Lipoprotein (a) and coronary heart disease - is there an efficient secondary prevention?

Abstract

Lipoprotein (a) (Lp (a)) is one risk factor for the development of cardiovascular diseases. Several studies have shown that Lp (a) hyperlipoproteinaemia has a particular influence on the development of coronary heart disease (CHD). A retrospective single-centre observation study was performed to evaluate the effectiveness of lipid apheresis on the basis of consecutively performed percutaneous coronary interventions (PCI) in patients with high Lp (a) values and angiographically documented CHD.In 23 pts (male 18, age 60.04 ± 0.58 years) with angiographically documented CHD (first manifestation 48.00 ± 9.41 years), elevated LDL cholesterol (144.39 ± 92.01 mg/dl) and Lp (a) (133.04 ± 39.68 mg/dl), 49 PCI and 3 coronary artery bypass grafting (CABG) procedures had been performed prior to the initiation of lipid apheresis. Following the initiation of weekly lipid apheresis, LDL cholesterol was 99.43 ± 36.53 mg/dl and Lp (a) 91.13 ± 33.02 mg/dl. In a time interval of 59.87 ± 49.49 months (median 51.00, range 1-153 months) 15 pts did not require an additional PCI. In 8 pts (7 pts 3‑vessel disease, 1 pt 2‑vessel disease) 14 PCI - no CABG - were performed after 69.38 ± 71.67 months (median: 32.50, range 17-232 months). The incidence of PCI could thus be reduced by 71.43%.
