摘要
目的应用二维斑点追踪显像(2DSTI)技术评价生理性和病理性左心室心肌肥厚的左心室功能。方法高心组(50例),运动员组(25例)和对照组(25例)。应用STI技术测定左心室各壁基底段、中间段和心尖段收缩期峰值应变(Ss)和收缩期峰值应变率(SRs),并对结果进行分析。结果与对照组和运动员组比较,高心组Ss和SRs均显著降低(均P<0.05),对照组和运动员组比较无显著性差异(P>0.05)。结论 STI技术可实时、准确地反映心肌收缩功能状况,并可对生理性肥厚心肌和高血压左心室肥厚进行鉴别。
Objective To evaluate the left ventricular function of pathologic and physiologic left ventricular hypertrophy us- ing two-dimensional speckle tracking imaging. Methods 50 cases of hypertension heart group, 25 cases of athlete group and 25 cases of the control group were selected, systolic peak strain （Ss）, systolic peak strain rate （SRs） were measured at basal, middle and apical segments, and the results were analyzed. Results The Ss and SRs in hypertension heart group were all significantly lower than those of control group and athlete group （all P 〈 0.05）. The difference of Ss and SRs be- tween athlete group and control group was not statistically significant （P 〉 0.05）. Conclusion STI can not only distinguish left ventricular hypertrophy in hypertension patients and physiologic hypertrophy in athletes but also assess the function of the left ventricle accurately.
