Evaluation of Left Ventricular Remodeling Index in Patients with Bone and Joint Degeneration Using Real-time Three-dimensional Echocardiography / 中国医学影像学杂志

ABSTRACT

Purpose Recently the incidence of bone and joint degeneration is increased,with the increasing of cardiovascular disease complication.This study aims to utilize realtime three-dimensional echocardiography (RT-3DE) in evaluating left ventricular remodeling index (LVRI),to guide treatment and improve the survival rate.Materials and Methods Fifty-seven cases of healthy volunteers (normal control group) and sixty-seven patients with bone and joint degeneration (research group) were respectively divided into two subgroups according to the age.Both groups underwent conventional echocardiography and RT-3DE.The LVRI,left ventricular end diastolic volume index (LVEDVI),left ventricular mass index (LVMI),left ventricular end systolic volume index (LVESVI) and left ventricular ejection fraction (LVEF) measured by different methods were analyzed,and the differences and correlations between groups and within each group were compared.Results The age of normal control group and research group was not significantly different (P＞0.05).The LVMI and LVRI in research group were significantly higher than those in the normal control group with same age (P＜0.05).The LVEDVI,LVMI and LVRI measured by two-dimensional echocardiography and M-mode echocardiography were higher than those measured by RT-3DE,and the difference was statistically significant (P＜0.05).Bland-Altman agreement analysis showed good agreement of measured LVRI using 2D echocardiography and RT-3DE.Conclusion Patients with bone and joint degeneration have left ventricular remodeling.RT-3DE can accurately assess LVRI with the advantages of convenience and lack of radiation,which can be widely used in clinic.
