Myocardial mitochondrial dysfunction is the main cause of various heart diseases such as myocardial infarction, myocarditis, hypertrophic cardiomyopathy, and heart failure. In recent years, many studies have confirmed that traditional Chinese medicine(TCM) can be used to improve myocardial mitochondrial function and treat heart disease. The purpose of this review was to analyze the regulatory mechanism of myocardial mitochondrial function by summarizing the effect of TCM on cardiovascular disease.展开更多
