Comprehensive Management of Coronary Artery Disease

Primary Prevention Strategies

• The American College of Cardiology recommends calculating 10-year Framingham risk score for all patients with 2 or more major risk factors to guide primary prevention intensity 4
• The American Heart Association recommends target BP <130/80 mmHg for patients with diabetes, chronic renal disease, CAD or CAD risk equivalents, and target BP <140/90 mmHg for individuals without these conditions 5
• First-line agents for blood pressure management include ACE inhibitors, thiazide diuretics, and calcium channel blockers 5
• Statins are recommended for all patients with elevated LDL-C, even with mild-to-moderate elevations 6, 7
• Aspirin (75-162 mg daily) is recommended for patients at high cardiovascular risk 7
• Avoid dipyridamole as it can enhance exercise-induced myocardial ischemia 6, 7
• Smoking cessation with pharmacotherapy support as needed is recommended 4
• Regular physical activity (moderate-to-vigorous) is recommended 8
• Heart-healthy diet (Mediterranean, DASH, or AHA diet) is recommended 2, 3
• Weight management targeting appropriate BMI is recommended 2

Secondary Prevention Strategies

• The American College of Cardiology recommends aspirin (75-162 mg daily) indefinitely for all patients with CAD 1, 2, 3, 9
• Clopidogrel 75 mg daily, prasugrel 10 mg daily, or ticagrelor 90 mg twice daily for at least 12 months with drug-eluting stents and up to 12 months with bare-metal stents is recommended for patients with recent ACS or stent placement 1
• Beta-blockers are recommended as first-line therapy for all patients with previous MI and for symptom control in angina 6, 7
• ACE inhibitors are recommended for all patients with CAD, particularly those with diabetes, systolic dysfunction, or both 6, 7
• Beta-blockers are particularly beneficial for their negative inotropic and chronotropic effects 5
• Beta-blockers are not contraindicated in diabetes; diabetic patients may benefit as much or more than non-diabetics 6, 7

Long-Term Follow-Up After CAD

• Regular follow-up visits to monitor symptoms, medication adherence, and risk factor control are recommended 1, 2
• Consider telephone follow-up weekly for the first 4 weeks after discharge to reinforce education and address concerns 1, 2, 3
• Enrollment in cardiac rehabilitation programs after discharge enhances patient education and compliance 1, 2, 3
• Cardiac rehabilitation provides supervised exercise, risk factor modification, and psychosocial support 8
• Cardiac rehabilitation reduces cardiovascular mortality and hospital readmissions 8
• Regular monitoring of lipid levels, blood pressure, and glycemic control is recommended 2, 3
• Utilize healthcare team with expertise in CAD management (physicians, nurses, dietitians, pharmacists, rehabilitation specialists) 1, 2, 3
• Family education to support the patient's lifestyle changes is recommended 2

Common Pitfalls and Caveats

• In patients with elevated DBP and CAD with evidence of myocardial ischemia, lower BP slowly and cautiously 5
• Avoid reducing DBP below 60 mmHg in patients over 60 years or with diabetes 5
• Implement strategies to improve referral and participation rates in cardiac rehabilitation 8
• Addressing single risk factors is insufficient; combination therapy targeting multiple risk factors provides complementary benefits 2, 3
