Safety of bariatric surgery in patients with previous acute coronary events or heart failure: nationwide cohort study.
Observational study in BJS open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMetabolic (bariatric) surgery for patients with severe obesity and pre-existing heart disease has been reported to reduce the risk for cardiovascular events and mortality; however, concerns of short- and mid-term complications may limit the utility of metabolic surgery for these patients.
methodThis was an observational, nationwide, matched study, including all adult patients operated with a primary gastric bypass or sleeve gastrectomy procedure in Sweden from January 2011 until October 2020. Patients with or without previous acute coronary syndrome or heart failure were matched 1:5 using propensity scores. The primary outcome was serious postoperative complications, and secondary outcomes were the occurrence of any short-term complications, mid-term complications, weight loss, and health-related quality of life estimates after surgery.
resultsOf patients who underwent metabolic surgery, 1165 patients with previous acute coronary syndrome or heart failure and 5825 without diagnosed heart disease were included in matched analyses. No difference was seen between the groups at risk for serious postoperative complications within 30 days of surgery (OR 1.33, 95 per cent c.i. 0.95 to 1.86, P = 0.094), whereas heart disease was associated with an increased risk for cardiovascular complications (incidence 1.1 per cent versus 0.2 per cent, P < 0.001). No differences in overall mid-term complications, weight loss, or improvement of health-related quality of life were seen. Pre-existing heart disease was associated with an increased risk for bowel obstruction and strictures (OR 1.89, 95 per cent c.i. 1.20 to 2.99, P = 0.006).
conclusionPatients with severe obesity and heart disease undergoing metabolic surgery have an increased risk of postoperative cardiovascular complications compared with patients with severe obesity without heart disease. A careful preoperative cardiovascular work-up is needed but patients with severe obesity and heart disease should not be excluded from undergoing metabolic surgery.
