短时运动对冠状动脉介入治疗术后冠心病患者肱动脉踝动脉脉搏波速度的影响

摘要

Objective To study the effect of short-term exercise on brachial ankle artery pulse wave velocity(baPWV) in patients with coronary artery disease after PCI. Methods Sixty-nine male patients with cornary artery disease after PCI were enrolled in this study. Their baPWV was measured 10 minutes after they underwent treadmill test with modified Bruce program. Results The mean arterial pressure and baPWV were significantly lower after exercise than before exer-cise(97. 26±11.51 mm Hg vs 91. 33 + 9. 64 mm Hg, 1421. 84 + 224.14 cm/s vs 1340.25 + 218. 16 cm/s,P<0. 01). The systolic pressure and diastolic pressure were lower after exercise than before exercise.but with no significant difference between them(P>0. 05). Conclusion Short-term exercise can effectively improve the arterial stiffness in patients with coronary artery disease.%目的 探讨短时运动对PCI术后冠心病患者肱动脉-踝动脉脉搏波速度(brachial-ankle artery pulse wave velocity,baPWV)的影响.方法 选择PCI术后常规复查的男性冠心病患者69例,平板运动试验采用改良Bruce方案,试验前及试验结束后10 min测量患者baPWV值.结果 患者短时运动后平均动脉压和baPWV值较运动前明显下降[(97.26±11.51)mm Hg vs(91.33±9.64)mm Hg(1 mm Hg=0.133 kPa),(1421.84±224.14) cm/svs (1340.25±218.16) cm/s],差异有统计学意义(P＜0.01)；收缩压和舒张压较运动前有所下降,但差异无统计学意义(P＞0.05).结论 短时运动可以有效改善冠心病患者的动脉僵硬度.
