【摘要】：目的探討右冠狀動(dòng)脈和左回旋支病變引起急性下壁心肌梗死患者臨床特點(diǎn)的差異。方法選擇急性下壁心肌梗死295例患者,根據(jù)冠脈造影檢查情況分為右冠狀動(dòng)脈病變232例(右冠脈組)和左回旋支病變63例(左回旋支組)。統(tǒng)計(jì)分析兩組入院時(shí)心功能分級(jí)、心電圖表現(xiàn)、左室舒張末期內(nèi)徑、左室射血分?jǐn)?shù)及入院30 d患者死亡情況。結(jié)果與右冠脈組比較,左回旋支組入院時(shí)心功能Killip分級(jí)較差(P0.05)。右冠脈組心電圖ST段抬高Ⅲ導(dǎo)聯(lián)Ⅱ?qū)?lián)、V_(4R)ST段抬高及ST段抬高Ⅲ導(dǎo)聯(lián)Ⅱ?qū)?lián)合并房室傳導(dǎo)阻滯發(fā)生率高于左回旋支組(P均0.05)。左回旋支組V_7~V_9、V_5~V_6導(dǎo)聯(lián)及Ⅰ、a VL導(dǎo)聯(lián)ST段抬高發(fā)生率高于右冠脈組,左回旋支組左室射血分?jǐn)?shù)低于右冠脈組,入院30 d病死率高于右冠組,兩組差異均有統(tǒng)計(jì)學(xué)意義(P均0.05)。結(jié)論右冠狀動(dòng)脈和左回旋支引起的急性下壁心肌梗死心電圖表現(xiàn)不同,左回旋支引起的急性下壁心肌梗死患者心功能Killip分級(jí)差,病死率較高。
[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，
