or varenicline. SMSC referral at every appointment. Set specific quit date within the next 2 weeks. "Every cigarette is a vasoconstrictor injection directly into your heart arteries" is a vivid framing that motivates cessation.
PREDIMED trial: Mediterranean diet reduces major cardiovascular events by 30% in high-risk patients. Mechanisms: anti-inflammatory effect (reduced CRP), antiplatelet effect (omega-3 in fish), BP-lowering (potassium in vegetables), and LDL reduction (olive oil polyphenols replacing saturated fat). Independent of statin benefit.
Replace butter with olive oil (2+ tablespoons/day). Two portions of oily fish/week. ≥5 fruit/vegetable portions daily. Legumes ×3/week. Reduce ultra-processed and high saturated fat foods. Salt <6g/day. Dietitian referral if DM or significant obesity.
Obesity increases cardiac workload, resting HR, and BP — all of which lower the ischaemic threshold. Weight loss of 10% reduces resting BP by 6 mmHg and resting HR by 4 bpm. Central adiposity drives insulin resistance, dyslipidaemia, and systemic inflammation — all accelerating atherosclerosis.
Mediterranean diet as foundation. NHS weight management referral (Tier 2 if BMI >30). GLP-1 agonist (semaglutide) for obesity + established CVD — specifically reduces CV events independently of weight loss (SELECT trial). SGLT2i in DM provides ~2–3kg weight reduction.
Psychological stress activates the HPA axis, raising catecholamines and cortisol — which directly increase HR, BP, platelet aggregation, and inflammation. This lowers the anginal threshold independently of physical exertion. Occupational stress in professional roles is a directly addressable cardiovascular risk factor. Sleep deprivation drives BP elevation.
PHQ-9 and GAD-7 at diagnosis. NHS Talking Therapies referral for stress or health anxiety. Mindfulness-based stress reduction has RCT evidence for reducing angina frequency. Occupational health referral for work modification. Sleep apnoea screening (STOP-BANG) — untreated OSA worsens nocturnal BP and cardiac risk.
Heavy alcohol causes cardiomyopathy, arrhythmia (especially AF), and hypertension — all directly worsening angina. Binge drinking triggers acute catecholamine surges that increase HR and BP. Alcohol also worsens the side effect profile of several anti-anginals: verapamil + diltiazem have reduced clearance with heavy alcohol, increasing bradycardia/hypotension risk.
AUDIT-C at diagnosis. Brief structured intervention. Track weekly units. Avoid alcohol within 30 minutes of GTN use — both are vasodilators and combination causes hypotension. SMSC referral if alcohol use disorder. Document alcohol intake clearly in referral letters — affects surgical candidacy for CABG.
Aspirin 75mg OD + Atorvastatin 80mg OD
- Aspirin 75mg lifelong — NICE CG126 mandates aspirin for all confirmed angina; reduces MI risk ~25%
- Atorvastatin 80mg OD (evening) — all confirmed angina regardless of LDL; target LDL <1.8 mmol/L
- ACEi (ramipril 2.5→10mg) if DM, LV dysfunction, hypertension, or prior MI — not mandatory in stable angina without these, but HOPE trial evidence for all high-risk vascular patients
- If aspirin intolerance: clopidogrel 75mg OD as alternative (CAPRIE evidence)
Bisoprolol 2.5→5mg OD (first-line) or Diltiazem SR 90–120mg BD
- Beta-blocker preferred first-line: bisoprolol 2.5mg OD, titrate to HR 55–60 bpm at rest; reduces angina frequency and improves exercise tolerance; also lowers BP
- If beta-blocker contraindicated (severe asthma, significant bradycardia, significant HF not yet stable): rate-limiting CCB (diltiazem SR or verapamil SR)
- GTN spray (sublingual, 400 micrograms/puff) PRN — give at first appointment with three-spray written protocol; check PDE5 inhibitor use before prescribing
- Targets: resting HR 55–60 bpm; CCS grade improvement; no significant hypotension on exertion
If Step 1 monotherapy insufficient after 4–6 weeks
- Beta-blocker + dihydropyridine CCB (amlodipine 5–10mg) — effective combination; amlodipine (NOT diltiazem/verapamil) with beta-blocker to avoid complete AV block
- Add long-acting nitrate (isosorbide mononitrate modified release): ensure 8-hour nitrate-free period daily (overnight) to prevent tolerance. Absolutely contraindicated with PDE5 inhibitors.
- Add ivabradine 2.5–5mg BD if HR still >70 bpm on beta-blocker; sinus rhythm only; not if significant bradycardia
- Add ranolazine 375mg BD → 750mg BD — does not affect HR or BP; useful add-on in frail, elderly, or hypotensive patients
- Percutaneous Coronary Intervention (PCI / angioplasty + stent): preferred for single-vessel or two-vessel disease. DAPT (aspirin + clopidogrel or ticagrelor) for 6–12 months post-PCI — DO NOT stop without cardiology instruction (stent thrombosis risk)
- CABG (coronary artery bypass graft): preferred for left main stem disease, significant 3-vessel disease, or diabetes with multivessel disease (SYNTAX/FREEDOM trials). Superior long-term patency in complex disease
- Revascularisation improves angina symptoms but does NOT reduce mortality in stable angina compared to optimal medical therapy (COURAGE, ORBITA, ISCHEMIA trials) — inform patient appropriately
- Continue all secondary prevention medications after revascularisation — they are not a substitute for each other
- DM + angina: SGLT2i (empagliflozin/dapagliflozin) for CV secondary prevention; ACEi for renoprotection; HbA1c target <58 mmol/mol
- Vasospastic angina: CCB (amlodipine or diltiazem SR) NOT beta-blocker; beta-blocker may worsen coronary spasm via unopposed alpha vasoconstriction
- COPD + angina: cardioselective bisoprolol safe in mild-moderate COPD; do not withhold without specialist advice; CCB alternative if severe bronchospasm
- Heart failure + angina: bisoprolol + ACEi (both beneficial in HFrEF); avoid rate-limiting CCBs (verapamil, diltiazem) in HFrEF; amlodipine safe in HF
- Post-PCI within 12 months: dual antiplatelet (DAPT) must not be stopped without cardiology guidance — stent thrombosis mortality 50–80%
Select patient characteristics — see drug cards and guidance below
"Spray once under the tongue, sit down, and wait 5 minutes. If the pain isn't gone, spray again. Wait another 5 minutes. If it's still there after a third spray — call 999. That's not a failure of the spray — it's a signal that something more serious may be happening. Also: this spray can interact dangerously with certain tablets for erectile dysfunction — if you're taking sildenafil or similar, please tell me because you cannot use this spray."
The three-spray protocol and the PDE5 inhibitor absolute contraindication are the two highest-value GTN counselling points in SCA. Stating both explicitly = Tasks domain marks. The GTN bottle expiry (replace every 8 weeks) is a commonly missed counselling point that reinforces the GP as knowledgeable and thorough.
"This tablet works by slowing your heart rate, which means your heart does less work and needs less oxygen — so it can go longer before the blood supply becomes insufficient. You might notice your heart feels slower and you might feel a little more tired initially. Most people adjust within a few weeks. Please don't stop this tablet suddenly without talking to me first — stopping abruptly can cause a rebound effect."
Critical SCA teaching points: bisoprolol is CONTRAINDICATED in vasospastic angina (unopposed alpha vasoconstriction worsens spasm) and must NEVER be combined with diltiazem or verapamil (complete AV block risk). NEVER stop abruptly — withdrawal angina/ACS. Target HR 55–60 bpm. Erectile dysfunction as a side effect — proactively counsel before prescribing.
"This tablet relaxes the blood vessel walls — both in the arteries to your heart and throughout your body. For amlodipine, the most common thing people notice is ankle swelling — this isn't dangerous, it's just the medication widening blood vessels in your legs. Let me know if it bothers you and we can adjust. For the diltiazem, it also slows the heart slightly, so you might notice a slower pulse — that's expected and is actually part of how it helps your angina."
Highest-yield SCA CCB fact: amlodipine is the ONLY CCB safe to add to a beta-blocker for angina — never add diltiazem or verapamil to beta-blocker (complete AV block). Also: diltiazem and verapamil are contraindicated in HFrEF. Amlodipine is safe in HF. Stating these distinctions explicitly = Tasks marks.
"This tablet works by relaxing blood vessels to reduce the workload on your heart. Take it first thing in the morning — this is very important because if you take it at two different times of day, your body gets used to it and it stops working. There is a very important warning: this tablet absolutely cannot be combined with certain tablets for erection problems — sildenafil or tadalafil. The combination can cause a dangerous drop in blood pressure. Please check with me before taking anything new."
Nitrate tolerance is the most commonly tested long-acting nitrate fact in SCA. Taking twice-daily ISDN (not ISMN MR) without an adequate nitrate-free period leads to rapid tolerance. ISMN MR once daily (morning) provides the overnight free period automatically. PDE5 inhibitor absolute contraindication applies to ALL nitrates including sublingual GTN and long-acting oral formulations.
"The aspirin keeps your blood platelets less sticky — reducing the risk of a clot forming in a narrowed heart artery. Take it with food to protect your stomach. The cholesterol tablet reduces the fatty deposits in your artery walls. They work together to protect your heart long-term. Take the cholesterol tablet in the evening — it works best then. Both of these are lifelong medicines for you now."
NICE CG126: aspirin 75mg lifelong + atorvastatin 80mg for ALL confirmed angina. Starting both at the first consultation — before CTCA result — = high-value Tasks mark. Never deferring secondary prevention to specialist = major SCA theme. Clopidogrel 75mg alternative if aspirin not tolerated — state this explicitly.
"Ivabradine: 'This tablet specifically slows your heart rate to reduce the work your heart does. It's different from a beta-blocker because it doesn't affect your blood pressure. Some people notice a visual flickering, especially in bright light — this is harmless and usually settles after a couple of months.' Ranolazine: 'This tablet works in a completely different way from your other heart tablets — it protects the heart cells directly during episodes of reduced blood supply, without affecting your heart rate or blood pressure.'"
Ivabradine and AF: ivabradine works ONLY in sinus rhythm — it is absolutely contraindicated in AF (it blocks the sinus node specifically and is ineffective in AF where the ventricular rate is driven by the AV node). This is a high-yield SCA prescribing knowledge point. Ranolazine: useful add-on that does not affect HR or BP — useful in bradycardic or hypotensive patients who cannot tolerate more beta-blocker or CCB.
Driving, DVLA & Occupation
DVLA Group 1 (cars): patients with stable angina may drive provided angina does not occur while driving; symptoms must be controlled; must not drive if chest pain is occurring at the wheel. Must notify DVLA if angina occurs at rest or at the wheel. Must declare to motor insurers.
DVLA Group 2 (HGV/PCV): must notify DVLA; must be free from angina for at least 6 weeks before resuming Group 2 driving; must have satisfactory exercise test and/or functional imaging; stricter ongoing standards than Group 1.
Occupation more broadly: Michael as an accountant is unlikely to face direct occupational restrictions from CCS I-II angina. However, occupational stress is a direct cardiac risk factor — occupational health referral for work modification if stress contributes to symptom burden.
"For your car driving: you can continue as long as the chest pain doesn't come on while you're actually driving. If it ever does — pull over, use your GTN, and if it doesn't go within 5 minutes, call 999. You'll need to declare this to your car insurer."Paternal MI Fear & Mortality Anxiety
For patients with a parent who had a young MI, angina diagnosis carries an almost unbearable resonance. The fear is not abstract — it is a specific scenario the patient has witnessed. Anticipatory grief, health anxiety, and hypervigilance about cardiac symptoms are extremely common in this population and are frequently not addressed in clinical consultations focused on investigation and medication.
The therapeutic task is to transform the paternal history from a predicted future into a motivating story about what is now preventable. "Your father didn't have the treatments available today" is not false reassurance — it is a genuine difference in the standard of care that must be communicated.
CBT-based health anxiety management has RCT evidence in cardiac populations for reducing symptom frequency and improving quality of life. NHS Talking Therapies referral or cardiac psychology referral should be offered at diagnosis for patients with significant health anxiety.
"I can hear that your father's experience is in the background of everything we've been discussing today. I want to be honest with you: your risk is real, and that's why we're acting. But his outcome doesn't have to be yours. The treatments that exist now fundamentally change the trajectory."Sexual Activity & Intimacy
Sexual activity is a common angina trigger (2–5 METs exertion equivalent — climbing 1–2 flights of stairs) that is almost never discussed with patients. Fear of triggering chest pain during sex causes avoidance, loss of intimacy, relationship strain, and significant distress — all of which remain completely invisible in standard consultations.
In men, beta-blocker therapy causes erectile dysfunction in 5–10% — which, when combined with nitrate absolute contraindication to PDE5 inhibitors, creates a situation where neither the drug nor the usual treatment for its side effect is available. This must be proactively discussed, not left for the patient to discover.
For patients with stable angina who are functionally CCS I-II and sexually active: GTN spray prophylactically 5–10 minutes before intercourse is safe and effective (provided NO PDE5 inhibitor is used). Cardiac rehabilitation improves exercise tolerance — directly allowing patients to resume normal activity including sex.
"I want to raise something that might feel a bit unexpected — has any of this affected your intimate life? Many people with angina worry about whether sex will trigger symptoms, and often reduce activity more than they need to. Can we talk about that?"Depression, Anxiety & Health Surveillance
Post-cardiac diagnosis depression affects 15–20% of patients and is an independent predictor of recurrent cardiac events, non-adherence to secondary prevention, and increased mortality. The mechanism is bidirectional: depression increases platelet aggregation, raises inflammatory markers, and drives poor lifestyle behaviours that worsen CAD.
Health anxiety (cardiac surveillance) — hyperawareness of cardiac sensations, constant BP monitoring, fear of exertion — is equally common and equally damaging. It reduces quality of life, increases inappropriate healthcare utilisation, and paradoxically worsens symptoms through heightened sympathetic tone.
PHQ-9 and GAD-7 at diagnosis and every review. SSRI safe alongside aspirin and statin (add PPI for GI protection with aspirin + SSRI combination). NHS Talking Therapies referral for CBT. Cardiac rehabilitation addresses both depression and health anxiety as core programme components.
"I'd like to ask about how you're feeling in yourself — not just the physical symptoms. Getting a diagnosis like this can affect your mood and your sense of what you can safely do. How has it been for you since the symptoms started?"Exercise Avoidance & Deconditioning
The most common maladaptive response to angina is complete exercise avoidance — the patient stops all exertion to prevent pain, leading to rapid cardiac deconditioning, further lowering of the ischaemic threshold, worsening of depression, and progressive loss of function. This vicious cycle is the primary target of cardiac rehabilitation.
Supervised progressive exercise is not just "good for you" — it is a therapeutic intervention with the same evidence base as pharmacological therapy. It is more effective than angioplasty for stable angina in the ORBITA and ISCHEMIA trial contexts for improving quality of life. The patient needs to understand this to engage with rehabilitation.
The evidence: BACR (British Association for Cardiovascular Prevention and Rehabilitation) programme reduces cardiovascular mortality by 25%, increases exercise capacity, reduces depression, and improves medication adherence — across all CCS grades.
"I want to be clear about exercise: it might feel dangerous because it triggers the pain. But avoiding exercise makes your heart less efficient and actually lowers the threshold for getting symptoms. The supervised programme I'm referring you to will specifically help you exercise safely and build up your tolerance."Family Impact & Carer Dynamics
Angina diagnosis affects the entire family system. Partners may become overly protective — preventing exertion, reinforcing avoidance, and amplifying health anxiety. Children in the household (particularly if they have witnessed the patient in pain) may develop anxiety of their own about the parent's mortality. These family dynamics directly affect the patient's rehabilitation trajectory.
Family psychoeducation — engaging the partner in the cardiac rehabilitation process, explaining what triggers angina and what is safe, and normalising resumption of activities — is a powerful intervention that is rarely formalised in primary care.
The widowed, isolated older person with angina has substantially worse outcomes than those with social support — not through medical mechanism alone, but through reduced adherence, reduced help-seeking, and amplified health anxiety without buffering. Social prescribing and community support links are therapeutic for this group.
"Is there someone important in your life who should understand what's happening — a partner or family member? With your permission, it can make a real difference to recovery if the people around you understand what you can safely do and what to watch out for."2–4 Weeks — First Review (Before or After Cardiology Referral)
Medication tolerance: beta-blocker (HR check, fatigue, cold peripheries, BP). Aspirin GI tolerance (add PPI if needed). Statin: any myalgia. GTN technique reinforced — three-spray protocol. CCS grade re-assessed. PDE5 inhibitor screen updated. DVLA advice documented. PHQ-9 first screen. CTCA appointment status.
6–8 Weeks — Post-CTCA or Post-Cardiology Review
CTCA result discussed and implications explained. Anti-anginal titration: if CCS grade still symptomatic → add Step 2 drug (amlodipine). CCS grade documented. Fasting lipids at 3 months (LDL target). HbA1c if DM. BP target review. Smoking cessation update. Cardiac rehabilitation referral confirmed. Long-acting nitrate if Step 2 insufficient (ensure nitrate-free period and PDE5 inhibitor excluded).
3 Months — Stability Assessment
CCS grade trend — improving, stable, worsening. If worsening despite maximum tolerated medical therapy: urgent cardiology for revascularisation discussion. Fasting lipids confirmed at target; add ezetimibe if LDL >1.8 on atorvastatin 80mg. PHQ-9 second screen. Cardiac rehabilitation attendance and progress. Smoking cessation update. DVLA status update. SGLT2i in DM.
6 Months — Revascularisation Outcome or Ongoing Medical Management
Post-PCI: DAPT compliance (aspirin + clopidogrel/ticagrelor) — must not stop without cardiology guidance. Post-CABG: secondary prevention medications all in place; wound healing; cardiac rehabilitation completion. Medical management: anti-anginal review; any referral for refractory symptoms. PHQ-9. Any new symptoms since last review (rest pain, crescendo = urgent upgrade).
Annual — Secondary Prevention Review
Full CV risk review: BP, LDL, HbA1c, BMI, smoking, alcohol. ECG if symptoms changed. CCS grade. Medication review: any intolerance, any additions needed (ezetimibe, PCSK9i, ivabradine, ranolazine). PHQ-9 and GAD-7. Exercise capacity (MET equivalent). DVLA status. Cardiac rehabilitation outcomes. Screen for worsening symptoms — upgrade urgency if any crescendo or rest pain.
Memory rule — the angina monitoring triad
At every angina review: CCS grade (is the symptom burden improving?); LDL <1.8 mmol/L on atorvastatin 80mg (add ezetimibe if not reached; PCSK9i if dual therapy fails); BP <140/90 (or <130/80 in DM). Check HR on beta-blocker (target 55–60 bpm). GTN use frequency — more than 2–3 times/week = anti-anginal therapy inadequate. PHQ-9 at every review. PDE5 inhibitor screen before every nitrate prescription.
⚠ Three scenario-specific phrases — use these verbatim
Why safety-netting matters beyond clinical care
- Prescribing GTN without checking PDE5 inhibitor use — the most dangerous prescribing error in angina
- Not giving the ACS transition safety-net (rest pain / 20 min / three sprays = 999)
- Not counselling about beta-blocker abrupt discontinuation danger
- Deferring aspirin and statin until CTCA result — secondary prevention starts today
- Not addressing the paternal MI fear — the consultation's dominant emotional agenda
- Not mentioning cardiac rehabilitation — one of the most effective interventions for stable angina
- PDE5 inhibitor screen BEFORE prescribing GTN
- GTN three-spray protocol — verbally and in writing
- ACS transition safety-net (rest pain / >20 min / no GTN response = 999)
- Aspirin + atorvastatin 80mg started today — not after CTCA
- Bisoprolol: HR target, no abrupt discontinuation counselling
- Paternal MI fear directly addressed and reframed with evidence
- Sexual activity and PDE5 inhibitor explored proactively and empathetically
- Stress attribution challenged with clinical reasoning — not dismissal
- ICE all three explored and explicitly referenced in the plan
- Car engine analogy used for diagnosis explanation
- Closing question asked genuinely — patient given space to ask
Who you are
Michael Okafor, 57-year-old accountant at a mid-size firm in the City. Married with two adult children. Ex-smoker — 10 pack-years, stopped 5 years ago. Type 2 diabetes on metformin 1g BD (last HbA1c 64 mmol/mol, 9 months ago). Hypertension on ramipril 5mg OD (BP today 148/88). No other regular medications. No known cardiac history. Father had a MI aged 58 and survived but "was never the same afterwards." Michael was present for much of his father's recovery. He is now 57 — one year younger than his father was when the MI happened. This is the central fact shaping every aspect of his anxiety.
Hidden agenda (two layers)
Layer 1 — Paternal MI fear: Michael is quietly terrified he is experiencing the beginning of what happened to his father. He has not told his wife how worried he is because he does not want to frighten her. He will not volunteer this fear spontaneously — but if the doctor asks about concerns, or asks about family history in an open and empathetic way, he will admit that he has been thinking about his father constantly since the symptoms started. If this fear is not acknowledged and addressed directly, Michael will leave the consultation more anxious than he arrived — even if the prescription was correct.
Layer 2 — Erectile dysfunction and sildenafil use: Michael takes sildenafil 50mg occasionally (obtained online, approximately once a week) for erectile dysfunction. He has not disclosed this to any doctor because he is embarrassed. If the doctor screens specifically for PDE5 inhibitor use — by name, in a non-judgmental way — Michael will confirm it. If the question is vague ("any other tablets?") he will not volunteer it. This is the absolute contraindication to GTN prescribing and must be elicited.
Symptoms if asked directly
- Central chest tightness — "like a heavy pressure" — not sharp, not burning
- Comes on when rushing for the Tube, climbing more than one flight of stairs, or walking quickly uphill
- Consistent onset after approximately the same level of activity — not getting worse but not improving
- Completely gone within 4–5 minutes of stopping and standing still
- Radiation: if asked specifically, admits a mild ache down the left arm on the occasions when the tightness is worse
- No rest pain — never at rest, never at night
- No syncope or near-syncope (deny if asked)
- Has not tried GTN — does not have it
- Breathlessness: slight shortness of breath when the pain is on — nothing he would describe independently as breathlessness
- No palpitations
Lifestyle + bonus details
- Alcohol: 15–18 units/week — denies it's excessive ("just with meals and social")
- Diet: business lunches, irregular eating, limited fresh vegetables; family eat together in the evenings
- Exercise: almost none intentional since symptom onset — has been avoiding stairs where possible, taking lifts
- Work stress: significant — deadline project running 3 months; working long hours; sleeping poorly. Attributes the chest symptoms to this. Resistant to cardiac investigation initially.
- GTN + sildenafil interaction: If the candidate prescribes GTN without asking about PDE5 inhibitors, and Michael is prompted (in the debrief) to reveal sildenafil use, this creates the teaching moment. In the examination itself: candidate must screen first — Michael will not volunteer it unless asked by name.
- Beta-blocker and erectile dysfunction: If bisoprolol is prescribed and the candidate mentions erectile dysfunction as a possible side effect, Michael will say: "Actually, I already have difficulty with that — I take sildenafil for it." This reveals the PDE5 inhibitor use and creates the contraindication discussion even if the earlier screen was missed.
- Stress attribution challenge: Michael is initially resistant to the cardiac explanation ("my colleague said it's probably stress, I'm sure he's right"). He will accept the cardiac explanation if the doctor: (a) validates that stress can contribute; (b) specifically explains why the exertional pattern is not consistent with stress alone; and (c) frames the investigation as clarifying, not alarming.
Resolution: Michael will engage fully with the management plan if the candidate: (1) screens for PDE5 inhibitor use specifically and responds appropriately (GTN not prescribed; alternative anti-anginal discussed; ED management options offered); (2) names the paternal MI fear directly ("I think there's something else worrying you — is it about your father?") and reframes it with evidence; (3) explains that CTCA (not ETT) is the current first-line investigation with a brief explanation of why; (4) starts all secondary prevention today without deferral; (5) is warm and non-alarmist while being completely honest. He will disengage if the doctor: prescribes GTN without asking about sildenafil; accepts "stress" as the diagnosis without cardiac investigation; fails to acknowledge the paternal MI fear; or is overly clinical and formulaic without connecting the treatment to his personal context.

| Drug / Target | Test | Timing | Action threshold |
|---|---|---|---|
| Atorvastatin 80mg | Fasting lipids + LFTs + CK | 3 months; annually | LDL >1.8 → add ezetimibe. ALT >3× ULN → reduce/switch statin. CK >5× + symptoms → stop urgently. |
| Bisoprolol (HR) | HR + BP at every visit | Every review | HR <50 → hold; reduce. HR >70 on max BB → add ivabradine (sinus only). NEVER stop abruptly. |
| ACEi (if prescribed) | U&E + eGFR | 2 weeks post-start; annually | Cr ↑ >25% → hold; investigate RAS. K⁺ >6.0 → stop urgently. Cough → ARB switch. |
| CCS Grade (symptom burden) | Clinical assessment | Every review | CCS III-IV on max medical therapy → urgent cardiology. Any worsening = anti-anginal Step 2. New rest pain = ACS until proven otherwise. |
| GTN use frequency | Patient self-report | Every review | >2–3×/week → anti-anginal inadequate; upgrade therapy. GTN multiple times daily = unstable — urgent review. |
