【摘要】：目的應(yīng)用超聲斑點(diǎn)追蹤技術(shù)(STI)檢測(cè)冠心病(CAD)患者左室應(yīng)變及扭轉(zhuǎn)參數(shù),并與紐約心功能分級(jí)積分(NYHA-P)進(jìn)行比較分析,探討STI定量評(píng)估CAD心功能分級(jí)的價(jià)值。方法隨機(jī)對(duì)70例CAD患者按NYHA-P分為紐約心功能分級(jí)正常或接近正常組(40例)及心功能分級(jí)異常組(30例),并選擇正常對(duì)照組(30例),比較受檢者NYHA-P、左室射血分?jǐn)?shù)(LVEF)、左室心肌整體徑向應(yīng)變(GRS)、縱向應(yīng)變(GLS)、左室心肌收縮期心肌扭轉(zhuǎn)角度(TA)。結(jié)果 CAD組與對(duì)照組比較:LVEF、GLS、GRS、TA減低(P0.05);心功能正常組與異常組比較:LVEF、GLS、GRS、TA減低(P0.05);正常組GLS、GRS、TA與LVEF無(wú)相關(guān)性,與NYHA-P相關(guān);異常組GLS、GRS、TA與LVEF及NYHA-P呈相關(guān)性;以GLS-14.65%截?cái)帱c(diǎn)判定患者NYHAP積分高于4.5分的靈敏度為87.30%、特異度為75%,Yuedden指數(shù)最高為0.653。結(jié)論 2D-STI技術(shù)檢測(cè)心肌應(yīng)變及扭轉(zhuǎn)評(píng)價(jià)CAD左心室局部功能具有獨(dú)特的優(yōu)越性,局部應(yīng)變及扭轉(zhuǎn)參數(shù)與左室射血分?jǐn)?shù)不一定相關(guān),但與臨床心功能分級(jí)相關(guān),應(yīng)變及扭轉(zhuǎn)評(píng)價(jià)臨床心功能較左室射血分?jǐn)?shù)敏感,可以定量評(píng)價(jià)CAD患者實(shí)際臨床心功能狀態(tài)。
[Abstract]:Objective to detect the parameters of left ventricular strain and torsion in patients with coronary heart disease (CAD) by using ultrasonic dot tracing technique (STI), and to evaluate the value of STI in quantitative evaluation of CAD cardiac function grade.Methods 70 patients with CAD were randomly divided into New York cardiac function grade group (n = 40) and abnormal cardiac function grade group (n = 30) according to NYHA-P, and 30 normal control group (n = 30). The patients were compared with each other (NYHA-P, left ventricular ejection fraction (LVEF), left ventricular ejection fraction (LVEF), left ventricular ejection fraction (LVEF), left ventricular ejection fraction (LVEF)).Global radial strain of myocardium GRSs, longitudinal strain of GLSN, left ventricular torsion angle of myocardial torsion.緇撴灉 CAD緇勪笌瀵圭収緇勬瘮杈，
