Does tirzepatide offer comparable cardiovascular safety to GLP-1 therapy in diabetes?

A large cardiovascular outcomes trial in high-risk adults with type 2 diabetes showed that a dual incretin therapy was noninferior to an established comparator for major adverse cardiovascular events over four years, with similar overall safety but more gastrointestinal side effects and no added cardiovascular benefit. Separate trials demonstrated that a single-bolus thrombolytic was as effective and safe as standard infusion therapy for acute ischemic stroke while simplifying workflows, and that vascular brain injury and inherited risk independently increase dementia risk, underscoring the importance of aggressive management of modifiable vascular factors.
