Coronary Angiographic Findings and Risk Factors in Acute Myocardial Infarction Patients before after Age 50

摘要

Background A number of studies in western countries have shown that coronary artery disease(CAD) and younger patients with acute myocardial infarction(AMI) is less extensive but more. closely related to cigarette smoking. However, there are some similarities between the characteristics of the CAD and the risk factors analyzed by age subsets in patients with AMI in Korea. Methods Pre-discharge coronary angiograms and risk factors in 194 patients with first AMI(male/female : 154/40,79.4%/20.6%) were analyzed. A comparison was made between the lesion characteristics of the infarct related artery(IRA) and the CAD risk factors. Those under 49 years old (Group I, n=54, male/female : 50/4 : 92.6%/7.4%) and those over 50 years old ( Group II, n=140, male/female : 104/36 : 74.3%/25.7%). Results There are 54 and 140 patients in groups I and II respectively. 92% of group I and 74.1% of group II were male (p2and 0.54±0.80mm2, respectively, p Conclusion These findings reveal that coronary atherosclerotic lesions of IRA in patients with AMI in the younger age group are less severe. However, they are more closely related to cigarette smoking and alcohol intake, than cases in the older age group.
