Description
Summary:Background Bariatric surgery has been shown to improve hyperlipidemia, decreasing the need for statin medications. Although maintaining statin therapy post-surgery for those with a history of atherosclerotic cardiovascular disease (ASCVD) is advised, it is uncertain if discontinuation risks differ between those with and without ASCVD history. Aim The study aims to analyze the rate and reasons for statin cessation post-bariatric surgery in the US using real-world data. Methods Using the TriNetX electronic medical records network from 2012 to 2021, the study involved patients aged 18 or older on statins at the time of bariatric surgery. They were categorized into primary and secondary prevention groups based on prior ASCVD. Statin discontinuation was defined as a 90-day gap post the last statin dosage. The Cox model assessed factors influencing statin cessation. Results Seven hundred and thirty-three statin users undergoing bariatric surgery were identified, with 564 (77%) in primary prevention. Six months post-surgery, 48% of primary prevention patients and 34.5% of secondary ones stopped statins. Primary prevention patients had a 30% higher likelihood of cessation compared to secondary prevention (hazard ratio, 1.30; 95% CI, 1.06–1.60) as shown by multivariable analysis. Conclusions Post-bariatric surgery, primary prevention patients are more likely to discontinue statins than secondary prevention patients. Graphical Abstract
