Abstract

In this chapter, we start by discussing coronary artery bypass grafting and the most common complication after surgery – post coronary artery bypass grafting atrial fibrillation (PCAF). We then discuss the major risk factors for PCAF, and subsequently conduct an in-depth discussion of obstructive sleep apnea as a risk factor. In this endeavor, we outline how obstructive sleep apnea is diagnosed, its pathophysiological relationship to PCAF, and recent clinical studies investigating the association between obstructive sleep apnea and PCAF. We conclude with prevention and treatment strategies for PCAF, and a discussion of future research recommendations.

En este capítulo comenzamos analizando la cirugía de revascularización miocárdica y su complicación más frecuente, la fibrilación atrial postoperatoria. Analizamos los principales factores de riesgo para la fibrilación atrial postoperatoria y luego discutimos detalladamente la apnea obstructiva del sueño como factor riesgo. En este empeño, describimos cómo se diagnostica la apnea obstructiva del sueño, su pato-fisiología en relación con la fibrilación atrial postoperatoria y los estudios clínicos que recientemente han investigado la asociación entre la apnea obstructiva del sueño y fibrilación atrial postoperatoria. Concluimos con las estrategias de prevención y tratamiento de la fibrilación atrial postoperatoria y la discusión de futuras recomendaciones investigativas.
