BACKGROUND: In this study, we planned to determine the frequency of postoperative AF and its related parameters in morbidly obese patients who underwent bariatric surgery.
METHODS: The study included 300 patients with morbidly obese who had no history of AF and underwent successful bariatric surgery. Routine anamnesis, physical examination and laboratory parameters of the patients were recorded. Patients with postoperative AF were detected. The participants were grouped as patients with and without AF.
RESULTS: Postoperative AF occurred in 19 (6.3%) patients. Age, BMI and LAd diameter parameters independently determined the presence of AF. When the ROC curve was performed to identify patients with AF, the area under the ROC curve was found to be 0.841, 0.785 and 0.902 for age, BMI and LAd diameter, respectively. According to this analysis, 50 years for age, 43 kg/m2 for BMI and 40 mm for LAd were used to determine patients with AF with acceptable sensitivity and specificity (>70% each).
CONCLUSIONS: The most important determinants of postoperative AF are age, LAd and basal BMI. Therefore, morbidly obese patients with LAd >40 mm, BMI >43 kg/m2 and >50 years of age should be followed up more closely for postoperative AF development and preoperative precautions should be taken to prevent AF development.
