Reducing residual risk for patients on statin therapy: the potential role of combination therapy

Abstract

Cholesterol-lowering therapy with 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, or statins, has been established as an effective method of reducing death and myocardial infarction among patients with coronary artery disease (CAD). However, a significant number of patients receiving statin therapy continue to have high residual risk. An important clinical challenge exists in reducing residual CAD risk with optimal therapies without increasing adverse effects. Combination therapy appears most appropriate for patients with a high rate of events of residual risk despite optimal statin therapy. This article discusses the role of combination therapy in managing CAD and in achieving optional targets in high-risk patient populations.
