【摘要】 目的 观察增强型体外反搏治疗冠心病不稳定型心绞痛的临床疗效。方法 将82例冠心病不稳定型心绞痛患者随机分为对照组和治疗组，对照组常规给予硝酸盐制剂、β受体阻滞剂、钙拮抗剂、双联抗血小板（阿司匹林和硫酸氯吡格雷）、他汀类调脂药物及低分子肝素等;治疗组在常规药物治疗基础上加用增强型体外反搏治疗，观察两组临床疗效及心电图变化。结果 治疗后总有效率治疗组85.7%, 对照组65.0%；心电图改善率分别为76.2%和52.5%，治疗组无严重不良反应发生。结论 增强型体外反搏治疗冠心病不稳定型心绞痛安全有效。�

【Abstract】 Objective To observe the effect of EECP on the treatment of UAP. Methods 82 cases with UAP were randomly divided into control group.Therapy group and the control group were treated with routine drugs such as Nitrites, β�blocker,calcium channel blocker, combined antiplatelet, statin and low molecular weight heparin，but the therapy group were treated with EECP in addition to the routine drugs,and the clinical effect and change of the electrocardiogram(ECG) were evaluated. Results The total effective rate and change rate of ECG were 85.7% and 76.2% in therapy group while 65.0% and 52.5% respectively in control group， the differences were of statistical sense (P0.05），具有可比性。�
1.2 治疗方法 对照组常规给予硝酸盐制剂、β受体阻滞剂、钙拮抗剂、双联抗血小板（阿司匹林和硫酸氯吡格雷）、他汀类调脂药物及低分子肝素等；治疗组在常规药物治疗基础上加用EECP， 反搏气囊充气压力取0.35~0.45kg/cm�2,1次/d, 1 h/次，12d为一疗程, 连续治疗3个疗程，观察治疗后心绞痛症状改善和心电图变化以及不良反应发生情况。�
1.3 疗效评定�
1.3.1 心绞痛疗效评定标准：显效:心绞痛症状发作次数及硝酸甘油耗量减少80%以上；有效：心绞痛症状发作次数及硝酸甘油耗量减少50%~80%；无效：心绞痛症状发作次数及硝酸甘油耗量减少不到50%。�
1.3.2 心电图疗效评定标准 显效：静息心电图缺血性改变恢复正常；有效：心电图缺血性下降的ST段回升1.0 mm以上但未达到正常水平或主要导联的倒置T波变浅达50%以上或T波由平坦转为直立；无效：达不到上述指标者。�
1.4 统计学方法 应用SPSS 13.0软件进行统计学处理，计数资料采用χ�2检验，计量资料采用t检验, P 对照组408（20.0）13（32.5）19（47.5）21（52.5）注：与对照组比较�*P
