Abstract
AimsThe triglyceride glucose (TyG) index is a marker of insulin resistance. However, the prognostic value thereof in patients with chronic heart failure (CHF) and type 2 diabetes remains unclear. MethodsThis study included patients diagnosed with CHF and type 2 diabetes in Fuwai Hospital of Chinese Academy of Medical Sciences, Shenzhen, from January 2017 to July 2019. The primary endpoint was cardiovascular death or rehospitalization for heart failure. ResultsThe study included 546 patients with CHF and type 2 diabetes. We divided the patients into three groups (T1 [TyG index < 8.55], T2 [TyG index ≥ 8.55 and < 9.06], and T3 [TyG index ≥ 9.06]) according to the TyG index level. The incidence of the primary outcome in the T3 group was significantly higher than that in the T1 group. There was no significant difference between the T1 and T2 groups. The trend test revealed a positive correlation between the TyG index and the incidence of the primary outcome (P = 0.001). ConclusionsThere is a positive correlation between the TyG index and the prognosis of patients with CHF and type 2 diabetes.
