Abstract

Coronary artery disease after cardiac transplantation is a major obstacle to long-term survival. The development and progression of coronary artery disease after cardiac transplantation was analyzed in 217 consecutive patients undergoing transplantation. The actuarial freedom from any coronary artery disease (by angiography or autopsy) was 81% at 2 years and 20% at 8 years after transplantation. Coronary artery disease was more prevalent in male than female patients (30% versus 50% free of coronary artery disease at 5 years, p = 0.01). By multivariable analysis, pretransplantation risk factors identified for coronary artery disease included pretransplantation positive cytomegalovirus serologic status of the recipient ( p = 0.002) and older donor age (p = 0.07). Progression of coronary artery disease was variable in both time of onset and rate. Earlier detection did not result in more rapid progression. Coronary events severe enough for retransplantation ( n = 8) and/or death from coronary artery disease ( n = 9) occurred in 15 patients, of whom four underwent retransplantation. The actuarial freedom from coronary events was 88% at 5 years and 79% at 8 years. By multivariable analysis, only male recipient ( p = 0.05) was a risk factor for coronary events. Seven of the 15 patients (47%) with coronary events died suddenly of coronary artery disease without prior angiographic evidence of severe coronary disease. Coronary artery disease is progressive. Improved surveillance methods are required to detect the disease and institute timely intervention to prevent the occurrence of unanticipated death. (J THORAC CARDIOVASC SURG 1995;109:1081-9).
