Prognostic 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 کاملTime course evaluation of myocardial perfusion after reperfusion therapy by 99mTc-tetrofosmin SPECT in patients with acute myocardial infarction.
UNLABELLED Myocardial perfusion imaging with 99mTc-labeled agents immediately after reperfusion therapy can underestimate myocardial salvage. It is also conceivable that delayed imaging is useful for assessing the risk area. However, to our knowledge, very few studies have sequentially evaluated these image changes. We conducted 99mTc-tetrofosmin (TF) and 123I-beta-methyl-p-iodophenylpentadecan...
متن کاملPrognostic stratification of obese patients by stress 99mTc-tetrofosmin myocardial perfusion imaging.
UNLABELLED Obesity is a major heath problem associated with increased cardiovascular mortality. There are currently no data to support a role for stress imaging techniques in the risk stratification of obese patients. The aim of this study was to assess the independent value of stress 99mTc-tetrofosmin SPECT in predicting mortality and hard cardiac events in obese patients. METHODS We studied...
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 کاملCardiac stress imaging for the prediction of very long-term outcomes: Dobutamine stress echocardiography or dobutamine 99mTc-sestamibi SPECT?
BACKGROUND Both dobutamine stress echocardiography (DSE) and myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) are frequently used for cardiac risk stratification. The long-term relative prognostic value of these modalities has not been studied. Therefore, this study evaluated the long-term prognostic value of DSE compared to MPI in patients unable to p...
