Collect exosomes in peripheral blood of patients with myocardial infarction, compare the expression of miRNA with healthy volunteers, find out the miRNAs with significant differences, and explore its relationship with the development of myocardial infarction.
The aim of this study is to determine the miRNA expression profile in peripheral blood exosomes of patients with myocardial infarction and to investigate its relationship with myocardial infarction.
