Predictive factors of atrial fibrillation after coronary artery bypass grafting.

Einstein 2016 October
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.
