分析55例心肌梗塞(MI)心电图(ECG)和冠状动脉造影(CAG)定位MI的符合程度,结果表明,左回旋支为梗塞相关动脉的病例符合率明显低于右冠状动脉或左前降支为梗塞相关动脉的病例(P<0.05);下壁MI病例较前壁MI病例符合率低(P<0.05);有侧支循环病例较无侧支循环病例符合率低(P<0.05);不典型MI的ECG表现为MI定位不符合的主要原因,而多支病变,陈旧MI易产生不典型MI的ECG,8例中全是多支病变,6例为陈旧MI;尿激酶静脉溶栓后梗塞相关动脉再通和未通病例MI定位符合率无差别(P>0.05)。
The coincidence of myocardial infarction (MI) electrocardiogram (ECG) and coronary artery angiography (CAG) localization MI was analyzed. The results showed that the compliance rate of left circumflex artery in infarcted artery was significantly lower than that of right coronary artery or left anterior descending artery (P <0.05). The coincidence rate of inferior wall MI was lower than that of anterior wall MI (P <0.05). The coincidence rate of patients with collateral circulation was lower than that without collateral circulation (P <0.05). Typical MI of the ECG showed the main reason for the mismatch of MI, while multivessel disease, old MI easy to produce atypical MI ECG, 8 cases were all multi-vessel disease, 6 cases of old MI; urokinase after intravenous thrombolysis There was no difference in the coincidence rate of infarction-related arterial recanalization and unobserved MI (P> 0.05).
