RODULFO GARCIA, Maikel; DE DIOS LORENTE, José Arturo; TORRALBAS REVERON, Fredy Eladio  and  CASTELLANOS TARDO, Juan Ramón. Atrial fibrillation in the early postoperative period of the coronary bypass surgery. MEDISAN [online]. 2013, vol.17, n.6, pp.928-933. ISSN 1029-3019.

A descriptive and cross-sectional study was carried out in 73 patients with new-onset atrial fibrillation in the first 72 hours of the postoperative period of coronary bypass surgery, surgically treated at the Cardiovascular Surgery Department of "Saturnino Lora Torres" Provincial Teaching Clinical Surgical Hospital in Santiago de Cuba, from January 2010 to the same month of 2013. In the series those older than 60 years were the most affected (71.2%), with an increase in frequency as age advanced. Males (74.3%) and smoking habit (86.0%) prevailed. Among the most remarkable factors were history of hypertension, left ventricular ejection fraction below 55.0%, incomplete revascularization and use of the bypass support. Although this arrhythmia was related to other postoperative complications, low cardiac output and strokes prevailed in this study.

Keywords : atrial fibrillation; early postoperative period; coronary bypass surgery; Department of Cardiovascular Surgery; secondary health care.
