摘要
目的探讨急性前壁透壁性心肌梗死时下壁导联ST段压低的临床价值。方法比较任一下壁导联ST段压低≥1.0mm的17例与压低均<1.0mm的16例的CK_MB值、超声心动描记术、冠状动脉造影等结果。结果前组CK_MB值更高 ,射血分数减低更显著 ,左室收缩与舒张末期容积更大 ,造影术示致梗死狭窄病变多位于左前降支近端或呈多支病变。结论急性前壁心肌梗死下壁导联ST段压低≥1.0mm时 ,其梗死面积较大 。
Objective This study evaluated clinical value of inferior ST segment depression in acute transmural anterior myocardial infarction.Methods Severteen cases with most pronounced ST segment depression≥1.0 mm in any inferior lead were compared with 16 cases with maximally depressed ST segment<1.0 mm in all inferior ST segments by CK _ MB value,echocardiography,coronary arteriography.Results Former showed higher CK _ MB value,lower left ventricular ejection fraction and larger left ventricular endsystolic and end diastolic volume,culprit occlusions on proximal segment of left anterior descending branch and multibranch lesions existing on coronary arteriography.Conclusion In patients with acute transmural anterior myocardial infarction inferior ST segment depression≥1.0 mm predicted larger infarct size,then more severe left ventricular dysfunction and left ventricular remodelling occur.
