摘要 目的:通过腺苷负荷实时心肌声学造影与冠脉造影对比分析心肌声学造影(Myocardial contrast echocardiography,MCE)在冠心病诊断中的应用价值。方法:30例拟诊断冠心病住院患者进行常规超声心动图、基础状态下和腺苷负荷状态下的心肌声学造影以及选择性冠状动脉造影。MCE造影图像采用QLab软件对微泡再充盈曲线进行定量分析,求出各节段的A值、β值及其乘积A×β值。对各节段心肌灌注参数和其供血冠状动脉的狭窄程度进行统计学分析。结果:基础状态下,β值和A×β值随着供血冠状动脉狭窄程度的增加而降低(P<0.01);在负荷状态下,A值、β值和A×β值随着供血冠状动脉狭窄程度的增加而降低(P<0.01),且其储备值呈现出相同的趋势(P<0.01)。结论:心肌声学造影与冠脉造影相结合既可准确地揭示冠状动脉的解剖畸形及其阻塞性病变的位置、程度与范围,又可准确的评价心肌的微灌注,能帮助更好地选择冠心病的治疗方法,判断预后。
