Background: The population undergoing bariatric surgery (BaS) has many cardiovascular risk factors that can lead to significant perioperative cardiovascular morbidity.
Objectives: We aimed to examine trends in the incidence of major adverse cardiovascular and cerebrovascular events (MACCE) after BaS.
Setting: Academic Hospital, United States METHODS: We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data registry for patients aged ≥18 years undergoing laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) from 2015 to 2019. Data on demographics, co-morbidities, and type of procedure were collected. MACCE was defined as a composite variable including perioperative acute myocardial infarction (AMI), cardiac arrest requiring cardiopulmonary resuscitation, acute stroke, and all-cause mortality. We utilized the Cochrane-Armitage and Jonckheere-Terpstra tests to assess for significant trend changes throughout the years.
Results: A total of 752,722 patients were included in our analysis (LSG = 73.2%, LRYGB = 26.8%). Postoperative MACCE occurred in 1058 patients (.14%), and was more frequent in patients undergoing LRYGB (.20%). The frequency of MACCE declined from .17% to .14% (P = .053), driven by a decline in the frequency of AMI (.04% to .02%, P = .002), cardiac arrest (.05% to .04%, P = .897), and all-cause death (.11% to .08%, P = .040), but with an increase in perioperative stroke (.01% to .02%, P = .057).
Conclusion: The overall risk of MACCE after BaS is .14% and has been declining in the last 5 years. This trend is likely multifactorial and further analysis is necessary to provide a detailed explanation.
