Lipoprotein (a) [Lp (a)] is a risk factor for coronary heart disease (CHD), especially in the presence of a raised low-density lipoprotein (LDL)-cholesterol (LDL-C). To ascertain whether reduction of both LDL and Lp(a) is more advantageous than reduction of LDL alone, patients with heterozygous FH and CHD were selected randomly to receive either LDL apheresis fortnightly plus simvastatin 40 mg/day or colestipol 20 g plus simvastatin 40 mg/day. Quantitative coronary angiography was undertaken before and after 2.1 years. Changes in serum lipids were similar in both groups except for the greater reduction of LDL-C and Lp(a) by apheresis. There were no significant differences in primary angiographic endpoints, and none of the angiographic changes correlated with Lp(a). Although LDL apheresis plus simvastatin was more effective than colestipol plus simvastatin in reducing LDL-C and Lp(a), it was not more beneficial in influencing coronary atherosclerosis. Decreasing Lp(a) seems unnecessary if LDL-C is reduced below 130 mg/dl.
