[Clinical features of acute myocardial infarction in the young and middle-aged patients: analysis of 68 cases of coronary artery angiography].
OBJECTIVE
This study was to evaluate the clinical features of acute myocardial infarction (AMI) in young and middle-aged patients.


METHODS
Eighty-seven patients were classified into two groups according to the age. Among them, 61 patients were 60 years old and above, 26 patients below 50 year old. Selective coronary artery angiography was performed on 68 cases and a scoring method which reflects the extent of narrowing of coronary artery was also used.


RESULTS
The older group had more risk factors than the young group. The angina pectoris in the young group was less than the older group. The incidence of acute heart failure in the young group was higher than the older group. The mortality of both two groups had no significant differences.


CONCLUSIONS
The high risk of AMI in the young and middle-aged patients should be paid more attention in the clinic.
