the myocardial perfusion scintigraphy in asymptomatic diabetic patients

introduction: asymptomatic diabetic patients are at increased risk of cardiovascular complications. myocardial perfusion scan may be effective in risk evaluation in this population. methods: 106 asymptomatic diabetic patients (age: min: 37, max: 82, mean: 57.73±8.88), including 56 females (52.8%) and 50 males (47.2%) were enrolled in the study. myocardial perfusion scintigraphy was performed by gated single photon emission computed tomography (gated-spect) method. perfusion and function status was evaluated by qualitative and semi-quantitative parameters. results: by visual analysis totally 40 out of 106 patients (37.7%) showed abnormal scan. from which, 26(24.5%) showed involvement in one, 13(12.3%) in two, and 1(0.9%) in all three vessel territories. by semi-quantitative method, from 103 patients, 28 (27.2%) were abnormal and 75 (72.8%) were normal. from all the asymptomatic diabetic patients, 11 patients (10.4%) had dilated left ventricles. transient ischemic dilation (tid) was noted in 10 patients (9.4%), and transient right ventricle visualization in 7 patients (6.6%). heart failure (ef
