Management of Mild Coronary Artery Disease
Statin Therapy
- The European Society of Cardiology recommends high-intensity statin therapy for all patients with any evidence of coronary artery disease, including mild CAD detected on CT calcium scanning, with a target LDL-C of <1.4 mmol/L and at least 50% reduction from baseline 1, 2, 3
- High-intensity statin therapy should be initiated immediately to reach aggressive LDL-C goals, and if targets are not achieved, combination with ezetimibe or addition of a PCSK9 inhibitor should be considered 1, 2, 3
Aspirin Therapy
- The European Society of Cardiology recommends aspirin 75-100 mg daily lifelong for patients with CAC ≥100, as benefits exceed bleeding risks, particularly when CAC >400 1, 2, 4
- For patients with CAC 1-99, aspirin may be considered but is not universally recommended, and the decision should weigh individual bleeding risk against ischemic risk 4
- Aspirin is generally not recommended for patients with CAC = 0, unless 10-year ASCVD risk exceeds 20% 4
Bleeding Risk Assessment and Management
- Before initiating aspirin, assess bleeding risk factors, including history of gastrointestinal bleeding, concurrent use of anticoagulants or NSAIDs, age >70 years, thrombocytopenia, and uncontrolled hypertension 1, 3
- For patients at increased gastrointestinal bleeding risk who are prescribed aspirin, concomitant proton pump inhibitor therapy is recommended 1, 3, 5
Alternative Therapies
- Clopidogrel 75 mg daily is recommended as a safe and effective alternative if aspirin is not tolerated 1, 2, 3, 5
- ACE inhibitors or ARBs are recommended for patients with CAD, especially those with hypertension, diabetes, heart failure, or LV dysfunction 3, 5, 6
- Beta-blockers should be considered for symptom control and are particularly important if there is LV dysfunction or prior MI 1, 3, 5
