Dobutamine stress 99mTc-tetrofosmin quantitative gated SPECT predicts improvement of cardiac function after carvedilol treatment in patients with dilated cardiomyopathy.
UNLABELLED We evaluated whether dobutamine stress (99m)Tc-tetrofosmin quantitative gated SPECT (D-QGS) could predict improvement of cardiac function by carvedilol therapy in patients with dilated cardiomyopathy (DCM). METHODS The study included 30 patients with idiopathic DCM and a left ventricular ejection fraction (LVEF) of <45%. D-QGS was performed in all patients to measure LVEF at rest a...
متن کاملPrognostic stratification using dobutamine stress 99mTc-tetrofosmin myocardial perfusion SPECT in elderly patients unable to perform exercise testing.
UNLABELLED Information on the prognostic value of noninvasive stress imaging techniques in the elderly is relatively scarce. This study assessed the prognostic value of dobutamine stress (99m)Tc-tetrofosmin SPECT for the prediction of mortality and cardiac events in elderly patients. METHODS Clinical information and SPECT results were analyzed for 272 consecutive patients > or = 65 y old (mea...
متن کاملEvaluation of cardiovascular complications with 99mTc tetrofosmin gated myocardial perfusion scintigraphy in patients with thalassemia major.
OBJECTIVE Iron overload limits the life expectancy of thalassaemic patients by causing cardiac toxicity. Iron also plays a catalytic role in the pathogenesis of atherosclerosis. The aim of this study was to evaluate the role of (99m)Tc Tetrofosmin gated myocardial perfusion scintigraphy (GMPS) in the detection of cardiac dysfunction in patients with thalassemia major. MATERIALS AND METHODS Fo...
متن کاملLeft ventricular mass index measured by quantitative gated myocardial SPECT with 99mTc-tetrofosmin: a comparison with echocardiography.
OBJECTIVE Left ventricular mass is an important determinant of diagnosis and prognosis in patients with heart disease. The aim of the present study was to validate measurement of the left ventricular mass index (LVMI) by quantitative gated myocardial SPECT (QGS) with 99mTc-tetrofosmin by comparing it with echocardiography. METHODS QGS and M-mode echocardiography (Echo) were performed within o...
