What supplements have evidence for coronary artery disease support?

Omega-3 EPA (the REDUCE-IT trial), plant sterols for LDL reduction, and CoQ10 for cardiac energy metabolism have the most relevant evidence. Aged garlic extract has shown reduced coronary calcium progression in the LA BioMed study. However, these supplements complement rather than replace guideline-directed therapy for CAD.

Can supplements alone manage coronary artery disease?

No. CAD management requires evidence-based medications including antiplatelet agents, statins, beta-blockers, and ACE inhibitors/ARBs as indicated. Lifestyle changes including Mediterranean diet, regular exercise, and smoking cessation are essential. Revascularization may be needed for significant blockages. Supplements may provide modest adjunctive benefits.

When should someone with CAD see a doctor about supplement use?

All CAD patients should discuss supplements with their cardiologist. Many supplements interact with cardiac medications. New or worsening chest pain, shortness of breath during exertion, or pain radiating to the arm or jaw requires immediate emergency evaluation. Do not delay seeking care to try supplements.
