An evaluation of the prognostic indices in acute myocardial infarction

A prospective study of hundred patients of acute myocardial infarction admitted in the Intensive Cardiac Care Unit was carried out. The prognosis of each patient, immediate and delayed morta­lity, were assessed on admission by the coronary prognostic indices (C.P.I.) formulated by Peel, Norris and Chapman. The merits and drawbacks of each coronary prognostic index system are discussed. It is felt that the coronary prognostic index would be more accurate if a higher score is given to precursor, life threatening arrhy­thmias, and conduction defects, and the prognostic index is calculat­ed daily during the stay in the I.C.C.U.
