- Abstract
- Background Although the risk factors of coronary heart disease have been analyzed frequently in Korea, There is no data about
differences between acute myocardial infarction and angina pectoris in their risk factors. There would be some differences of risk
factors between acute myocardial infarction and angina pectoris. We analyzed baseline characteristics, risk factors among
patients who have undergone coronary angiography (CAG). Method A total of 1046 patients (621 males and 425 females) who
have undergone a coronary angiography (CAG) from 1st January 2000 to 31st December 2003 were analyzed retrospectively.
According to the diagnosis, the patients were classified into 2 groups, myocardial infarction and angina pectoris. The analysis
involved diagnosis distribution, the differances of risk factors, coronary angiographic characteristics of acute myocardial
infarction and angina pectoris. Result The serum homocysteine, the prevalence of history of more than one pack smoking per
day were significantly higher in myocardial infarction group than angina pectoris group ( OR 1.059, 95% CI 1.000˜1.120
p=0.049,OR 3.471, 95%CI 1.636˜ 7.362, p=0.002 respectively ). However the serum triglyceride level were significantly lower in
acute myocardial infarction group than angina pectoris group (OR 0.996, 95% CI 0.994˜ 0.999, p=0.016 ). The coronary
angiographic findings were more severe in acute myocardial infarction group than angina pectoris group. Conclusion Serum
triglyceride level, homocysteine level, history of more than one pack smoking per day history and more severe coronary
angiographic findings are significant differences between acute myocardial infarction and angina pectoris. Key words: acute
myocardial infarction, angina pectoris, risk factors
