Meaning of low-density lipoprotein-apheresis for hypercholesterolemic patients at high risk for recurrence of coronary heart disease.
The goal of cholesterol-lowering therapy in hypercholesterolemic patients at high risk for recurrence of coronary heart disease (CHD) is the prevention of acute coronary syndrome by stabilization of coronary atheromatous plaque. We often encounter patients in whom it is difficult to maintain the serum cholesterol level at a desirable level with dietary therapy and drug treatment, despite the development and use of statins. For secondary prevention in patients who are at high risk for the recurrence of CHD and whose cholesterol level cannot be controlled by drugs alone, low-density lipoprotein (LDL)-apheresis therapy, which involves removal of LDL through extracorporeal circulation, is now available. Many reports concerning improvement of vascular endothelial function, improvement of myocardial ischemia, regression of coronary atherosclerotic lesions, stabilization of coronary plaque, and reduction in the incidence of cardiac events as a result of LDL-apheresis treatment have been published in various countries. We believe that LDL-apheresis should be performed on hypercholesterolemic patients with existing CHD for whom diet and maximum cholesterol-lowering drug therapies have been ineffective or not tolerated and whose LDL cholesterol level is 160 mg/dL or higher.
