    Abstract:
    OBJECTIVE: To evaluate the left ventricular function in patients with heart failure (HF) after myocardial infarction (MI) by real-time three-dimensional transesophageal echocardiography (RT-3D-TEE) and explore its correlation with serum cTnI and H-FABP levels. METHODS: The data of 60 HF patients after MI from March 2019 to January 2021 were analyzed retrospectively and included in the research group. According to cardiac function grades, they were assigned to group A (20 cases), group B (20 cases), and group C (20 cases). During the same period, 50 healthy patients were included in the control group. The left atrial diameter (LAD), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV), left ventricular stroke volume (LVSV), and left ventricular ejection fraction (LVEF) of participants were recorded and compared in the four groups. The serum levels H-FABP and cTnI were tested by ELISA. RESULTS: HF patients had poorer left heart structure and lower function and higher serum H-FABP and cTnI levels, as compared to the subjects in control group. Correlation analysis indicated that the cardiac function grade was positively correlated with LVEDV, LVESV, H-FABP, and cTnI, but negatively correlated with LVEF. The serum H-FABP and cTnI levels of HF patients were positively correlated with LVEDV and LVESV, but negatively correlated with LVEF. Logistic regression analysis revealed that cTnI and H-FABP were risk factors for HF, and LVEF was a protective factor for HF. CONCLUSION: Serum H-FABP and cTnI levels in HF patients are correlated with left ventricular function parameters, which presents a close relation to HF. RT-3D-TEE combined with the detection of serum H-FABP and cTnI yields important clinical significance for early diagnosis of HF.
