To analyze the correlation between myocardial ischemia and carotid atherosclerosis in hypertensive patients. The clinical data were collected from 85 hospitalized hypertensive patients admitted between May 2005 and September 2008 without the complication of coronary artery disease as confirmed by cardiac computed tomographic angiography (CTA). According to the results of treadmill exercise test, the patients were divided myocardial ischemia group and ischemia-free group. Univariate and multivariate analyses were used to screen the risk factors of myocardial ischemia. The correlations were analyzed between myocardial ischemia, common carotid artery intima-media thickness (IMT), Crouse score of the carotid plaque, thickness of the intraventricular septum and left artrium. The receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity of IMT and Crouse score in predicting the presence of myocardial ischemia in hypertensive patients. Carotid plaque formation was identifie
