摘　　要：目的观察增强型体外反搏(EECP)对不稳定型心绞痛患者血浆脂蛋白磷脂酶A2(LP-PLA2)水平、血管内皮舒张功能的影响。方法选取来郑州大学第二附属医院就诊的100例已明确诊断的不稳定性心绞痛患者,随机分为常规药物治疗组(对照组n=49)和体外反搏组(观察组n=51,药物加体外反搏治疗,30 min/次,共30 d,总计60次)。入选对象均在入选当天及治疗结束当天检测血液中LP-PLA2水平,并用彩色多普勒超声检测肱动脉血流介导的血管舒张功能(FMD)及硝酸甘油片介导的血管内皮舒张功能(NMD)。结果观察组治疗后,LP-PLA2较治疗前下降,差异具有统计学意义(P <0.05),而FMD、NMD较治疗前均有升高,差异有统计学意义(P <0.05);对照组治疗后,LP-PLA2、内皮依赖型血管舒张功能及非内皮依赖型血管舒张功能较治疗前无明显变化(P> 0.05);组间观察发现,观察组FMD、NMD的提高程度较对照组明显(P <0.01),观察组的血浆LP-PLA2水平较对照组也有下降(P <0.01)。结论增强型体外反搏在血流切应力的作用下,可降低患者LP-PLA2水平,并改善血管内皮舒张功能。Objective To investigate the effect of enhanced external counterpulsation(EECP)on plasma lipoprotein phospholipase A2(LP-PLA2)levels,vascular endothelial diastolic function in patients with unstable angina. Methods One hundred patients with unstable angina treated in our hospital were randomly divided into routine treatment group(control group n = 49)and external counterpulsation group(observation group n = 51, routine treatment plus external counterpulsation therapy,60 min/time,a total of 30 times). All selected subjects were tested for LP-PLA2 levels on the day of enrollment and on the 30th day after treatment,and color Doppler ultrasonography was used to detect arterial blood flow-mediated vasodilation(FMD)and nitroglycerin-mediated vasodilation(NMD). Results After treatment in the observation group,LP-PLA2 decreased compared with before treatment,the difference was statistically significant(P < 0.05),but FMD,NMD were higher than those before treatment,which had statistical difference(P < 0.05). In control group treatment afterwards,LP-PLA2, endothelium-dependent vasodilatation and non-endothelium-dependent vasodilatation did not change significantly before treatment(P > 0.05). Observations between groups showed that the increase in FMD and NMD in the observation group was significantly greater than that in the control group. P < 0.01),plasma LP-PLA2 levels in the observation group also decreased compared with the control group(P < 0.05). Conclusion Enhanced external counterpulsation can reduce the level of LP-PLA2 in patients and improve endothelial diastolic function under the action of blood flow shear stress.
