Bariatric Surgery Evaluation and Assessment of Treatment Efficacy - Intervention Trial

The goal of this clinical trial is to evaluate if a bariatric surgery strategy will improve clinical endpoints, cardiac parameters and functional status in patients with obesity (with BMI 32-40 kg/m2) and symptomatic HF with preserved or mildly reduced LVEF in combination with AF, as compared to standard of care. Patients will be randomized to either the Intervention group receiving bariatric surgery including an intensive pre- and postoperative treatment scheme or to the control group receiving standard of care.
