ABSTRACT

Several radionuclide approaches are currently available fot he evaluation of left ventricular function in patients with coronary heart disease. There is growing and consistent evidence that the scintigraphic approaches provide an accurate and reproducible evaluation of left ventricular function. Most importantly, radionuclide evaluation in these patients provide valuable prognostic information. Equilibrium radionuclide angiography is the most reproducible, accurate, and simple method for noninvasively assessing left ventricular ejection fraction. This technique is now most often used for serial assessment of LVEF, for regional wall motion abnormalities in patients with recent or old myocardial infarction, and for evaluation of inotropic reserve in patients with congestive heart failure. Recently, it has been shown that intraventricular dissynchrony evaluated with phase analysis of radionuclide angiography is an independent predictor of sudden death in patients with heart failure.
