AngiotensinⅡ (AngⅡ) is the most widely known vasoconstrictor. It is not only a vasoconstrictor, but also a growth-promoting factor of vascular smooth muscle proliferation. Animal experiments suggest that AngⅡ as an independent risk factor for vascular damage may lead to stroke directly through the mechanism of vascular toxicity, involved in the process of cerebral ischemia-reperfusion injury. chlorine
