     [摘要] 目的运用组织多普勒成像(TDI)技术测定非体外循环冠状动脉旁路移植(OPCAB)术前后左心室长轴功能的变化，并探讨其临床意义。方法应用TDI技术测定48例冠心病病人在OPCAB术前、术后1周和术后3月二尖瓣环收缩期心肌峰值运动速度(SM)和位移(DS)及收缩前期时间(PCTM)，舒张早期心肌峰值运动速度(EM)，心房收缩期心肌峰值运动速度(AM)，计算EM/AM比值。结果与OPCAB术前比较，SM在术后1周和术后3月明显增加(F=9.80,q=3.53、9.27,P<0.01)；DS在术后1周和术后3月明显增加(F=7.74,q=4.45、7.81,P<0.01)；PCTM在术后1周和术后3月显著减小(F=6.21,q=3.18、6.11,P<0.01)；EM在术后1周和术后3月显著增加(F=10.72,q=9.86、11.21,P<0.01)；EM/AM比值在术后1周和术后3月显著升高(F=9.12,q=3.12、8.34,P<0.01)。结论左心室长轴功能在OPCAB术后1周明显改善，并且随时间推移进一步改善，TDI为准确评价OPCAB术前后左心室长轴功能的变化提供了一条新途径。

    ALTERATION OF LEFT VENTRICULAR LONGAXIS FUNCTION FOLLOWING OFFPUMP CORONARY ARTERY BYPASSLI RONG, SONG MINGFANG, WANG ZHIBIN, et al (Department of Cardiac Ultrasound, The Affiliated Hospital of Qingdao University Medical College，Qingdao 266003, China)

    [ABSTRACT]ObjectiveTo measure the left ventricular longaxis function, using tissue Doppler imaging (TDI), in patients before and after offpump coronary artery bypass (OPCAB) and to investigate its clinical significance. MethodsLongaxis function parameters were measured using TDI in 48 patients before and 1 week and 3 months after OPCAB in mitral annulus level, including peak systolic velocity (SM) and excursion (DS), the time interval from ECG Q wave to SM (PCTM), early diastolic peak velocity (EM), late diastolic peak velocity (AM) and EM/AM. ResultsSM was higher after OPCAB than before (F=9.80, q=3.53 ......
