Detection of coronary artery disease in diabetic hypertensive patients using conventional transthoratic echocardiography at rest

To investigate the usefulness of conventional transthoratic echocardiography in identifying coronary artery disease (CAD) in diabetic hypertensive patients, transthoratic echocardiography and coronary angiography were performed in 122 diabetic hypertensive patients with suspected CAD. Correlation analysis, multivariate analysis and receiver operating characteristic curve (ROC) analysis were done. Diabetic hypertensive patients with CAD had significantly smaller coronary sinus diameter (Dcs), less velocity time integral (VTI), less coronary sinus flow (Flow) and less Flow divided by left ventricular mass (Flow/LVM) at rest versus normal participants ( P
