Hypertension and cerebrovascular diseases of the relationship

Hypertension is the primary brain disease risk factors. According to reports, the United States cerebral infarction in patients with hypertension incidence rate is the normal two or three times. Japan is the world's highest incidence of cerebrovascular disease of the country, hypertension patients suffering from cerebrovascular disease is the normal 13.1 times. It was reported in China, 80 percent of cerebrovascular disease and hypertension-related people, of which 86 percent of cerebral hemorrhage and 71 percent of cerebral infarction have a history of hypertension, but no symptoms of high blood pressure and cerebrovascular diseases in the blood pressure is normal to the 4 Times, while in the study also found that both systolic or diastolic blood pressure increased, the risk of cerebral vascular disease are great. Systolic blood pressure> 19.4 kPa (1 50mmHg), in the relative risk of cerebral vascular disease, is the systolic blood pressure ≤ 19.4 kPa of 28.8 times, and diastolic blood pressure> 12.0 kPa (90mmHg), is the diastolic blood pressure ≤ 12.0 kPa 19 times All this fully shows that hypertension is an important cerebral vascular disease risk factors. Hypertension caused cerebral vascular disease mechanisms, mainly to accelerate the brain caused by arteriosclerosis. As a long-term hypertension can lead to arterial wall in small lesions, lumen stenosis, endometrial thickening, when the cerebral vascular lumen further stenosis or occlusion, can hypoxic ischemic brain tissue in case of cerebral thrombosis. Hypertension can cause artery walls transparent kind of small change, cellulose necrosis, forming tiny aneurysm. When blood pressure surge, this will harden the fragile vessel has been broken, and a cerebral hemorrhage. Effective control of blood pressure, can significantly reduce the incidence of cerebrovascular disease, and antihypertensive drug calcium antagonist, cerebral vascular expansion, the protection of brain cells, the ability of red blood cells, such as deformation, and the buck has a good effect, according to Selection of the situation, the commonly used drugs nimodipine, nitrendipine, nicardipine and equality.
