Prevalence of coronary atherosclerosis, evaluated from multislice tomography, in hypertensive afro descendants

The occurrence of atherosclerosis and associated factors in different Brazilian ethnic groups, especially among Afrodescendants, is not yet well established. To determine the prevalence and factors associated with coronary atherosclerosis among hypertensive Afrodescendants of Quilombola communities.The study evaluated 138 hypertensive individuals from the PREVRENAL study, a population-based cohort that evaluated Afrodescendants from 32 remaining Quilombola communities in the State of Maranhão. The coronary calcification score was obtained by non-contrast computed tomography. Clinical and laboratory data were collected from the PREVRENAL database. To evaluate the factors associated with the occurrence of atherosclerosis, the Poisson model with robust variance was adjusted. The data were processed in Stata 12.0 software. Among the individuals, 64.49% were female; the mean age was 60.93 (±12.25) years; 15.22% diabetics, 21.74% smokers and 21.74% reported alcohol consumption; 7.97% had GFR <60mL/min/1.73m², 22.46% albuminuria, 8.70% ultrasensitive C-reactive protein >1mg/dL, 20.29% mixed hyperlipidemia and 44.93% low HDL. There were 39.13% of patients with CCS>0. In the multivariate model, CCS was associated with: age > 60 years (PR 3.25, p-value=0.001), uric acid (PR=1.98, p-value=0.001). The prevalence of coronary calcification was significant in the group evaluated and was associated with age and uric acid.
