If you are a person with high blood pressure, beware, because high blood pressure is one of the most dangerous factors that can cause a stroke. According to statistics, people with high blood pressure are more likely to have a stroke than people without high blood pressure, and the former are four to seven times more likely to have a stroke than the latter. Chronic hypertension increases the tension of the blood vessels, which means that the blood vessels are “tense”. Over time, the blood vessel wall will degenerate, while the arterial lining is damaged, also prone to atherosclerosis. On the basis of the above-mentioned lesions, high and low blood pressure can further damage the cerebral arteries, which can easily cause cerebral artery rupture or form thrombus blocking cerebral arteries on the basis of atherosclerosis, resulting in stroke. Some people feel that high blood pressure does not bring physical discomfort, and have been “carrying” unwilling to take medication. In fact, the severity of symptoms in patients with hypertension is not necessarily proportional to the degree of blood pressure.
