[Analysis on characteristics and risk factors of acute myocardial infarction in younger adults].
OBJECTIVE
To investigate the risk factors and characteristics related to acute myocardial infarction (AMI) in younger adults.


METHODS
Clinical data were analyzed in 55 patients under 40 years old with AMI and compared with 1,097 controls of older age group (> or = 40 years).


RESULTS
Results showed that the family history of coronary heart disease, smoking and alcohol intake were more frequently seen in younger age group than those in control group with odds ratios OR = 1.4, OR = 1.6 and OR = 1.6, respectively. Younger age group had a higher rate of noticeable inducing cause and the major causes were exhaustion and physically over-hurdened. A higher percentage of typical chest pain was found in younger patients.


CONCLUSIONS
Smoking, alcohol drinking and genetic factor made up major risk factors of coronary heart disease in younger adults in this study, however reducing the amount of smoking and alcohol drinking, prevention of fatigue and over excitement might have some preventive impact on the prevalence of AMI in younger population.
