ARBs prevent stroke incidence by blocking the angiotensin II (AII), AT1 receptors preventing brain ischemia and allowing AII to stimulate the unoccupied AT2 receptors which improve brain ischemia. ACEIs, by reducing AII generation, are less effective in preventing stroke. This hypothesis provides ev ...
