High-dose GLP-1 receptor agonists and treatment of patients with higher baseline BMI are associated with a significantly increased risk of ventricular arrhythmias (VAs).

If you are taking a high dose of a GLP-1 medication (like the maximum weight-loss doses of Ozempic or Saxenda), especially if you have a higher body weight, there is a slightly increased risk of ventricular arrhythmias. Doctors should monitor these patients more closely. However, this risk is specific to high doses and higher BMI, not the standard doses used for diabetes.

Additionally, higher doses of GLP-1 RAs (RR 1.63, 95% CI 1.11–2.40) and higher baseline BMI (RR 1.60, 95% CI 1.04–2.48) might significantly increase the risk of VAs.

Why this rating

Meta-analysis of RCTs, but subgroup analysis sensitivity was noted (removing specific trials diminished significance).
