【摘要】：目的應用xPlane技術測量肺動脈高壓(PH)患者右室縱向縮短分數(shù)(LSF),并與心臟磁共振(CMR)測量右室射血分數(shù)(CMR-RVEF)比較,探討該參數(shù)評價PH右心功能改變的臨床應用價值。方法臨床確診PH患者106例。超聲心動圖右心功能參數(shù)包括:右心室縱向縮短分數(shù)(LSF)、三尖瓣環(huán)收縮期位移(TAPSE)、右室面積變化分數(shù)(RVFAC)及右心做功指數(shù)(RIMP)。41例患者應用CMR測量右室射血分數(shù)(RVEF-CMR)。結果 (1)LSF與TAPSE呈正相關關系,與RIMP呈負相關關系,與RVFAC呈正相關關系(P0.001)。(2)LSF_(APm)預測RVEF-CMR45%曲線下面積為0.780;以15.5%作為界值判定靈敏度62.07%、特異度91.67%。(3)將PH患者以LSF_(APm)截斷值15.5%分為2組,組Ⅰ患者LSF_(APm)≥15.5%,組Ⅱ患者LSF_(APm)15.5%。組Ⅱ患者較組Ⅰ患者TAPSE及RVFAC顯著降低,RIMP明顯升高(P0.001)。結論 LSF能夠反映PH患者右心功能減低程度,為臨床評估患者右心功能情況,制定治療方案提供一種新的診斷指標。
[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，
