African-American veterans may have lower incidence of coronary heart disease (CHD) and lower all-cause mortality than white veterans, according to a study published Sept. 18 in Circulation. These results are in contrast with the higher mortality experienced by African-Americans in the general population. The authors write that biological differences, overwhelmed by the socioeconomic disparities in the general population, may be a possible explanation for these racial discrepancies. They note that these genetic differences could affect other cardiovascular outcomes including a higher incidence of hypertension, more uncontrolled hypertension, and differences in central aortic blood pressure and prevalence of left ventricular hypertrophy in African-Americans.
