title: Clinical application and effectiveness of low-density lipoprotein apheresis in the treatment of coronary artery disease.
abstract: The Low-Density Lipoprotein Apheresis Coronary Atherosclerosis Prospective Study (L-CAPS) examined whether or not combined low-density lipoprotein (LDL) apheresis and drug therapy apheresis could induce the regression of coronary atherosclerotic lesions in patients with familial hypercholesterolemia. Twenty-eight patients treated with LDL apheresis and drugs and 11 patients treated with drugs alone underwent sequential coronary angiography 2.5 years apart. The frequency of cases with regression or no change was significantly higher for the apheresis group than for the control group (p = 0.004). The LDL apheresis Angioplasty Restenosis Trial (LART) investigated the hypothesis that high plasma lipoprotein (a) (Lp[a]) levels were associated with increased incidences of restenosis after coronary angioplasty. Two days before and 5 days after angioplasty, 66 patients underwent LDL apheresis. The restenosis rates were 21% in the 42 patients whose Lp(a) levels were reduced > or = 50% and 50% in the 24 patients whose Lp(a) levels were reduced < 50% (p < 0.05). LDL apheresis is effective in the prevention of the progression of coronary atherosclerosis. Its potential application in restenosis prevention should be further investigated.
