Based on clinical data available at hospital admission, it is possible to assess a patient's mortality risk in acute myocardial infarction.
Parameters:
(1) age in years
(2) location of the infarct
(3) ventricular function

prognostic index =
= 5.9019 - (0.0369 * (age in years)) - (0.5708 * (location)) - (0.8961 * (ventricular function))
Interpretation:
• prognostic index > 3: low risk, with mortality rate approximately 4%
• prognostic index > 1 to <= 3: intermediate risk, with mortality rate approximately 18%
• prognostic index <= 1: high risk, with mortality rate approximately 51%
