1、中文摘要目的探讨静息心电图(ECC);经静脉心肌声学造影(MCE)对冠心病的诊断价值及相关病变血管部位(前降支、回旋支、右冠状动脉)的敏感性、特异性、准确性。方法2007年5月至2008年11月内蒙古医学院第三附属医院心血管内科收治的78例患者,男女各39例,年龄45—75岁,平均年龄50.8±12.9岁,(排除心肌病、高血压心脏病、糖尿病、严重瓣膜病变、心律失常、急性左心衰及严重的肺动脉高压)o其中临床诊断冠心病急性心肌梗死(恢复期)22例,冠心病心绞痛13例(其中包括变异性心绞痛l例),可疑冠心病23例,胸痛待查20例,同期(<2周)内行静息心电图
2、、心肌声学造影及冠状动脉造影检查。结果1.MCE诊断冠心病的敏感性与静息ECG、静息ECG+btCE相比差异有统计学意义(P<0.05),且MCE随着病变支数的增加检查阳性率亦增加。静息ECC+MCE诊断冠心病的特异性与静息ECG、MCE相比差异有统计学意义(P<0.05)。2.MCE与静息ECG、静息ECG+MCE在判定LAD、LCX病变的敏感性上相比差异有统计学意义(P3、变的敏感性、特异性、准确性上相互比较差异无统计学意义(P>0.05)o结论1.静息ECG在诊断冠心病及其相关病变血管的判定方面有一定的局限性o2.MCE对冠心病及其冠状动脉LAD、LCX病变的判定有较高的敏感性,说明MCE在对冠心病及其冠状动脉LAD、LCX病变的判定方面有较高的诊断价值,其方法简便、准确且安全,可作为冠心病诊断的初筛检查。但特异性不高,尚需与CAG反复对照,进一步提高诊断的准确性。3.静息ECG+MCE对冠心病及其冠状动脉LAD、LCX病变的判定有较高的特异性,说明静息ECG+MCE在排除冠心病及LAD、LCX病变,减少假阳性方面有较4、高的参考价值。4,CAG对冠心病有极高的诊断价值,目前仍是不可取代的冠心病的诊断方法,但只提供了冠状动脉形态学方面的信息,仍有不足之处。关键词静息心电图经静脉心肌声学造影冠状动脉造影冠心病Thecomparativeanalysisofrestingelectrocardiogram,intravenousmyocardialcontrastechoardiograpyandcoronaryangiographyindiagnosisofcoronaryheartdiseaseAbstractObjectiveTodiscussonrestingele5、ctrocardiogram(ECG);intravenousmyocardialcon-trasteehoeardiography(MCE)forthediagnosisofcoronaryheartdiseaseandvascularlesionsassociatedsites(1eftanteriordescendingartery,leftcircumflexcoronaryartery,fightcoronaryartery)ofthesensitivity,specificityandaccuracy.MethodsMay2007toNov6、ember2008,78P_,asesofpatientsCanbetreatedincardiovascularmedicalwardsofthethirdaffiliatedhospi-t8lofInnerMongoliaMedicalCollege,39cagesofmenandwomen,aged45-75yearsold,theaverageageof50.8±12.9years(Excludecardiomyopathy,hypertensiveheartdisease,diabetes,severevalvedisease,cardiac7、anhythmia,acuteleftventricuI肛failureandseverepulmonaryhypertension).Clinicaldiagnosisofcoronaryheartdiseaseinwhichacutemyocar-dialinfarction(recovery)22cases,13Casesofanginapectoris(includingvariabilityinonecase8ofanginapectoris),23easesofsuspectedcoronaryheartdisease,20casesofc8、hestpainofunknownorigin,duringthe$ameperiod(<2w
