No symptoms of hypertension, cerebral vascular disease opportunity is normal blood pressure 4 times, at the same time, the study also found either systolic or diastolic blood pressure on cerebral vascular disease, the risk of large. Systolic blood pressure ( 1 >19.4kPa 50mmHg ), cerebral vascular disease in relative risk, is a systolic blood pressure < 19.4kPa 28.8 times, while diastolic pressure >12.0kPa ( 90mmHg ), is the diastolic pressure is less than 12.0kPa 19 times
Hypertensive cerebrovascular disease
The primary risk factors. According to the report, the United States of America in hypertensive patients with cerebral infarction incidence rate is 2 ~ 3 times the normal people. Japan is the world 's highest incidence of cerebrovascular disease, hypertension patients with cerebral vascular disease is 13.1 times the normal. In our country, people report, 80% of the cerebral vascular patients associated with hypertension, of which 86% of the cerebral hemorrhage and 71% cerebral infarction has a history of hypertension, and no symptoms of hypertension, cerebral vascular disease opportunity is normal blood pressure 4 times, at the same time, the study also found either systolic or diastolic blood pressure, on cerebrovascular disease risk have a great. Systolic blood pressure ( 1 >19.4kPa 50mmHg ), cerebral vascular disease in relative risk, is a systolic blood pressure < 19.4kPa 28.8 times, while diastolic pressure >12.0kPa ( 90mmHg ), is the diastolic pressure≤12.0kPa 19 times, all of which are fully described in the hypertensive cerebrovascular disease is a significant risk factor.
Hypertension caused by cerebrovascular disease mechanisms, is primarily accelerated arteriosclerosis caused by. As a result of long-term hypertension can lead to arterial lesions, luminal stenosis, intimal thickening, when cerebral vascular lumen further stenosis or occlusion, can make the brain ischemia hypoxia and cerebral thrombosis. Hypertension can also cause arteriolar wall hyalinization, fibrinoid necrosis, and the formation of small aneurysms. When blood pressure rises, can make this has hardened the fragility of the vascular rupture, and the occurrence of cerebral hemorrhage.
Effective control of blood pressure, can significantly reduce the incidence of cerebrovascular disease, and antihypertensive agents of calcium antagonists, a dilation of cerebral blood vessels, protecting brain cells, maintaining the erythrocyte deformability, and has a good effect of reducing blood pressure, can choose according to the circumstances, commonly used drugs with nimodipine, nitrendipine, nicardipine and so on.
