Abstract |
Low-density lipoprotein cholesterol (LDL-C) and lipoprotein(a) (Lp(a)) are established causal risk factors for cardiovascular disease (CVD). Efficacy, safety, and tolerability of lipoprotein apheresis (LA) were investigated in 118 patients with CVD covering a period with 36,745 LA treatments in a retrospective, monocentric study. Indications for LA were severe hypercholesterolemia (n = 83) or isolated Lp(a) hyperlipoproteinemia (Lp(a)-HLP) (n = 35). In patients with hypercholesterolemia, initial pre-LA LDL-C was 176.4 ± 67.0 mg/dL. In patients with isolated Lp(a)-HLP, initial pre-LA Lp(a) was 127.2 ± 67.3 mg/dL. Mean reduction rates of LA were 67 % for both LDL-C and Lp(a). During chronic LA, the average annual rate of major adverse cardiac events of all patients declined by 79.7 % (p < 0.0001). Subgroup analysis showed decline by 73.7 % (p < 0.0001) in patients with severe hypercholesterolemia, and by 90.4 % (p < 0.0001) in patients with isolated Lp(a)-HLP. Adverse events occurred in 1.1 % of treatments. LA treatment of patients with a high risk for CVD due to hypercholesterolemia and/or Lp(a)-HLP demonstrated clinical benefit and was safe and well tolerated. |
