Despite the success of coronary interventions in the treatment of stenosis due to coronary atherosclerosis, it behooves cardiologists to treat the underlying disease by decreasing patients' cholesterol levels. Intravascular ultrasound has made it possible to detect plaque accumulation not visible on angiography. Although advanced lesions that are fibrous and calcific can be treated with atherectomy and lasers, it is the soft, lipid-laden plaque that is particularly vulnerable to rupture and leads to coronary events. Therefore, attention must also focus on decreasing atherosclerotic progression in patients who have undergone coronary interventions. Studies have clearly shown the value of cholesterol reduction in decreasing coronary events. However, a review of cardiologists' practices shows that more aggressive lipid-lowering therapy is needed. One way to achieve this goal is to treat and monitor patients who have undergone revascularization procedures and to encourage patients to become more involved in their own care.
