LVEF predicts one-year mortality after STEMI

Among 3197 patients with an acute ST elevation myocardial infarction (STEMI) who were treated with thrombolytic therapy in the TIMI II trial, the one-year mortality correlated with the resting left ventricular ejection fraction (LVEF) measured by radionuclide ventriculography obtained within 14 days of the event. The mortality was highest in patients with an LVEF <30 percent (9.9 percent). Patients not undergoing study for any reason had an intermediate mortality of 6.6 percent.
