动脉瓣关闭不全、主动脉硬化、甲亢等。1、脉压差定义收缩压与舒张压之间的压差值称为脉压差，正常值约为40毫米汞柱。/iknow-pic.cdn.bcebos.com/d01373f082025aaf57d7ba77f7edab64024f1aa1"target="_blank"帆禅>/iknow-pic.cdn.bcebos.com/d01373f082025aaf57d7ba77f7edab64024f1aa1?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"wqktp="https://iknow-pic.cdn.bcebos.com/d01373f082025aaf57d7ba77f7edab64024f1aa1"/>2、影响因素：（1）患高血压及动脉硬化，致使动脉壁弹性减弱，收缩压升高，而舒张压降低；（2）长期患高血压，致使心肌超负荷运转，造成心脏扩大或动脉瓣关闭不全；（3）患甲状腺机能亢进（甲亢）或严重贫血。3、治疗方法（1）治疗上因老年人血压调节功能减退，用降压药时要从小剂量开始，达到有效治疗剂量后再维持治疗，以后根据情况调整剂量。（2）可选用时效长、降压稳、副作用小、对心脑血管有保护作用的药物，如依那普利、培哚普利、硝苯地平控释片等。（3）除药物治疗外，保持健康的生活方式对防治高血压也很重要，饮食上应低盐、低脂，避免精神刺激，控制体重，并要适当运动。（4）同时应检查有无血糖、血早歼脂增高的情况，并积极防治。/iknow-pic.cdn.bcebos.com/8644ebf81a4c510f967825a66c59252dd52aa5ca"target="_blank"态睁尘>/iknow-pic.cdn.bcebos.com/8644ebf81a4c510f967825a66c59252dd52aa5ca?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"wqktp="https://iknow-pic.cdn.bcebos.com/8644ebf81a4c510f967825a66c59252dd52aa5ca"/>
