Objective To summarize and analyze clinical characteristics of patients with acute myocardial infarction(AMI)admitted in the Department of Cardiology from Jan of 1998 to Feb of 2001 as to get much improvement on diagnosis and treatment of AMI.

Ⅲ degree atrioventricular block was about 34%(12/35) in patients with AIMI. There were 86%(83/95) of survival rate and about 7%(7/95) of mortality in 95 patients. Conclusions More patients with AMI occured in male of over 40 years old. Chest pain was main manifestation in most AMI patients and some patients were complicated with heart failure,arrhythmia and other complications.
