Abstract

Introduction: Atrial fibrillation (AF) recurrence after a successful external electrical cardioversion (ECV) is common. Assessing an individual's risk of AF recurrence is a critical part of the treatment plan. We aimed to develop a prognostic prediction score to predict AF recurrence in AF patients who underwent successful ECV.

Methods: A retrospective cohort study that included AF patients who underwent successful ECV was conducted with a primary outcome of AF recurrence at 6 months. Logistic regression analysis was done to identify variables, and a prognostic prediction score was created and internally validated.

Results: Four prognostic predictors were identified, including the type of AF, persistent AF (1 point) and long-standing persistent AF (4 points), previous cardioversion (1 point), stroke/transient ischemic attack (3 points), and left atrial volume index ≥40 mL/m 2 (6 points). The total score of 14 was further divided into 3 risk groups; low-risk (0-2 points), moderate-risk (3-7 points), and high-risk (8-14 points). The positive likelihood ratio for a moderate-risk patient was 2.08 (95% CI, 1.64-2.63) and for a high-risk patient was 7.90 (95% CI, 2.48-25.17). The score showed good discrimination power with the c-statistic of 0.74 (95% CI, 0.69-0.79).

Conclusions: A simple prognostic prediction score for AF recurrence after successful ECV was created with a promising internally validated discrimination power. An external assessment of its usefulness as a tool to identify patients with low, moderate, and high risk for AF recurrence is warranted.

预测体外电复律后房颤复发的预后评分- slac评分。

心房颤动(AF)在体外电复律(ECV)成功后复发是常见的。评估个体的房颤复发风险是治疗计划的关键部分。我们的目的是建立一个预后预测评分来预测成功接受ECV的房颤患者的房颤复发。方法:一项回顾性队列研究，包括成功接受ECV治疗的房颤患者，主要结局为房颤6个月复发。进行逻辑回归分析以确定变量，并创建预后预测评分并进行内部验证。结果:确定了房颤类型、持续性房颤(1分)和长期持续性房颤(4分)、既往心律转复(1分)、卒中/短暂性脑缺血发作(3分)、左房容积指数≥40 mL/ m2(6分)等4个预后预测因素。总分14分进一步分为3个风险组;低风险(0-2分)、中度风险(3-7分)、高风险(8-14分)。中危患者的阳性似然比为2.08 (95% CI, 1.64-2.63)，高危患者的阳性似然比为7.90 (95% CI, 2.48-25.17)。c统计量为0.74 (95% CI, 0.69 ~ 0.79)，具有良好的判别能力。结论:建立了一个简单的预测ECV成功后房颤复发的预后评分，具有良好的内部验证的鉴别能力。有必要对其作为识别AF复发低、中、高风险患者的工具的有效性进行外部评估。
