高血压病是心脏血管疾病的一个主要的危险因子,主要是由于高级神经中枢调节血压功能紊乱所引起的,以动脉血压升高为主要表现。成人如舒张压持续在90 mm Hg以上,收缩压在140 mm Hg以上,一般即认为有高血压病。患者常有头痛、头晕、失眠、心悸、胸闷、烦躁和容易疲劳的感觉。血压≥180/110 mm Hg的严重的高血压很难控制,且伴发冠心病的危险性也增加,冠心病的危险性比正常血压≤120/80 mm Hg的人大5倍。高血压最大的危害是晚期并发脑血管病、心脏病和肾功能衰竭,严重影响人的生命。
Hypertension is a major risk factor for cardiovascular disease, mainly due to dysregulation of blood pressure regulation by the high-grade central nervous system, with arterial blood pressure as the main manifestation. Adults such as diastolic blood pressure continued to be above 90 mm Hg, systolic blood pressure above 140 mm Hg, generally considered to have hypertension. Patients often have headaches, dizziness, insomnia, palpitations, chest tightness, irritability and fatigue. Severe hypertension with a blood pressure of ≥180 / 110 mm Hg is difficult to control and the risk of coronary heart disease is also increased. The risk of coronary heart disease is 5 times greater than that of people with a normal blood pressure of ≤120 / 80 mm Hg. The greatest risk of hypertension is advanced cerebrovascular disease, heart disease and renal failure, seriously affecting human life.
