Strain and Strain Rate Echocardiography and Coronary Artery Disease





Doppler-derived and 2D echocardiographic–derived myocardial strain imaging represent exciting advances in the field of noninvasive cardiac imaging. Strain and SR are sensitive (detect early disease), correlate well with other measures of cardiac function, and detect changes in myocardial contractility, both normal and abnormal, across a wide range of ischemic syndromes. They provide novel insights into the complex deformations of the left ventricle and appear likely to enhance detection of coronary artery disease and viable myocardium and predict the sequelae of myocardial infarction, the response to reperfusion, and prognosis.
