Prognostic value of gated SPECT after reperfusion for acute myocardial infarction.
INTRODUCTION Myocardial reperfusion during the course of an acute myocardial infarction improves patients' short- and long-term prognosis; coronary blood flow is successfully re-established while preserving a large amount of at-risk muscle. Clinical evolution, however, varies. Presence of residual ischemia or viable myocardial tissue affects a patient's prognosis. Assessment by noninvasive meth...
متن کاملThe prognostic value of stress/rest gated myocardial perfusion SPECT in patients with known or suspected coronary artery disease
Introduction:Gated myocardial perfusion SPECT has diagnostic and prognostic values in coronary artery disease (CAD). We tried to determine prognostic values of the left ventricular perfusion & functional indices as well as transient left ventricular dilation (TID) derived from gated myocardial perfusion SPECT. Methods: 1820patients who underwent gated myo...
متن کاملThe value of the Gated 99mTc-MIBI SPECT in differentiation of fixed myocardial lesions [Persian]
Fixed myocardial defects in both stress and rest images, could be artifactual as a result of soft tissue attenuation. To increase specificity and identify the false positive results, we used gated technique to evaluate the wall motion and wall thickening as an index to differentiate real ischemic lesions from artifactual defects. 93 patients were studied. In 46 patients (48.8%) fixed perf...
متن کاملShort- and long-term clinical outcome after Q wave and non-Q wave myocardial infarction in a large patient population.
Prognosis for patients with non-Q wave myocardial infarction is controversial although a number of studies have shown a less favorable outlook after hospital discharge for patients with non-Q wave than for those with Q wave infarction. Therefore, the in-hospital and 1-year prognosis was investigated in a sufficiently large patient population (n = 2,024) to allow stratification by subgroups, in ...
متن کاملNon-Q wave myocardial infarction. Pathophysiology and prognostic implications.
Non-Q wave myocardial infarctions, also known as nontransmural myocardial infarctions or subendocardial myocardial infarctions, have been managed as "mild" coronary events in the past. Substantial evidence now requires modification of this approach. Because of their tendency to be associated with modest cardiac enzyme level elevations, non-Q wave infarcts often result in a favorable early or in...
