RESUMO
INTRODUCTION: Pretransplant cardiovascular risk may be amplified after renal transplant, but little is known about its impact on graft outcomes. RESEARCH QUESTION: The purpose of this study was to determine if pretransplant cardiovascular risk was associated with graft outcomes. DESIGN: This retrospective study included deceased-donor renal transplant recipients from 2010-2015. Atherosclerotic cardiovascular disease risk for patients without prior disease was calculated and patients were categorized into high (score >20%), intermediate (7.5-20%), and low risk (<7.5%). Patients with and without prior cardiovascular disease were also compared. The main endpoint was graft failure at 3-years post-transplant. Other outcomes included major adverse cardiovascular events, biopsy-proven rejection, and mortality. RESULTS: In patients without prior atherosclerotic cardiovascular disease (N = 115), graft failure rates (4.5% vs 11.3% vs 12.5%; (P = 0.64) and major adverse cardiovascular events (9.1% vs 13.2% vs 5.0%; P = 0.52) were similar in the high, intermediate, and low risk groups. In those with prior disease (N = 220), rates of primary nonfunction (6.8% vs 1.7%; P = 0.04), major adverse cardiovascular events (7.3% vs 2.6%; P = 0.01), and heart failure (10.9% vs 3.5%; P = 0.02) were higher than those without cardiovascular; rates of major adverse cardiovascular events and heart failure were insignificant after adjusting for age, gender, and race. Other outcomes were not different. Outcomes did not differ based on pretransplant cardiovascular risk. DISCUSSION: Pretransplant atherosclerotic cardiovascular disease was associated with increased early graft failure but similar outcomes at 3-years, suggesting cardiac risk alone should not exclude transplantation.
