Research Uncovers New Mechanism for Angiotensin II in Brain Hemorrhage

A Nature Communications study identified a novel receptor-independent mechanism where Angiotensin II directly binds to antithrombin, activating a heparin-like effect. This disrupts coagulation and intensifies cerebral bleeding in hypertensive intracerebral hemorrhage (ICH), offering crucial insights into the 'thrombosis-hemorrhage paradox.' This discovery could inform new therapeutic strategies for ICH.
