老年高血压病是指年龄≥60岁、收缩压(SP)≥21.3kpa(160mmHg)及(或)舒张压(DP)≥12.7kpa(95mmHg)者。该病分为两型:(1)红典型高血压,特点是DP≥12.7kpa,sp也相应升高;(2)收缩期高血压,特点是sp≥21.3kpa,DP<12.7kpa,<45岁者极少涉及此型。老年高血压病很少有急进性或恶性者,除肾血管性者(见乎都是肾动脉主干的粥样化阻塞)外,很少有其他继发性的。根据一项大规模的调查,我国≥60岁者的高血压患病率为20%其并发症的发生率及死亡率均高于低龄组高血压或同龄组非高血压者,同时老年患者的生理、病理状况与非老年者
Elderly hypertension is defined as age ≥60 years, systolic blood pressure (SP) ≥21.3kpa (160mmHg) and / or diastolic blood pressure (DP) ≥12.7kpa (95mmHg). The disease is divided into two types: (1) red typical hypertension, characterized by DP ≥ 12.7kpa, sp correspondingly increased; (2) systolic hypertension, characterized by sp ≥ 21.3kpa, DP <12.7kpa, <45 This type is rarely involved in the elderly. There are very few elderly hypertensive patients with acute or malignant, with the exception of renal vascular (seemingly the main atherosclerotic obstruction of the renal artery), there are few other secondary. According to a large-scale survey, the prevalence of hypertension ≥ 20 years old in our country is 20%, the incidence of complications and mortality were higher than those in the younger age group or non-hypertensive group in the same age group, Physiological, pathological conditions and non-elderly
