摘要
目的 探讨全心尖切面心肌背向散射积分参数评价心肌缺血的可靠性。方法 分析 22例冠心病 (CAD)患者和 18例冠状动脉定量造影(QCA)正常患者的全心尖切面心肌所测左室 16个节段背向散射积分参数,分别比较CAD组中室壁运动异常节段心肌、室壁运动正常节段心肌及对照组心肌的CVIB、CVIB%及AII%值。结果 CAD组中室壁运动异常节段心肌CVIB、CVIB%值均显著低于后二者,而AII%值则显著高于后二者。结论 全心尖切面所测左室 16个节段背向散射积分参数能够敏感、客观并比较全面地反映心肌缺血情况。
Objective To investigate the reliability of integrated backscatter in assessment of myocardial ischemia with total apical views. Methods Twenty two patients with coronary artery disease (group CAD) and 18 patients whose quantitative coronary angiography (group CON) were normal received integrated backscatter analyzing. CVIB, CVIB% and AII% of the segments of abnormal wall motion in group CAD were compared with those of the segments of normal wall motion in group CAD and group CON. Results CVIB, CVIB% in the segments of abnormal wall motion were significantly lower than those in the segments of normal wall motion in group CAD and the segments of group CON, but the value of AII% were significantly higher in the segments of abnormal wall motion in group CAD. Conclusion IBS analysis of myocardium in total apical views can give a sensitive, objective and overall detection of myocardial ischemia.
