Postoperative atrial fibrillation complicates 8.4% of lung surgeries, with pneumonectomy and underlying cardiovascular disease being significant risk factors.
Answers are grounded in this paper and cite their sources.
May inform targeted monitoring after pneumonectomy or in patients with cardiovascular disease; hypothesis-generating pending prospective validation.
OBJECTIVE: The aim of this study was to determine which of the clinical parameters are the most valuable in predicting postoperative atrial fibrillation after lung surgery. MATERIALS AND METHODS: Retrospective analysis was carried out on 298 patients after pulmonary resection necessitated mainly by lung cancer. The following parameters were investigated: age and sex, disturbances of cardiac rhythm, history of ischemic heart disease, diabetes and atherosclerosis, NYHA classification and type of surgical procedure. In addition, the duration of surgery, variations in oxygen saturation, changes in systemic blood pressure and heart-rate were noted intraoperatively. Statistical analysis was performed using Fisher's exact test. RESULTS AND CONCLUSIONS: Atrial fibrillation occurred in 25 cases (8.4%) and more frequently after pneumonectomy (24%). Other factors contributing to atrial fibrillation after lung surgery were: history of ischemic heart disease, congestive heart failure, intraoperative cardiac arrest and the need for rethoracotomy.
