Management of Angina Pectoris with Abnormal EKG and Bradycardia
Risk Stratification
- The American College of Cardiology recommends that patients with angina pectoris, abnormal EKG consistent with ischemia, and bradycardia be considered high-risk and referred for coronary angiography to evaluate for revascularization 1, 2
- Abnormal EKG consistent with ischemia is a high-risk feature that warrants an invasive strategy 1, 3
Next Steps in Management
- The American Heart Association suggests that coronary angiography is indicated for patients with high-risk features, such as abnormal EKG consistent with ischemia, to determine the extent of coronary artery disease and guide revascularization options (PCI or CABG) 1, 2, 4
- The American College of Cardiology recommends initiating or optimizing anti-ischemic medications following the ABCDE approach, including aspirin, beta-blockers (with caution due to bradycardia), cholesterol management with high-intensity statin, diet modification and diabetes management, and exercise counseling and education 5, 2, 6
- Sublingual nitroglycerin is recommended for acute angina episodes, and long-acting nitrates may be considered if beta-blockers are contraindicated due to bradycardia 5, 7
Management Algorithm
- Immediate referral for coronary angiography is recommended based on high-risk features 1, 2
- While awaiting angiography, initiate antiplatelet therapy (aspirin) and consider antianginal therapy with nitrates rather than beta-blockers due to bradycardia, and start high-intensity statin therapy 5, 6
- Based on angiography findings, if significant CAD amenable to revascularization is found, proceed with PCI or CABG, and if no significant obstructive CAD is found, reassess diagnosis and consider other causes of angina 2, 4, 8
- Post-revascularization or if medical management is chosen, optimize secondary prevention medications, provide patient education on angina management, and consider cardiac rehabilitation 5, 7
