Management of Chronic Coronary Syndromes: Comprehensive Cardiology Recommendations
All patients with chronic coronary syndromes require comprehensive risk factor management including statins, blood pressure control to 120-130 mmHg (130-140 mmHg if >65 years), and treatment of diabetes, with myocardial revascularization indicated when angina persists despite optimal antianginal therapy. 1
Core Medical Therapy
Lipid Management
- Statins are mandatory for all CCS patients to reduce morbidity and mortality 1
- If LDL goals are not achieved with maximum tolerated statin dose, add ezetimibe 1
- For very high-risk patients not at goal despite statin plus ezetimibe, add a PCSK9 inhibitor 1
Blood Pressure Control
- Target systolic BP 120-130 mmHg in general population 1
- Target systolic BP 130-140 mmHg in patients >65 years 1
- In hypertensive patients with recent MI, use beta-blockers AND RAS blockers (ACE inhibitors or ARBs) 1
- In symptomatic angina, use beta-blockers and/or calcium channel blockers 1
- Never combine ACE inhibitors with ARBs - this is contraindicated 1
ACE Inhibitors/ARBs
- ACE inhibitors (or ARBs if intolerant) are indicated in presence of heart failure, hypertension, or diabetes 1
- Specifically recommended in CCS patients with diabetes for event prevention 1
Diabetes Management in CCS
- Control BP, LDL-C, and HbA1c to target values 1
- SGLT2 inhibitors (empagliflozin, canagliflozin, or dapagliflozin) are recommended in patients with diabetes and CVD 1
- GLP-1 receptor agonists (liraglutide or semaglutide) are recommended in patients with diabetes and CVD 1
- Perform periodic resting ECG in asymptomatic diabetic patients to detect conduction abnormalities, atrial fibrillation, and silent MI 1
Antianginal Therapy
Symptomatic Patients
- Beta-blockers and/or calcium channel blockers for symptomatic angina 1
- Proceed to myocardial revascularization when angina persists despite antianginal drug treatment 1
Antithrombotic Management
Standard CCS
- Aspirin monotherapy is standard 1
- Add proton pump inhibitor in patients at high risk of gastrointestinal bleeding receiving aspirin monotherapy, DAPT, or OAC monotherapy 1
Post-PCI with Atrial Fibrillation
- Peri-procedural aspirin and clopidogrel are required for coronary stent implantation 1
- Use a NOAC (apixaban 5 mg BID, dabigatran 150 mg BID, edoxaban 60 mg daily, or rivaroxaban 20 mg daily) in preference to warfarin when combining with antiplatelet therapy 1
- Never use ticagrelor or prasugrel as part of triple antithrombotic therapy with aspirin and OAC 1
Atrial Fibrillation Management
- When initiating oral anticoagulation in AF patients eligible for NOAC, prefer NOAC over warfarin 1
- Long-term OAC (NOAC or warfarin with time in therapeutic range >70%) is required for CHA₂DS₂-VASc score >2 in males or >3 in females 1
Heart Failure with CCS
Rate Control in HF with Preserved Ejection Fraction
- Beta-blocker or nondihydropyridine calcium channel antagonist for resting heart rate control 1
- Combination of digoxin plus beta-blocker (or nondihydropyridine CCB in HFpEF) is reasonable for controlling resting and exercise heart rate 1
HF with Reduced Ejection Fraction
- Beta-blockers are essential - they relieve angina AND reduce morbidity and mortality 1
- ACE inhibitor therapy is mandatory in symptomatic HF or asymptomatic LV dysfunction post-MI to improve symptoms and reduce morbidity and mortality 1
- ARB as alternative if ACE inhibitor not tolerated, or angiotensin receptor-neprilysin inhibitor for persistent symptoms despite optimal therapy 1
- Add mineralocorticoid receptor antagonist (MRA) if symptomatic despite ACE inhibitor and beta-blocker to reduce morbidity and mortality 1
- Diuretics for symptomatic pulmonary or systemic congestion 1
Device Therapy in HF
- Implantable cardioverter-defibrillator (ICD) is indicated for documented ventricular dysrhythmia causing hemodynamic instability (secondary prevention) AND for symptomatic HF with LVEF <35% (primary prevention) to reduce sudden death and all-cause mortality 1
- Cardiac resynchronization therapy (CRT) is indicated for symptomatic HF patients in sinus rhythm with QRS ≥150 ms and LBBB morphology, with LVEF <35% despite optimal medical therapy 1
- CRT is also indicated for QRS 130-149 ms with LBBB and LVEF <35% 1
- In HF with bradycardia and high-degree AV block requiring pacing, use CRT with pacemaker rather than right ventricular pacing 1
Risk Stratification and Follow-up
Asymptomatic Patients
- Periodic cardiovascular healthcare visits to reassess risk status, lifestyle modifications, cardiovascular risk factor targets, and comorbidities 1
- In mild/no symptoms on medical treatment with high-risk non-invasive stratification, invasive coronary angiography (with FFR when necessary) is indicated if revascularization considered for prognosis improvement 1
- Coronary CTA is NOT recommended as routine follow-up for established CAD 1
- ICA is NOT recommended solely for risk stratification 1
Symptomatic Patients
- Risk stratification using stress imaging (preferred) or exercise stress ECG for new or worsening symptoms 1
- Expeditious referral for evaluation with significant symptom worsening 1
- ICA (with FFR/iwFR when necessary) for risk stratification in severe CAD, particularly if symptoms refractory to medical treatment or high-risk clinical profile 1
- Reassess CAD status in deteriorating LV systolic function without reversible cause (e.g., tachycardia, myocarditis) 1
Vasospastic Angina
- Obtain ECG during angina if possible 1
- Invasive angiography or coronary CTA is indicated in characteristic episodic resting angina with ST-segment changes resolving with nitrates/calcium antagonists to determine extent of underlying coronary disease 1
- First-line therapy: calcium channel blocker (e.g., verapamil 40 mg BID uptitrated) 1
- Second-line: add long-acting nitrate (e.g., isosorbide mononitrate 10 mg BID) 1
Special Populations
Valvular Heart Disease
- ICA is required before valve surgery if any of: history of CVD, suspected myocardial ischemia, LV systolic dysfunction, men >40 years, postmenopausal women, or ≥1 cardiovascular risk factor 1
- ICA indicated for evaluation of moderate-to-severe functional mitral regurgitation 1
- Do NOT routinely use stress testing in severe valvular disease to detect CAD due to low diagnostic yield and potential risks 1
Active Cancer
- Base treatment decisions on life expectancy, comorbidities (thrombocytopenia, thrombosis propensity), and drug interactions between CCS medications and antineoplastic agents 1
- If revascularization indicated in highly symptomatic patients with active cancer and increased frailty, use the least invasive procedure 1
Chronic Kidney Disease
- Control risk factors to target values 1
- Pay special attention to dose adjustments of renally excreted drugs 1
- Minimize iodinated contrast agents in severe CKD with preserved urine production to prevent further deterioration 1
Elderly Patients
- Pay particular attention to drug side effects, intolerance, and overdosing 1
Screening in Asymptomatic Subjects
- Use SCORE risk estimation system for asymptomatic adults >40 years without CVD, diabetes, CKD, or familial hypercholesterolemia 1
- Assess family history of premature CVD (fatal/non-fatal CVD event or established CVD diagnosis in first-degree male relatives <55 years or female relatives <65 years) 1
- Screen individuals <50 years with family history of premature CVD in first-degree relative for familial hypercholesterolemia using validated clinical score 1
- Carotid ultrasound IMT is NOT recommended for cardiovascular risk assessment 1
- Coronary CTA or functional imaging is NOT indicated in low-risk non-diabetic asymptomatic adults 1
- Routine circulating biomarkers are NOT recommended for cardiovascular risk stratification 1
Critical Pitfalls to Avoid
- Never combine ACE inhibitors with ARBs 1
- Never use ticagrelor or prasugrel in triple antithrombotic therapy 1
- Never give IV nondihydropyridine calcium channel antagonists, IV beta-blockers, or dronedarone in decompensated heart failure 1
- Never perform AV node ablation without pharmacological trial to control ventricular rate 1
- Never use coronary CTA as routine follow-up in established CAD 1
- Never perform ICA solely for risk stratification 1
