Research progress of triglyceride glucose index in coronary atherosclerotic heart disease

Coronary heart disease (CHD) is still one of the main diseases threatening human health. With the development of economy, and the improvement of our living standards, the incidence of insulin resistance is increasing. Insulin resistance is closely related to the occurrence and development of CHD. The study of the internal relationship between insulin resistance and the pathophysiological process of CHD is of great importance for the early prevention, treatment and follow-up of CHD. The traditional testing method for insulin resistance is complicated, time-consuming and expensive, so it is not suitable to be carried out in community hospitals, cannot be promoted in large-scale populations. In recent years, triglyceride-glucose index (TyG index) as a simple insulin resistance replacement index has been paid more and more attentions. At present, many studies have confirmed that TyG index response insulin resistance is reliable, efficient and simple compared with traditional indicators of insulin resistance. Many studies have found that elevated TyG index is positively correlated with the severity of CHD and poor cardiovascular prognosis. This paper summarizes the relationship between insulin resistance and CHD, the research progress of insulin resistance detection index, and the relationship between TyG index and CHD. This article aims to improve the understanding of TyG index by general practitioners and provide more theoretical basis for them to use this insulin resistance indicator. We hope that we can use the simple marker of TyG index in the screening coronary heart disease risk groups and follow-up work for CHD, and reduce the incidence rate and mortality of CHD.
