Optimal cardiovascular medical therapy: current guidelines and new developments.

Coronary artery disease is a leading cause of mortality worldwide, and patients with obstructive coronary artery disease require optimal cardiovascular medical therapy along with lifestyle modification for secondary prevention of future cardiac events. Optimal medical therapy includes antiplatelet agents, high-intensity statins, beta-blockers, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, aldosterone antagonists, and calcium channel blockers. There are differences in the medical therapy guidelines of the American Heart Association/American College of Cardiology and the European Society of Cardiology. In addition, there are emerging medical therapies that may be added to future guidelines with additional cardiovascular outcome benefits.
