Introduction: We aimed to assess whether the vasodilator effect of oral dipyridamole on the left ventricular systolic function in patients with suspected CAD is different from that of intravenous (IV) dipyridamole using Tc-99m MIBI myocardial perfusion gated SPECT. Methods: Eighty-nine patients (17 M / 72 W; 61 ± 10 years) were enrolled in this study. The patients underwent a dipyridamole stre...

It is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. Having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ECG-Gated is an appropriate method for this purpose. The aim of this study was to compare the results of myocardial perfu...

conclusions no significant variance was observed among patients underwent for cardiac catheterization, stemi, nstemi, unstable angina, and atrial fibrillation with respect to ft4, ft3, and tsh levels during coronary care unit hospitalization based on their profile data. results excluding those taking thyroid hormone preparations, 76.7% of patients admitted with acute coronary heart disease (st-...

spontaneous coronary artery dissection (scad) is a rare condition that can result in unstable angina, acute myocardial infarction, and sudden death. this condition may occur particularly in women during late pregnancy and in the postpartum period. we present the case of a 33-year-old african american woman, who had spontaneous left anterior descending coronary artery (lad) dissection two weeks ...

BACKGROUND Patients with aortic stenosis have a period of compensated left ventricular hypertrophy but may eventually develop congestive heart failure. Previous experimental studies showed either normal myocardial contractility in mild short-term pressure overload or myocardial dysfunction with severe pressure overload. Transition from compensated left ventricular hypertrophy to myocardial dysf...
