This study was designed to characterize the changes in the peak systolic longitudinal, circumferential and radial strains by using 2-D strain echocardiography in patients with coronary artery stenosis without segmental wall motion abnormalities on conventional 2-D echocardiography. 2D strain echocardiography was performed in 44 patients with different degrees of coronary artery stenosis. Myocardial longitudinal, circumferential and radial strain profiles were obtained and peak systolic strain values were measured. The peak systolic longitudinal strain was significantly reduced in myocardial segments subtended by coronary arteries with greater than 75% stenosis when compared with those subtended by coronary artery with less than 75% stenosis and those in control. Sensitivity and specificity were 74% and 72%, respectively, for peak systolic longitudinal strain to predict segments subtended by coronary arteries with greater than 75% stenosis (cutoff value--17.7%; area under the receiver operating characteristic curve, 0.825). There were no significant differences in circumferential and radial strains among myocardial segments subtended by coronary arteries with greater than 75% stenosis and those with less than 75% stenosis and in control. In conclusion, our study suggests that analysis of long-axis cardiac function by using the 2-D strain echocardiography may help to identify the myocardial segments subtended by coronary arteries with severe stenosis.
