方法和结果:我们检索了 2000 年至 2008 年的 MEDLINE 和 Cochrane 中心试验注册数据库,寻找报告术前预测因素和射频消融后 AF 复发的研究。我们提取了关于预测因子和 AF 复发的多变量分析和单变量数据。符合条件的研究具有高度异质性,特别是在消融技术和房颤复发定义方面。在 25 项多变量分析研究中,三分之二至 90% 的研究发现 AF 类型、射血分数、左心房直径、结构性心脏病、高血压和 AF 症状持续时间不能预测 AF 复发(射血分数高于 40% 且左心房直径低于约 55 mm 的患者)。研究发现,性别和年龄并不是预测因素(40 至 70 岁的患者)。对 31 项研究中按 AF 类型划分的单变量 AF 复发率进行荟萃分析发现,研究存在统计学异质性,但与阵发性 AF 相比,非阵发性 AF 可以预测 AF 复发(相对风险 1.59;95% 置信区间 1.38-1.82;P < 0.001);持续性或永久性与阵发性 AF 的荟萃分析得出了类似的结果。结论:非阵发性 AF 可能是临床上有用的混杂变量组合的代表,其中没有一个单独是 AF 复发的独立预测因子。由于排除了患有严重心脏病或处于极端年龄的患者,预测因素的评估受到限制;因此,证据可能不适用于这些人群。 (《心血管电生理杂志》,第 21 卷,第 1208-1216 页,2010 年 11 月)。
Methods and Results: We searched MEDLINE and Cochrane Central Trials Registry databases from 2000 through 2008 for studies reporting preprocedure predictors and AF recurrence after radiofrequency ablation. We extracted multivariable analyses and univariable data on predictors and AF recurrence. Eligible studies were highly heterogeneous, particularly regarding ablation technique and definition of AF recurrence. Among 25 studies with multivariable analyses, two-thirds to 90% of studies found that AF type, ejection fraction, left atrial diameter, structural heart disease, hypertension, and AF symptom duration did not predict AF recurrence (among patients with ejection fraction above 40% and left atrial diameter below about 55 mm). Studies found that gender and age were not predictors (in patients between 40 and 70 years old). Meta-analyses of univariable AF recurrence rates by AF type in 31 studies found that studies were statistically heterogeneous, but that nonparoxysmal AF predicted AF recurrence compared to paroxysmal AF (relative risk 1.59; 95% confidence interval 1.38-1.82; P < 0.001); meta-analyses of persistent or permanent versus paroxysmal AF yielded similar findings.Conclusion: Nonparoxysmal AF may be a clinically useful proxy for a combination of confounded variables, none of which alone is an independent predictor of AF recurrence. Evaluation of predictors was limited by exclusion of patients with severe heart disease or at the age extremes; thus, the evidence may not be as applicable to these populations.
