One hundred Patients with different types of acute MI were studied. Inferior MI was the least with short term mortality, 6.6%, while it was 14.8% and 2.5% in anterior MI and combined MI respectively.
Pump failure was 13.3%[rho 0.05] in inferior MI versus 66.6% [rho 0.05] and 75 [rho 0.005] in anterior and combined MI. Cardiogenic shock occurred in 7.6% in inferior MI versus 14.8% and 12.5% in anterior and combined MI respectively. In 86 patients with transmural MI pump failure was nearly similar to the 16 patients with non transmural MI [51.1% vs 57.1%] . Mortality was 11.1% vs 28.5% in both transmural and non transmural MI. The incidence of tachyarrhythmias was less in non transmural than transmural MI. PACs were the commonest arrhythmias occurred in anterior MI [8 1.4%] while in combined MI [62.5] and in inferior MI [46%] . Next in frequency was sinus tachycardia. All patients who developed pump failure, had sinus tachycardia during their course. Also ventricular tachyarrhythmias occurred with highest incidence in anterior MI [40.7%] while in combind Ml [25%] and in inferior MI [20%] . AF was the most encountered supra ventricular tachyarrhythmia.8 patients with AF were in LVF, four of them died. Our results showed that AF affected short term mortality and morbidity. Bradyarrhythmias occurred mostly in inferior MI, with sinus bradycardia being the commonest. The extent of MI [judged by peak CPK did not affect significantly the morbidity and mortality]
