Enrolling 17,604 adults aged 45 or older with established cardiovascular disease and a BMI of 27 or higher (without diabetes), SELECT showed that semaglutide 2.4 mg reduced the composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke by 20% over a mean follow-up of nearly 40 months
Unlike other years, the 2022 EHBS used as its panel both respondents to either of the prior two years of EHBS (2020 and 2021) and also respondents to either of the prior two years of CHBS (2018 and 2020)
If it doesnt dissolve immediately, continue to gently swirl the vial or let it sit at room temperature for a few minutes
Study Strengths & Limitations Strengths: Large, international, double-blind RCT with adjudicated endpoints Comprehensive, repeated adiposity measures using standardised protocols Sophisticated statistical handling including multiple imputation models for missing data Pre-specified analysis with clear hypotheses Limitations: Predominantly White (77%) and male (63%) cohortgeneralisability to other populations requires confirmation Industry-funded (Novo Nordisk), though with independent academic oversight Post-randomisation analyses of weight/waist changes are observational and cannot prove causation The paradoxical association in placebo between weight loss and increased MACE suggests unintentional weight loss from comorbiditya key confounder The Bottom Line for Clinicians Semaglutide provides robust cardiovascular protection in patients with obesity and established CVD, independent of baseline adiposity and largely independent of weight-loss magnitude
