Functional and anatomic correlates of asymptomatic and symptomatic stress responses in patients free from prior infarction

To identify the noninvasive indices most likely to detect asymptomatic myocardial ischemia or its consequences we evaluated exercise induced changes in electrocardiographic (ECG) ST segments radionuclide left ventricular ejection dynamics and doppler assessments of ascending aortic flow in patients free from prior myocardial infarction referred for coronary angiography
