【摘要】：目的探讨右冠状动脉和左回旋支病变引起急性下壁心肌梗死患者临床特点的差异。方法选择急性下壁心肌梗死295例患者,根据冠脉造影检查情况分为右冠状动脉病变232例(右冠脉组)和左回旋支病变63例(左回旋支组)。统计分析两组入院时心功能分级、心电图表现、左室舒张末期内径、左室射血分数及入院30 d患者死亡情况。结果与右冠脉组比较,左回旋支组入院时心功能Killip分级较差(P0.05)。右冠脉组心电图ST段抬高Ⅲ导联Ⅱ导联、V_(4R)ST段抬高及ST段抬高Ⅲ导联Ⅱ导联合并房室传导阻滞发生率高于左回旋支组(P均0.05)。左回旋支组V_7~V_9、V_5~V_6导联及Ⅰ、a VL导联ST段抬高发生率高于右冠脉组,左回旋支组左室射血分数低于右冠脉组,入院30 d病死率高于右冠组,两组差异均有统计学意义(P均0.05)。结论右冠状动脉和左回旋支引起的急性下壁心肌梗死心电图表现不同,左回旋支引起的急性下壁心肌梗死患者心功能Killip分级差,病死率较高。
[Abstract]:Objective to investigate the clinical characteristics of patients with acute inferior myocardial infarction caused by right coronary artery disease and left circumflex artery disease. Methods 295 patients with acute inferior myocardial infarction were divided into right coronary artery disease (right coronary artery group) and left circumflex branch disease (left circumflex branch group). 232 patients were divided into right coronary artery disease (right coronary artery group) and 63 patients with left circumflex branch disease (left circumflex branch group). The cardiac function grade, electrocardiogram (ECG), left ventricular end-diastolic diameter, left ventricular ejection fraction (LVEF) and death rate at 30 days after admission in the two groups were statistically analyzed. Results compared with the right coronary artery group, the left circumflex branch group had poor Killip grade at admission. The incidence of St segment elevation, St segment elevation, lead 鈪，
