Abstract

In several studies, patients with CKD seemed to be at greater risk for dying from cardiovascular disease (CVD) than reaching ESRD. The purpose of this study was to compare incident ESRD rates with rates of total mortality, CVD death, and a CVD composite (CVD mortality and CVD hospitalization) among participants who had hypertensive nephrosclerosis and were enrolled in the African American Study of Kidney Disease and Hypertension (AASK). The study period included the AASK trial phase (1996 through 2001) and a subsequent cohort phase (2002 through 2007). The AASK enrolled 1094 participants. Of the 764 participants who completed the trial phase without an event, 691 (90%) enrolled in the cohort phase. During 11 years of follow-up, there were 59 CVD-related deaths and 118 non-CVD-related deaths. The rate of ESRD (3.9/100 patient-years) was significantly higher than the rates of total mortality (2.2/100 patient-years), CVD mortality (0.8/100 patient-years), and the CVD composite (3.2/100 patient-years). The incidence rate ratio of ESRD to CVD mortality was 5.0. The rate of ESRD consistently exceeded the various mortality rates across most of the subgroups defined by age, gender, income, education, previous CVD, baseline urine protein excretion, and baseline estimated GFR. In conclusion, AASK participants were more likely to reach ESRD than to die.
