Abstract

Residual myocardial ischemia and left ventricular systolic dysfunction are the major determinants of a patient's prognosis after myocardial infarction. Therefore, left ventricular function and residual ischemia should be evaluated in all patients before release. Coronary angiography should be performed in uncomplicated myocardial infarction patients with significant ischemia or left ventricular dysfunction. In these cases angiography must be performed to determine if coronary arteries are suitable for revascularization before performing a test of myocardial viability. Several radionuclide approaches are currently available for the clinical evaluation of patients after myocardial infarction. There is growing and consistent evidence that the scintigraphic approaches are the most sensitive technique to investigate the presence of ischemia or tissue viability and also to provide an accurate and reproducible evaluation of the left ventricular function. Most importantly, radionuclide evaluation in these patients provide valuable prognostic information. However, the number of patients with malignant arrhythmia's detected with routine evaluation is lower at this time. In several reports neuroadrenergic imaging evaluation with I-123-MIB...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
