【摘要】：目的应用xPlane技术测量肺动脉高压(PH)患者右室纵向缩短分数(LSF),并与心脏磁共振(CMR)测量右室射血分数(CMR-RVEF)比较,探讨该参数评价PH右心功能改变的临床应用价值。方法临床确诊PH患者106例。超声心动图右心功能参数包括:右心室纵向缩短分数(LSF)、三尖瓣环收缩期位移(TAPSE)、右室面积变化分数(RVFAC)及右心做功指数(RIMP)。41例患者应用CMR测量右室射血分数(RVEF-CMR)。结果 (1)LSF与TAPSE呈正相关关系,与RIMP呈负相关关系,与RVFAC呈正相关关系(P0.001)。(2)LSF_(APm)预测RVEF-CMR45%曲线下面积为0.780;以15.5%作为界值判定灵敏度62.07%、特异度91.67%。(3)将PH患者以LSF_(APm)截断值15.5%分为2组,组Ⅰ患者LSF_(APm)≥15.5%,组Ⅱ患者LSF_(APm)15.5%。组Ⅱ患者较组Ⅰ患者TAPSE及RVFAC显著降低,RIMP明显升高(P0.001)。结论 LSF能够反映PH患者右心功能减低程度,为临床评估患者右心功能情况,制定治疗方案提供一种新的诊断指标。
[Abstract]:Objective to measure the right ventricular longitudinal shortening fraction (LSF) in patients with pulmonary hypertension (PH) by using xPlane technique, and to evaluate the clinical value of this parameter in evaluating the changes of PH right ventricular function compared with the right ventricular ejection fraction (CMR-RVEF) measured by cardiac magnetic resonance imaging (Mr).Methods 106 cases of PH were diagnosed clinically.Echocardiographic parameters of right ventricular function included right ventricular longitudinal shortening fraction (LSF), tricuspid annular systolic displacement (TAP), right ventricular area change fraction (RVFAC) and right ventricular work index (RIMP). 41 patients were measured with CMR for right ventricular ejection fraction (RVEF-CMRV).Group 鈪，
