Ethnic gap in coronary artery disease: comparison of the extent, severity, and risk factors in Arab and Jewish middle-aged women.

Abstract

The authors examined risk factors and extent of coronary artery disease (CAD) among Jewish and Arab women in Jerusalem, where Arab women were found to have worse outcome. All angiographically confirmed cases of CAD among women aged 45 to 65 years who were hospitalized during 1990 to 1995 consisted of 40 Arab and 179 Jewish patients. Arab women had more atypical clinical presentations (P<.0001) and more extensive CAD (P=.0016) despite younger age (53+/-3 vs 55+/-5 years; P<.0003) and lesser smoking (P<.0006). The Arab women, however, were more likely to be obese (80% vs 46%; P=.0002), be physically inactive (100% vs 89%; P=.0285), and have diabetes mellitus (73% vs 40%; P=.0004). Moreover, they were more likely to have 3 or more risk factors (45% vs 23%; P=.036). Thus, a combination of an atypical presentation and higher risk (ie, diabetes mellitus combined with hypertension and other risk factors) and much more extensive disease readily explains their worse outcome.
