Is low density lipoprotein apheresis effective for coronary artery disease?

Low density lipoprotein (LDL) apheresis is one type of therapy currently being used for coronary artery disease; however, there has been no study to compare the effectiveness of this therapy with the effectiveness of other treatments, such as coronary artery bypass grafting (CABG) and percutaneous transluminal coronary angioplasty (PTCA). In this study, we evaluated the clinical results of these three therapies to compare their individual effectiveness for the treatment of coronary artery disease. Forty-four patients with two vessel disease (plasma cholesterol levels > 250 mg/dl) were divided into three groups (L, LDL apheresis; C, CABG; I, PTCA).
