Allocation of Semaglutide According to Coronary Artery Calcium and BMI

JACC Cardiovasc ImagingPublished

  • Prospective cohort study (secondary analysis of MESA) with modelled NNT
  • SELECT trial risk reductions applied to observed incidence rates

Authors' conclusion

Measurement of CAC may enhance value of care with weight loss dose semaglutide in those without diabetes or clinical CVD, improving allocation of a limited health care resource.
