Acute Myocardial Infarction in Somdet Phraphutthalertla Hospital

Abstract

A retrospective study of acute myocardial infarction in Somdet Phraphutthalertla Hospital during January 1, 1995-December 31,1999. There were 72 cases with age ranging from 48 - 87 years and male to female ratio of 3.5 : 1. The sites of acute myocardial infarction were anterior wall (52.8%), inferior wall (37.5%), subendocardial (4%), both anterior and inferior walls (2.8%), lateral wall (1.4%) and posterior wall (1.4%). The most common incidence of supraventricular dysrhythmia was sinus tachycardia and the least was atrial flutter and junctional rhythm. The most common ventricular dysrhythmia was premature ventricular contraction (55.6%) and the least was accelerated idioventricular rhythm. The mortality rate was decreased from 18% (1995) to 12.3% (1999). It was probably due to our better care in our intensive care unit. The common cause of death was cardiogenic shock.
