Prevalence of cardiovascular risk factors before kidney transplantation

Abstract

Context: Assessing the prevalence of cardiovascular risk factors is an essential step in developing risk profiles and individualizing interventions to reduce the cardiovascular morbidity and mortality of kidney transplant recipients.

Objective: To examine the prevalence of pretransplant modifiable, potentially modifiable, and nonmodifiable cardiovascular risk factors in patients who received kidney transplants between January 1, 1994, and December 31, 1996.

Design: An exploratory, retrospective nested case-control design was employed to assess pretransplant cardiovascular risk factors in kidney transplant recipients with documented posttransplant cardiovascular events (n = 12) and kidney transplant recipients with no documented posttransplant cardiovascular events (n = 66). Data were analyzed using frequencies, unpaired t tests, and chi 2 analyses.

Results: Significantly higher means of body mass index values greater than 25 kg/m2 (32.3 +/- 5.8 kg/m2 vs 28.8 +/- 3.4 kg/m2) and serum total cholesterol levels greater than 200 mg/dL (254.5 +/- 5.7 mg/dL vs 242.3 +/- 39.3 mg/dL) were noted in patients with documented cardiovascular events compared to those with no documented cardiovascular events, respectively. Diabetes was more prevalent in patients with documented cardiovascular events (33%); these patients were also predominantly African American men who had a higher prevalence of family and personal histories of cardiovascular disease (17% and 33%).
