    Abstract:
    Twenty-five heterozygous familial hypercholesterolemic patients treated with LDL-apheresis and drugs and 11 patients treated with drugs underwent follow-up angiography 2.3 years later. One-hundred thirteen lesions were measured by quantitative angiography. Mean LDL-cholesterol levels during the trial were 140 +/- 34 mg/dl in the apheresis group and 170 +/- 58 mg/dl (P < 0.05) in the control group. The mean changes in minimal lumen diameter of lesions were +0.19 +/- 0.30 mm (improved) in the apheresis group (n = 76) and -0.44 +/- 0.40 mm (worsened) in the control group (n = 37) (P < 0.0001). When progression and regression were defined as a change in minimal lumen diameter of +/- 0.67 mm, in the apheresis group, two (8%) patients had progression, 19 (76%) stayed unchanged and four (16%) had regression, but in the control group seven (64%) patients had progression and four (36%) stayed unchanged. The frequency of regression or no change was significantly higher in the apheresis group than in the control group (P < 0.004). Intensive cholesterol lowering therapy with LDL-apheresis and lipid lowering drugs can achieve a substantial decrease in LDL-cholesterol levels to induce regression of coronary lesions in familial hypercholesterolemic patients with advanced coronary artery disease.
