Application of RT-3DE in Ventricular Remodeling in Heart Failure Patients with Reduced LVEF

doi:10.7517/issn.1674-0475.220107

Abstract

Abstract: This paper discussed the left ventricular remodeling in heart failure patients with reduced left ventricular ejection fraction (LVEF) by real-time three-dimensional echocardiography (RT-3DE). 110 patients with heart failure with reduced LVEF were selected as the observation group and 50 healthy people were selected as the control group. They all underwent RT-3DE, and observed the ventricular parameters of the two groups. The results showed the right ventricular end diastolic volume index (RVEDVI), right ventricular end systolic volume index (RVESVI) and right ventricular basal long diameter (RVLD) were significantly higher than that in the control group (P<0.05), while the LVEF was significantly lower than that in the control group (P<0.05). The RVEDVI, RVESVI and RVLD of patients with pulmonary hypertension (PH) ≥ 80 mmHg were higher than those of other patients (P<0.05) in the observation group, while LVEF was lower than that of other patients (P<0.05). There had correlations between PH and RVEDVI, RVESVI and LVEF (r=0.454, 0.420 and -0.331, P<0.05). PH in patients with heart failure with reduced LVEF has a certain effect on ventricular remodeling, which is worthy of further study.

Key words: left ventricular ejection fraction, heart failure, pulmonary hypertension, ventricular remodeling, real-time three-dimensional echocardiography
