研究目的:

增强型体外反搏(Enhanced External Counter-pulsation,EECP)可改善外周动脉内皮功能,并引起血流介导的外周血管扩张。EECP在下肢动脉硬化闭塞症患者的疗效目前尚未有的相关研究。本课题拟通过入选LEASO中已经出现间歇性跛行(Intermittent claudication)患者行EECP治疗,讨论EECP对患者无痛最大步行距离(Pain-free walking distance,PWD)的影响,为LEASO的治疗提供新的无创策略。评估EECP治疗间歇性跛行的有效性及安全性。  

Objectives of Study:

Enhanced External Counter-pulsation (EECP) improves peripheral arterial endothelial function and induces blood flow-mediated peripheral vasodilation. However, its therapeutic efficacy in patients with Lower Extremity Arteriosclerosis Obliterans (LEASO) remains underexplored. This study aims to enroll LEASO patients presenting with intermittent claudication and administer EECP intervention to evaluate its impact on pain-free walking distance (PWD). The findings are expected to provide a novel non-invasive strategy for managing LEASO and to comprehensively assess the efficacy and safety of EECP in treating intermittent claudication.
