A Clinical Analysis of 90 Cases of Acute Myocardial Infarction / 第三军医大学学报

ABSTRACT

This paper is to report a clinical analysis of 90 cases of acute myocar-dial infarction (AMI) admitted in the past 9 years. High incidence of AMI was found between the ages of 50 to 69 years. Infarction frequently occurred on the anterior interventricular septal part, lower part, and anterior ventricular part of the cardiac wall. AMI was complicated with cardiac arrhythmia in 84.4% of cases, with cardiac failure in 25.6%, and cardiogenic shock in 18.9%. UDT hemorrhage, ventricular aneurysm and interventricular septum rupture were also seen. 13 cases died in the acute phase due to pumping failure, 6 due to sudden cardiac standstill, 5 due to interventricular septum rupture, and 1 due to extra-cardiac cause. 77 cases were discharged after clinical recovery.63 cases were followed up from 5 months to 8 years. Among them, 4 cases died 1 to 2 years after the onset of AMI, and 1 case 4 years after. 58 cases are living up to present. Long term prognosis is not closely related to the location and extent of the infarction.
