摘要 脉压(pulse pressure,PP)升高被越来越多的研究证实是心脑血管疾病,特别是冠脉疾病的危险因素,通常评价血压状况的4种血压测量指标是指收缩压(SBP)、舒张压(DBP)、PP和平均血压(MBP)[1,2].PP值为SBP与DBP之差,PP差增大说明大动脉血管顺应性降低,僵硬度增加,是反映血管壁厚/管腔直径比值的一个有意义的指标,因此,PP升高可增加心、脑血管疾病的危险,是冠心病(CHD)、脑卒中及左心室肥厚(LVH)等发生的有力指征,PP的测量包括常规的肱动脉血压计、动态血压监测、内动脉压记录和特殊部位的测量等.PP的作用独立于其他血压测量值,特别是MBP.临床医生和保健医生多习惯看到SBP的重要性,特别是老年人,但最近的流行病学研究强调了PP作为老年人心脑血管事件预报因子的重要性[3].
