Coronary Heart Disease Clinical Trial
Official title:
Peking University and University of Michigan- Study of Myocardial Infarction and Atherosclerosis
Coronary heart disease and myocardial infarction have become a major threat to the health of our people. Their incidence rate and mortality rate are still rising. Dyslipidemia is one of the important risk factors. However, little is known about the genetic information of myocardial infarction and dyslipidemia, especially in Chinese population. This project aims to identify new loci related to myocardial infarction and blood lipid level in Chinese population, compare these gene variations with 94 gene variations related to myocardial infarction and blood lipid level in European population, and extract gene variations related to myocardial infarction and blood lipid level in Chinese population. In this case-control study, 3998 blood samples and 702 new blood samples were collected from the sample bank of Peking University Third Hospital and first hospital, respectively. The blood samples were collected from Asian heart disease hospital, Taiyuan cardiovascular disease hospital, Beijing Third Hospital and Shijingshan community follow-up population According to the results of carotid ultrasound or treadmill exercise test, the samples were divided into myocardial infarction group and control group, and the corresponding blood lipid levels were collected. The samples were genotyped by the metabochip gene chip of Illumina company. The data were processed by the calling algorithm of BeadStudio Gentrain 1.0 and the GenoSNP software. The related genes of myocardial infarction were analyzed by logistic regression, and the related genes of blood lipid level were analyzed by linear regression.
Background: coronary heart disease and myocardial infarction have become a major disease threatening the health of our people. Their incidence rate and mortality rate are still rising. Dyslipidemia is one of the important risk factors. However, little is known about the genetic information of myocardial infarction and dyslipidemia, especially in Chinese population. Objective: to identify new loci related to myocardial infarction and blood lipid level in Chinese population, compare these gene variations with 94 gene variations related to myocardial infarction and blood lipid level in European population, and extract gene variations related to myocardial infarction and blood lipid level in Chinese population. Methods: This is a case-control study. 9498 blood samples and 702 new blood samples were collected from the sample bank of Peking University Third Hospital and first hospital respectively. The blood samples were collected from Asian heart disease hospital, Beijing Third Hospital and Shijingshan community follow-up population According to the results of carotid ultrasound or treadmill exercise test, the samples were divided into myocardial infarction group and control group, and the corresponding blood lipid levels were collected.
