LDL-apheresis is a treatment option for patients with coronary heart disease and severe hypercholesterolemia not adequately responding to drug treatment. 34 patients (21 men, 13 women), aged 47 +/- 9 years, with coronary heart disease and heterozygous familial hypercholesterolemia not adequately responsive to lipid lowering drugs received weekly (4 patients biweekly) LDL apheresis for 3.5 +/- 2.5 years, after 0.5 - 3.0 years simvastatin in the maximally tolerable dose was added. Baseline LDL cholesterol concentration under diet and lipid lowering drugs in the patients receiving immunoadsorption, dextran sulfate adsorption and HELP apheresis was 265.4 +/- 54.9, 230.8 +/- 75.8 and 253.7 +/- 55.7 mg/dl, respectively. The calculated mean LDL cholesterol concentration of the last 5 treatments of the observation period was 123.7 +/- 22.8, 126.8 +/- 26.7 and 138.8 +/- 19.7 mg/dl, respectively. The evaluation of coronary angiographies revealed a definite regression of coronary lesions in 3 patients (8.8%), in all other patients there was a stop in progression. 3 patients died of cardiac complications during the observation period. We conclude that aggressive lipid lowering with combined LDL-apheresis and drugs can stabilize coronary atherosclerosis in most patients with refractory hypercholesterolemia.
