Abstract

Cardiovascular disease (CVD) is the major cause of death in renal transplant recipients (RTR). Several cohort studies have examined CVD in RTR, but none have addressed the development of congestive heart failure (CHF). CHF would hypothetically be a frequent and prognostically important event in RTR. A retrolective cohort study was, therefore, conducted in two Canadian centers to describe the incidence, risk factors for, and interrelationships between de novo CHF, de novo ischemic heart disease (IHD), and mortality in 638 consecutive adult RTR who were free of cardiac disease at 1 yr posttransplant. Detailed clinic and hospital records were available for 99% of patients. Median follow-up was 7 yr (range, 1 to 28 yr). De novo CHF occurred as frequently as de novo IHD (1.26 versus 1.22 events/100 patient-years, respectively) and appeared to carry a similar prognosis (relative risk for death, 1.78 [confidence interval, 1.21 to 2.61] for CHF versus 1.50 [1.05 to 2.13] for IHD). The incidence of CHF was considerably higher than that in the Framingham cohort, whereas the incidence of IHD was not, suggesting that renal transplantation might correspond more to a state of "accelerated heart failure" than to "accelerated atherosclerosis." Age, diabetes, gender, BP, and anemia were identified as independent risk factors for de novo CHF, whereas age, diabetes, gender, BP, and rejection were independent risk factors for de novo IHD. Optimal strategies for treatment of BP and anemia in RTR will need to be determined in randomized controlled trials.
