Abstract
Familial hypercholesterolemia is characterized by a high plasma level of cholesterol and is frequently associated with rapidly progressing coronary heart disease. The internal thoracic artery is recognized as the conduit of choice for coronary artery bypass grafting. This study was performed to determine whether multiple arterial grafting was associated or not with additional benefits for patients with familial hypercholesterolemia. Between June 1980 and March 1998, 95 patients with familial hypercholesterolemia underwent a total of 103 coronary artery bypass procedures with one hospital death. The patients were divided into 3 groups according to the type of bypass graft Group 1 included 31 patients with only saphenous vein grafts; Group 2, 48 patients with one arterial graft and supplemental vein grafts; and Group 3, 24 patients with multiple arterial grafts. The overall actuarial suvival rate was 90.9% at 10 years and 81.8% at 18 years. The overall actuarial freedom from recurrent angina was 68.9% at 10 years and 55.8% at 16 years. The actuarial survival rate in group 2 was higher than that in Group 1 (p < 0.05). There was no difference in the actuarial survival or in the freedom from cardiac events between Group 2 and Group 3. Single arterial grafting improved the long-term survival in patients with familial hypercholesterolemia. However, no additional benefit from multiple arterial grafting was identified.
