有些老年高血压患者,常常表现为收缩压(高压)升高,而舒张压(低压)正常或降低,老年高血压患者中约有一半属于上述这种类型。医学上将收缩压持续高于160毫米汞柱和舒张压持续低于90毫米汞柱,称为单纯收缩期性高血压病。现在认为,就发生心、脑血管病的危险性而言,收缩压升高和脉压差增大,要比舒张压升高更
Some elderly hypertensive patients, often manifested as systolic blood pressure (hypertension) increased, while diastolic blood pressure (low pressure) normal or decreased, about half of elderly hypertensive patients are of this type. Medically systolic blood pressure is consistently above 160 mmHg and diastolic blood pressure is consistently below 90 mmHg, referred to as isolated systolic hypertension. Now that the risk of heart disease, cerebrovascular disease, systolic blood pressure and pulse pressure increase, higher than the increase in diastolic blood pressure
