实时三维超声评价骨关节退变患者左心室重构指数

摘要

目的 近年来骨关节退变发病率增加,合并心血管疾病日益增多.本研究采用实时三维超声心动图(RT-3DE)准确评估左心室重构指数(LVRI),以期指导临床治疗,提高患者生存率.资料与方法 回顾性分析2015年7月-2016年4月于青岛大学附属医院57例健康志愿者(正常对照组)以及67例骨关节退变患者(研究组),根据年龄各分成两个亚组.两组均行常规超声及RT-3DE检查,比较不同方法所测得的LVRI、左心室舒张末期容积指数(LVEDVI)、左心室质量指数(LVMI)、左心室收缩末期容积指数(LVESVI)、左心室射血分数(LVEF)在各组间及各组内的差异及相关性.结果 研究组与正常对照组年龄差异无统计学意义(P＞0.05);研究组LVRI、LVMI明显高于同年龄段正常对照组(P＜0.05);M型超声和二维超声所测LVEDVI、LVMI、LVRI均高于RT-3DE,差异有统计学意义(P＜0.05);经Bland-Altman一致性检验,RT-3DE和二维超声测量LVRI具有较好的一致性.结论 骨关节退变患者出现左心室重构,RT-3DE能够较为准确地测量LVRI,且操作方便、无放射性损伤,可广泛应用于临床.%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.
