In-hospital mortality after acute myocardial infarction [prospective study]

ABSTRACT

Eighty-five consecutive patients with acute myocardial infarction [AMI] [67 males and 18 females] were studied in Medical Unit-III, Allied Hospital Faisalabad during 1990-91 for assessment of in-hospital mortality. Mean age at the time of infarction was 54 years [25-90 years]. Sixty-five [78%] had Q-wave infarction while 19 [22%] had non Q-wave infarction. Overall in-hospital-mortality was 16.5%. Mortality was higher in males compared to females [22% vs 5.3%] and Q-wave infarction compared with non-Q-wave infarction [20% vs 5%]. Similarly in-hospital-mortality was higher in patients with inferior infarcts, those having reciprocal ECG changes, arrhythmias and relatively high cardiac enzymes. In-hospital mortality was significantly low in patients receiving thrombolytic therapy with streptokinase compared with patients on nitrates and heparin alone
