Serum levels of LP (a) with LDL, VLDL, and HDL in 218 hospitalized cases with AMI or UA

Background: Unstable angina and myocardial infarction are developed due to atherosclerosis of coronary arteries. At present, cholestrol, triglyceride, and lipoproteins are the most common risk factors of death. The purpose of this study was to assess the serum levels of LP (a), LDL-C, VLDL-C, HDL-C in cases of unstable angina and myocardial infarction. Methods: This study was conducted to compare the serum level of LP (a) with LDL-C, VLDL-C, HDL-C on 218 cases of unstable angina and myocardial infarction who were admitted at the Department of Cardiology, Babol Medical University from October 2004 to October 2005. Serum levels of LP (a) with LDL, VLDL, and HDL in these cases were measured and recorded. Results: Two-hundred-eighteen cases (188 unstable angina, 30 with myocardial infarction) were studied. There were significant differences between serum levels of LDL-C LP (a), cholesterol, HDL-C, in patients with unstable angina and myocardial infarction, but regarding VLDL-C or TG the differences were not significant. Conclusion: The results show that there is a relation to high levels of LDL-C, LP (a), cholesterol, HDL-C, and HDL-C with unstable angina and myocardial infarction. The level of LP (a) in MI subjects was higher than that of unstable angina.
