A simple scoring system based on clinical variables available on admission can be used to stratify patients by risk shortly after presentation.
Patient selection:
(1) Patients with their first acute inferior myocardial infarction.
(2) Patients in cardiogenic shock (Killip class 4) excluded.
Risk Factors:
(1) age in years
(2) history of previous angina
(3) Killip class on admission
(4) glucose on admission
