title: Bimodal distribution of major cardiovascular events in kidney allograft recipients.
abstract: Cardiovascular disease (CVD) is the major cause of death after renal transplantation. We have retrospectively analyzed the incidence and the time of appearance of CVD among 870 consecutive cadaveric kidney transplant recipients, including 143 patients (16.5%) who experienced a fatal or nonfatal event after transplantation. Seventy-four recipients (54%) showed a fatal CVD. Studying the various manifestations, we observed a higher frequency of cardiac events (59% of ischemic heart disease), with 15% cerebrovascular disease and 22% peripheral vascular or aortic disease. In our group, CVDs were distributed in a bimodal manner, with a higher incidence in the first posttransplantation year and a late cluster of CVD at 8 years posttransplantation. The risk of death (hazard function) for CVD increased dramatically during the 8th year after transplantation. This trend of CVD after kidney transplantation may be explained by inadequate evaluation and management of CVD risk factors during waiting list time and, after transplantation, by the cumulative effects of traditional and nontraditional risk factors.
