CARDIOLOGY

Recall the prognostic indicators that influence survival following myocardial infarction.

Explanation:

LV ejection fraction is the most important prognostic indicator.

Another important indicator is presence of ischemia in an area other than the infarct area(ischemia at a distance).

Ventricular arrhythmias within 48 hours of the MI do not impact the outcome but those later than that do.
