The prognostic value of estimating stroke volume before and after exercise during treadmill stress echocardiography

Background Stress echocardiography (SE) is an established technique for assessment of coronary artery disease (CAD) which is difficult to perform and interpret. Left ventricular stroke volume (SV) is readily estimated with Doppler echocardiography. It can be affected by myocardial ischemia, with possible adjunctive value during SE. Methods Patients underwent Bruce protocol SE with SV estimated before and after maximal treadmill exertion post...
