Prevalence of moderate or severe left ventricular diastolic dysfunction in persons with suspected myocardial ischemia with and without an abnormal adenosine or exercise sestamibi stress test or coronary revascularization

Abstract

We investigated in 335 patients (mean age-63 year) with suspected myocardial ischemia the prevalence of moderate or severe left ventricular diastolic dysfunction (LVDD) in patients with an abnormal adenosine or exercise sestamibi stress test (SST) or prior coronary revascularization and in patients with a normal SST and no prior coronary revascularization. Moderate or severe LVDD was present in 117 of 142 patients (82%) with an abnormal SST or prior coronary revascularization and in 111 of 193 patients (58%) with a normal SST and no prior coronary revascularization (p < 0.001). Moderate or severe LVDD was present in 34 of 38 patients (89%) with an abnormal SST or prior coronary revascularization and an abnormal left ventricular ejection fraction (LVEF) and in 4 of 8 patients (50%) with a normal SST and no prior coronary revascularization and an abnormal LVEF (p < 0.01).
