摘要:: 目的探讨前壁导联ST段压低与急性下壁心肌梗死(MI)冠脉病变程度及预后的关系。方法根据MI初期是否并发前壁导联ST段压低将96例急性下壁MI分为两组即前壁导联ST段压低组(A组，56例)和前壁导联ST段无压低组(B组，40例)，将两组冠脉造影结果、梗死部位及预后进行比较分析。结果 A组多支血管病变(52％)、梗死相关血管近端病变(82％)，下后壁MI(88％)、下后壁+右室MI(90％)，心力衰竭 (16%)、心源性休克(14%)、室速(21%)。B组多支血管病变(30％)、梗死相关血管近端病变(22％)，下后壁MI(12％)、下后壁+右室MI(10％)，心力衰竭(2%)、心源性休克(2%)、室速(8%)。两组分项比较差异均显著(均P<0.05)。结论并发胸前导联ST段压低的急性下壁MI多为多支血管病变，梗死相关血管多为近端病变，梗死部位多，预后不良。

Abstract:: AIM To explore the relationship between the severity of coronary artery disease, its prognosis and STsegment depression on anterior wall during acute inferior myocardial infarction (AIMI). METHODS Ninetysix patients with AIMI were divided into two groups: ST depression group (group A, n=56) and noST depression group (group B, n=40) based on STchanges in the anterior leads. The data of both groups were compared with the coronary angiographic findings, the section of myocardial infarction and prognosis. RESULTS The cases with multivessel lesions (52%), proximal lesions of infarction related artery (82%), inferiorposterior AMI (88%), inferiorposterior AMI accompanied by right ventricular infarction (90%), heart failure (16%), cardiogenic shock (14%), ventricular tachyrhythmia (21%) in group A were more than those in group B. CONCLUSION Multivessel disease, proximal lesion of infarction related artery, multisection of myocardial infarction, and poor prognosis are more likely to occur in a patient of AIMI with STsegment depression on anterior wall.
