Abstract: Objective To investigate the correlation between serum level of free triiodothyronine (FT3) and readmission due to heart failure in the elderly patients with ischemic cardiomyopathy and heart failure. Methods A total of 89 elderly patients with ischemic cardiomyopathy and heart failure admitted to Department of Vasculocardiology, Nanjing Drum Tower Hospital from March 2018 to December 2019 were enrolled. According to whether the readmission was due to heart failure, the patients were divided into heart failure readmission group (group A, n=24) and non-heart failure readmission group (group B, n=65). The baseline data, serological indexes and echocardiographic indexes of the two groups were compared during hospitalization. Multivariate Logistic regression was used to analyze the related factors of readmission due to heart failure. Results The proportion of male patients in group A was lower than that in group B, the levels of BNP and globulin were higher than those in group B, and the level of FT3 was lower than that in group B (all P<0.05). Multivariate Logistic regression analysis showed that after adjusting ejection fraction (EF), left ventricular end-diastolic diameter(LVEDD), BNP, globulin, gender, stroke and other factors, decreased FT3 was an independent risk factor for readmission due to heart failure (OR=0.198, 95%CI: 0.040-0.966). Conclusions Decreased FT3 is an independent risk factor for readmission due to heart failure in the elderly patients with ischemic cardiomyopathy and heart failure.
