研究发现高血压引起的动脉改变与衰老相似,表现为动脉硬化,主要导致动脉缓冲功能的减退和僵硬度的增加。脉搏波速度(PWV)是评价动脉僵硬度的经典指标之一,综合反应各种危险因素对血管的损伤,是心血管疾病危险率的独立预测因子,其预测价值越来越被认同[1]。本研究通过观察拉西地 Study found that hypertension caused by arterial changes and aging similar to the performance of atherosclerosis, mainly leading to decreased arterial cushioning function and increased stiffness. Pulse wave velocity (PWV) is one of the classic indexes to evaluate arterial stiffness. It is an independent predictor of the risk of cardiovascular disease by comprehensively reflecting the damage of various risk factors on blood vessels. Its predictive value is more and more recognized [1] . This study by observing Lasi ground
