A randomized crossover trial of 108 habitual cannabis users found fewer premature atrial contractions on cannabis-use days than abstinence days. The short-term physiologic findings provide mechanistic insight but were not designed to evaluate long-term cardiovascular health outcomes.

Among more than 7,300 Swedish patients with Alzheimer’s disease and atrial fibrillation, NOAC use was associated with slower cognitive decline than warfarin or no anticoagulation. The observational findings did not establish causality but suggest potential differences in long-term cognitive outcomes.

In an observational target trial emulation of patients with atrial fibrillation and mitral stenosis, DOACs were associated with higher 1-year stroke risk than warfarin. Bleeding and all-cause mortality risks did not differ between groups.

A 16-year-old girl presented with acute aphasia and right-sided weakness consistent with a large-vessel stroke syndrome. Neuroimaging confirmed left middle cerebral artery occlusion, but the underlying etiology was not immediately apparent.

U.S. News expanded its 2026-2027 hospital rankings with new regional specialty evaluations in cancer and cardiovascular care while increasing recognition for regional hospitals. Rankings continued to emphasize risk-adjusted mortality, preventable complications, patient experience, and objective outcomes measures.

Researchers identified distinct neuronal populations within the heart’s intrinsic nervous system that regulate cardiac rhythm and stress responses in mice. The findings provide mechanistic insight into cardiac neurobiology, though human relevance remains uncertain.
