Hypertensive patients with poorly controlled blood pressure can have a stroke, either an acute cerebral hemorrhage or an acute cerebral infarction. When blood pressure rises significantly, cerebral arteries are prone to rupture and acute cerebral hemorrhage will occur, and the most commonly ruptured arteries are the middle cerebral artery or the small arteries in the basal ganglia region. Hypertensive patients if the blood pressure control is not good, easy to cause cerebral atherosclerosis, long-term atherosclerosis will cause plaque rupture, resulting in thrombosis, causing cerebral artery blockage, acute cerebral infarction, hypertensive patients usually need to actively lower blood pressure treatment, to avoid the occurrence of cerebral stroke.
