Management of Ischemia, Bradycardia, and Angina Pectoris

Initial Assessment and Risk Stratification

• The American College of Cardiology recommends assessing the severity of angina using the Canadian Cardiovascular Society classification system 3
• Review results of stress testing and MCT to evaluate chronotropic competence and the relationship between bradycardia and anginal symptoms 3

Pharmacological Management

• The American College of Cardiology recommends beta-blockers as the first-line treatment for patients with ischemia, bradycardia, and angina pectoris, combined with nitrates and consideration for coronary revascularization based on the severity of symptoms and coronary anatomy 1, 2
• Beta-blockers are the drugs of first choice for patients with CAD and angina, as they alleviate ischemia through negative inotropic and chronotropic actions 4, 5
• Nitrates should be used in combination with beta-blockers for symptom relief 1, 2
• ACE inhibitors or ARBs should be added, particularly in patients with left ventricular dysfunction, diabetes mellitus, or hypertension 2, 6
• Antiplatelet therapy with aspirin and/or clopidogrel should be initiated 8

Blood Pressure Management

• The American Heart Association recommends a target blood pressure of <130/80 mmHg for patients with established CAD 6
• In patients with left ventricular dysfunction, consider lowering BP further to <120/80 mmHg 6
• Exercise caution when lowering diastolic BP below 60 mmHg, especially in patients over 60 years or with diabetes mellitus 6

Revascularization Considerations

• Strong consideration should be given to coronary revascularization in patients with both heart failure and angina pectoris 1, 2
• Coronary artery bypass surgery has been shown to lessen angina and reduce mortality risk in patients with multivessel disease, reduced left ventricular ejection fraction, or stable angina 1, 2

Lifestyle Modifications

• The European Society of Cardiology recommends encouraging smoking cessation, a Mediterranean diet, weight reduction, moderate physical activity, and optimization of comorbidities such as diabetes mellitus and hyperlipidemia 7, 8

Monitoring and Follow-up

• Regularly assess angina frequency, severity, and response to therapy 8
• Monitor for signs of worsening ischemia or heart failure 9, 10
• Consider repeat stress testing or coronary angiography if symptoms worsen despite optimal medical therapy 8, 3
