舒张压和收缩压的持续性升高可分为原发性(特发性)高血压和继发性高血压(占10—15％),尽管高血压的原因不同其血管的改变是类似的,而其严重性是因高血压的升高速度和持续的时间而决定的。良性高血压的死亡多由于心衰和脑血管疾患,因肾衰致死甚少,恶性高血压占高血压患者之5％,常见于较轻年龄组30—40岁,多因肾衰而死亡。
Sustained increases in diastolic and systolic blood pressure can be divided into primary (idiopathic) and secondary hypertension (10-15%), although their vascular changes are similar for different causes of hypertension , And its severity is due to the rate of hypertension and the duration of the decision. Mortality of benign hypertension and more due to heart failure and cerebrovascular disease, death due to renal failure rarely, malignant hypertension accounts for 5% of patients with hypertension, common in the younger age group 30-40 years old, mostly due to renal failure and death.
