Abstract

OBJECTIVE

To analyze predictive demographic and perioperative variables of postoperative atrial fibrillation in patients who underwent exclusively coronary artery bypass grafting.

METHODS

This was a retrospective cohort. We randomly selected 105 medical records of patients who underwent exclusively coronary artery bypass grafting in 2014. Demographic, clinical (preoperative and immediate postoperative) data and related with surgical procedure were collected from medical records. The occurrence of postoperative atrial fibrillation was considered until the third day after the surgery. Variables were analyzed using descriptive and inferential statistics. To identify predictive factors of postoperative atrial fibrillation we used a decision tree model with Classification and Regression Trees algorithm.

RESULTS

Atrial fibrillation incidence was 19.0% (n=20). Patients with left atrial >40.5mm and aged >64.5 years were more likely to develop the arrhythmia during the post-surgical period.

CONCLUSION

Left atrial diameter and advanced age were predictive factors of atrial fibrillation in patients who underwent exclusively coronary artery bypass grafting.

OBJETIVO

Analisar as variáveis demográficas e perioperatórias preditivas de fibrilação atrial pós-operatória em pacientes brasileiros submetidos exclusivamente à cirurgia de revascularização do miocárdio.

MÉTODOS: Trata-se de coorte retrospectiva. A amostra foi constituída de 105 prontuários de pacientes submetidos exclusivamente à revascularização do miocárdio no ano de 2014, selecionados aleatoriamente. Dados demográficos, clínicos (préoperatórios e do pós-operatório imediato) e relacionados ao procedimento cirúrgico foram coletados por meio de consulta ao prontuário. A ocorrência de fibrilação atrial no pós-operatório foi considerada até o terceiro dia após a cirurgia. As variáveis foram analisadas por estatística descritiva e inferencial. Para identificar os fatores preditivos de fibrilação atrial no pós-operatório, utilizou-se um modelo de árvore de decisão com algoritmo Classification and Regression Trees.

RESULTADOS

A incidência de fibrilação atrial pós-operatória foi de 19,0% (n=20). Pacientes com átrio esquerdo >40,5mm e idade >64,5 anos foram aqueles com mais chance de desenvolver a arritmia no pós-operatório.

CONCLUSÃO: Tamanho do átrio esquerdo e idade avançada foram fatores preditivos de fibrilação atrial em pacientes submetidos exclusivamente à cirurgia de revascularização do miocárdio.

摘要

目的

分析仅接受冠状动脉搭桥手术患者术后房颤的预测性人口统计学和围手术期变量。

方法

这是一项回顾性队列研究。我们随机选取了2014年仅接受冠状动脉搭桥手术患者的105份病历。从病历中收集人口统计学、临床(术前和术后即刻)数据以及与手术过程相关的数据。术后房颤的发生情况记录至术后第三天。使用描述性和推断性统计分析变量。为了确定术后房颤的预测因素,我们使用了带有分类与回归树算法的决策树模型。

结果

房颤发生率为19.0%(n = 20)。左心房>40.5mm且年龄>64.5岁的患者在术后更易发生心律失常。

结论

左心房直径和高龄是仅接受冠状动脉搭桥手术患者房颤的预测因素。

目的

分析仅接受心肌血运重建手术的巴西患者术后房颤的预测性人口统计学和围手术期变量。

方法

这是一项回顾性队列研究。样本由2014年随机选取的仅接受心肌血运重建手术患者的105份病历组成。通过查阅病历收集人口统计学、临床(术前和术后即刻)数据以及与手术过程相关的数据。术后房颤的发生情况记录至术后第三天。使用描述性和推断性统计分析变量。为了确定术后房颤的预测因素,使用了带有分类与回归树算法的决策树模型。

结果

术后房颤发生率为19.0%(n = 20)。左心房>40.5mm且年龄>64.5岁的患者术后发生心律失常的可能性更大。

结论

左心房大小和高龄是仅接受心肌血运重建手术患者房颤的预测因素。
