Key result
Rest left ventricular ejection fraction strongly predicted 1-year mortality after thrombolytic therapy for acute myocardial infarction, with a 9.9% mortality rate in patients with LVEF <30%.
Why the study?
Does radionuclide rest and exercise left ventricular ejection fraction predict 1-year mortality in patients after thrombolytic therapy for acute myocardial infarction?
Observational

Rest LVEF is an important prognostic index in patients receiving thrombolytic therapy for acute myocardial infarction, while exercise LVEF does not provide appreciable additional prognostic data.
No takes yet. Share an insight, caveat, or question.
Rest LVEF supports post-thrombolysis risk stratification in AMI; extends prethrombolytic prognostic models but leaves open confirmation in randomized cohorts.
Zaret et al. (1995) conducted an observational in Acute myocardial infarction. Radionuclide left ventricular ejection fraction at rest and exercise vs. Prethrombolytic era patients (Multicenter Postinfarction Research Group) was evaluated on 1-year all-cause and cardiac mortality. Rest left ventricular ejection fraction strongly predicted 1-year mortality after thrombolytic therapy for acute myocardial infarction, with a 9.9% mortality rate in patients with LVEF <30%.
