Abstrakt: Background: Many reports in the literature have found the use of invasive cardiac procedures in black patients to be less common than in white patients. These reports tend to have small numbers of black patients compared with white patients or rely on the information contained in claims or administrative data.
Methods and Results: Cardiac catheterization reports were reviewed in a Veterans Administration hospital that serves a large number of black patients. After review of the medical histories and hemodynamic and angiographic findings in 726 black and 734 white male veterans, data were collected to determine recommended and actual therapy. Death was assessed after a 4- to 10-year follow-up period. White patients were more likely to have significant coronary artery lesions than black patients. Multivariate analysis showed that the likelihood of patients actually having percutaneous transluminal coronary angioplasty or coronary artery bypass surgery did not differ by ethnicity when controlling for disease extent or severity. Coronary artery bypass surgery was associated with decreased mortality rates for both black and white patients. Although short-term death in blacks was not different from whites, blacks had an increased long-term risk for death.
Conclusions: After coronary angiography, black veterans and white veterans appear to undergo revascularization procedures related to the severity of disease. The decreased long-term life expectancy of black men as compared with whites is not necessarily explained by the presence of or treatment for coronary artery disease in this population.
