Key result
Persistently low left ventricular ejection fraction after a first myocardial infarction was associated with further cardiac failure, and a fall in EF on exercise was associated with subsequent angina.

Does radionuclide ventriculography-derived LVEF predict future cardiac failure or angina in patients after their first myocardial infarction?
Radionuclide ventriculography-derived LVEF after a first myocardial infarction provides important prognostic information, with persistently low EF predicting heart failure and failure to increase EF on exercise predicting angina.
Dewhurst et al. (1980) conducted a cohort in Myocardial infarction (n=50). Low left ventricular ejection fraction (assessed by radionuclide ventriculography) vs. Normal or improving left ventricular ejection fraction was evaluated on Cardiac failure and angina. Persistently low left ventricular ejection fraction after a first myocardial infarction was associated with further cardiac failure, and a fall in EF on exercise was associated with subsequent angina.
