In a study of 1194 patients with an acute ST segment elevation myocardial infarction (STEMI) treated with thrombolysis, the resting left ventricular ejection fraction (LVEF) measured by radionuclide angiography (RNA) was a powerful predictor of six-month mortality. The highest risk group was those with an LVEF <30 percent.
