Résumé
Diabetic cardiomyopathy, one of the cardiovascular complications of diabetes, is characterized by cardiac systolic and diastolic dysfunction at the early stage, which can later develop into heart failure. Due to the high incidence and mortality, it has been a hot topic in recent years. The pathogenesis of diabetic cardiomyopathy is complicated. It has been proved related to abnormal glucose and lipid metabolism, cardiac insulin resistance, mitochondrial dysfunction, abnormal calcium homeostasis, activation of renin-angiotensin-aldosterone system, increased oxidative stress, endoplasmic reticulum stress, inflammation, autophagy, and so on. The specific pathogenesis remains unclear. Currently, the diabetic cardiomyopathy is mainly tackled with both western medicine and traditional Chinese medicine (TCM). Traditional western medicine has no specific remedy for diabetic cardiomyopathy, and the resulting side effect cannot be neglected. In order to improve the efficacy and reduce the side effects, researchers have tried some potential medical treatments, such as vaspin, melatonin, Coenzyme Q10, and non-coding RNA, which still need further clinical trials. Diabetic cardiomyopathy is not recorded in ancient TCM books. According to the symptoms and signs, modern physicians often consider it as a "consumptive disease", whose main therapeutic principles lie in benefiting Qi, tonifying Yin, activating blood, and removing stasis. The individual Chinese herbs such as Astragali Radix and Salviae Miltiorrhizae Radix et Rhizoma and Chinese herbal compounds like Huotan Jiedu Tongluoyin are effective in protecting the heart. But there are few studies exploring the pharmacodynamic mechanisms of TCM. With the continuous emergence of new drugs, the integration of TCM with western medicine may be a more promising treatment in the future. In conclusion, the pathogenesis of diabetic cardiomyopathy is unclear, and there is a lack of effective prevention and treatment. This paper reviewed the latest findings in pathogenesis and treatment of diabetic cardiomyopathy, in order to provide reference for further research.
