Effect of Transthoracic Echocardiography on Prognosis Outcomes in Diabetic Patients With Various Cardiovascular Diseases: A Retrospective Cohort Study Based on the MIMIC-IV Database.

ObjectiveThis study aimed to investigate the association between transthoracic echocardiography (TTE) and prognosis in diabetic patients without complications who present with seven types of cardiovascular diseases.MethodsData were sourced from the Medical Information Mart for Intensive Care (MIMIC)-IV database (N = 5553). The included participants were divided into TTE examination (n = 2263) and non-TTE examination (n = 3290) groups. Clinical endpoints included survival time, initial Intensive Care Unit (ICU) admission, and hospital readmission. Logistic and Cox regression analyses were conducted to assess the relationship between TTE examination and these outcomes. Receiver operating characteristic (ROC) curves evaluated the predictive exploratory prognosis utility of TTE examination. The Kaplan-Meier (KM) and restricted mean survival time (RMST) analyses were used to compare the survival difference between the TTE examination and non-TTE examination groups.ResultsSignificant differences were observed in the distribution of the other three outcomes between the TTE examination and non-TTE examination groups (all p
