| 摘 要： | 目的 分析左房容积指数(left atrial volume index,LAVI)与非体外循环冠状动脉搭桥(off-pump coronary artery bypass grafting,OPCABG)术后房颤的相关性,评价其对非体外循环冠状动脉搭桥术后房颤(atrial fibrillation,AF)的预测价值。 方法 选择北京市大兴区人民医院2016年1月-2017年12月期间97例行非体外循环冠状动脉搭桥术患者,术前常规检查超声心动图,应用三维超声测量左房容积(left atrial volum,LAV),并测量身高、体重,计算标准化体表面积(standardized surface area,BSA)。按术后是否发生房颤分为房颤组和非房颤组。对2组患者左房容积指数、年龄、病史、术前用药、超声心动图等相关因素进行分析。同时按LAVI ≥ 32 ml/m2进行分组,比较2组患者术后房颤发生情况。 结果 房颤组与非房颤组在左房容积指数、年龄、左室射血分数(left ventricular ejection fraction,LVEF)差异有统计学意义(P<0.05);多因素分析结果显示左心房容积指数、年龄为OPCABG术后房颤发生的独立预测因子。LAVI ≥ 32 ml/m2的患者,OPCABG术后房颤发生率明显增加,差异有统计学意义(P<0.05)。 结论 LAVI是OPCABG术后房颤的预测因子,可为有效预防和及时治疗术后房颤,缩短住院时间、改善预后提供依据。

| Abstract: | Objective To investigate the relationships between left atrial volume index (LAVI) and atrial fibrillation (AF) after off-pump coronary artery bypass (OPCABG) and evaluate the predictive value of LAVI. Methods The clinical data of 97 cases of OPCABG from January, 2016 to December, 2017 were collected, they were examined preoperatively on transthoracic echocardiography, The left atrial volume was measured by three-dimensional ultrasound, and the height and weight were measured, and the Standardized Surface Area was calculated. All patients were divided into atrial fibrillation group and non-atrial fibrillation group. By compared the clinical relative factors of the two groups patients, analyzed the factors of LAVI, age, medical history, Premedicate, with AF after OPCABG According to LAVI ≥ 32 ml/m2, the occurrence of atrial fibrillation between the two groups was compared. Results Univariate analysis showed that the age, left atrial volume index, in the AF group were significantly higher than that of the non-AF group, left ventricular ejection fraction in the AF group were significantly lower than that of the non-AF group (P<0.05). Multifactor analysis showed that the left atrial volume index was an independent predictor of atrial fibrillation after OPCABG. In patients with LAVI ≥ 32 ml/m2, the incidence of atrial fibrillation increased significantly after OPCABG. Conclusion LAVI was an independent predictor of atrial fibrillation after OPCABG, effective prevention and timely treatment of postoperative atrial fibrillation, shortened hospital stay and improved prognosis. |
