With the improvement of living standards,the incidence and mortality of cardiovascular diseases are increasing year by year and have become an important public health problem.Insulin resistance status is closely related to the pathophysiologic process in the occurrence and development of cardiovascular diseases.In-depth study of the intrinsic link between insulin resistance and cardiovascular diseases is essential for early prevention,treatment,and follow-up of cardiovascular diseases.Traditional insulin resistance testing methods are cumbersome,time-consuming,and expensive,making them unsuitable for hospitals,not to mention being unable to be generalized in large-scale populations.Metabolic Score for Insulin Resistance(METS-IR)is a new type of predictors of insulin resistance,and METS-IR reflects insulin resistance with high efficiency and simplicity.Moreover,elevated METS-IR is positively correlated with cardiovascular diseases and poor cardiovascular prognosis.Based on this,this article summarizes the diagnostic and clinical value of METS-IR in common cardiovascular diseases.
