“…Only a few case reports [ 17 , 21 , 22 ], and one prior study [ 9 ] have been published to address this matter. Malik et al were the first to demonstrate that bradycardia is a notable outcome of bariatric surgery, and its association with the reduction in BMI.…”

Purpose The aim was to describe the frequency of bradycardia 12 years after Roux-en-Y gastric bypass (RYGB), relations to weight loss, patient characteristics, and the clinical impact. Materials and Methods The BAROPS study is a prospective observational study of patients who had follow-up > 10 years after RYGB. Patients with heart rate (HR) ≤ 50 bpm were compared to patients with HR > 50 bpm. Results After a mean observation period of 12 years, 32 of 546 patients (6%) had a HR ≤ 50 with a mean HR of 47.0 (2.8) bpm. The comparator group (192 patients) had a mean HR of 66.4 (10.2) bpm (p < 0.001). A higher proportion of the bradycardic vs. non-bradycardic patients (18.8% vs. 7.8% at baseline (p = 0.05) and 18.8% vs. 5.2% at end of study (p = 0.006)) used beta-blockers. Both groups had a significant reduction in heart rate from pre-surgery to end of observation. Percent total weight loss from baseline was negatively related to heart rate (p < 0.001), and smoking was positively related to heart rate (p = 0.014). Change in BMI from pre-surgery (p < 0.001) and hypertension at pre-surgery (p = 0.006) were significant predictors of change in heart rate. The only predictor of HR ≤ 50 was the use of beta-blockers (p = 0.010). There were no difference in bradycardia-related symptoms. Conclusion Six percent of patients had HR ≤ 50 bpm 12 years after RYGB, but there was no increased bradycardia-related symptoms in these patients. RYGB induced a significant reduction in HR, and heart rate and changes in heart rate 12 years after RYGB were related to the amount of weight loss. Graphical Abstract
