旨在
比较长轴功能和室壁运动分析检测单支和多支病变患者的显著冠状动脉狭窄。
方法和结果
我们对67例受试者进行了多巴酚丁胺负荷超声心动图检查，其中14例冠状动脉解剖正常，53例有明显的冠状动脉疾病。平均长轴缩短的钝性增加<0.25 cm是冠状动脉疾病的最佳诊断标准（敏感性85%，特异性81%）。使用该阈值，长轴功能检测静息室壁运动正常患者的冠状动脉疾病的敏感性为88%，特异性为89%，而室壁运动异常分析的敏感性为73%，特异性为94%。在26例静息室壁运动异常的患者中，14例（54%）有多支血管病变。其中12例（敏感性86%）长轴功能检测到多支血管病变，而室壁运动分析检测到9例（敏感性64%）。
结论
长轴功能为多巴酚丁胺负荷超声心动图检测单支和多支血管病变及静息室壁运动异常患者的冠状动脉缺血提供了一种有前景的定量辅助室壁运动分析。
AIMS
To compare long-axis function and wall motion analysis for the detection of significant coronary artery stenoses in patients with single and multivessel disease.
METHODS AND RESULTS
We performed dobutamine stress echocardiography in 67 subjects, 14 with normal coronary anatomy, and 53 with significant coronary disease. A blunted increase in mean long-axis shortening of <0.25 cm was the best discriminator for coronary artery disease (sensitivity 85%, specificity 81%). Using this threshold, long axis function gave a sensitivity of 88% and specificity 89% for the detection of coronary artery disease in patients with normal resting wall motion while wall motion abnormality analysis had a sensitivity 73% and specificity 94%. Of 26 patients with a resting wall motion abnormality, 14 (54%) had multivessel disease. Long axis function detected multivessel disease in 12 of these (sensitivity 86%) compared with nine (sensitivity 64%) for wall motion analysis.
CONCLUSION
Long axis function provides a promising, quantitative adjunct to wall motion analysis for the detection of coronary ischaemia using dobutamine stress echocardiography in patients with single and multivessel disease and with resting wall motion abnormalities.
