Prediction of Severity of Coronary Stenosis in the Absence of Infarction by Tissue Doppler Imaging and Conventional Echocardiography at Rest

Prediction of Severity of Coronary Stenosis in the Absence of Infarction by Tissue Doppler Imaging and Conventional Echocardiography at Rest

Tissue Doppler imaging (TDI) is a relatively new method that measures regional myocardial velocities on the basis of color Doppler imaging. The aim of this study was to investigate both systolic and diastolic parameters to diagnose coronary stenosis at rest. We examined 73 patients without previous...
