目的 探讨超声造影在检测心肌梗死患者左室壁受损范围中的价值.方法 对75名发生心肌梗死的患者进行实时心肌造影,分别于超声造影前后观察心内膜边界显示情况,评价和比较节段室壁运动情况.结果 超声造影后左室心内膜边界的显示较造影前明显清晰,受损节段与未受损节段的对比增强.以冠状动脉造影结果为标准,造影检测的灵敏度、特异度和准确度均高于造影前(p<0.05).结论 实时超声造影能有效增强左室心内膜边界显示和受损心肌边界显影,提高对左室壁受损范围检测的准确性.
目的 探討超聲造影在檢測心肌梗死患者左室壁受損範圍中的價值.方法 對75名髮生心肌梗死的患者進行實時心肌造影,分彆于超聲造影前後觀察心內膜邊界顯示情況,評價和比較節段室壁運動情況.結果 超聲造影後左室心內膜邊界的顯示較造影前明顯清晰,受損節段與未受損節段的對比增彊.以冠狀動脈造影結果為標準,造影檢測的靈敏度、特異度和準確度均高于造影前(p<0.05).結論 實時超聲造影能有效增彊左室心內膜邊界顯示和受損心肌邊界顯影,提高對左室壁受損範圍檢測的準確性.

Objective To investigate the value of real-time contrast echocardiography in detecting the abnormal wall of left ventricular in patients with myocardial infarction. Methods There were 75 patients with myocardial infarction enrolled in this study. Before and after real-time contrast echocardiography, the left ventricular endocardial border was observed and the regional wall motion was assessed and compared. Results After contrast enhancement, the endocardial border was delineated more precisely. The difference of echogenicity between the normal wall and adnormal wall was enlarged. The sensitivity, specificity and accuracy of echocardiography in detecting regional wall motion abnormalities were higher with contrast agents than those pre-contrast. Conclusion Real-time contrast echocardiography can delineate left ventricular endocardial border and enhance the border of adnormal wall more precisely, which improves the accuracy of detecting the abnormal wall of left veutricular.
