【摘要】 目的探讨增强型体外反搏对不稳定心绞痛患者心率变异性的影响。方法 100例不稳定心绞痛患者,随机分为常规治疗的对照组和常规治疗基础之上给予增强型体外反搏的观察组,每组50例,比较两组治疗总有效率和心率变异性改善情况。结果治疗前两组患者的PNN50、SDNN、r MSSD、SDANN、SDNNind无明显差异(P>0.05);在治疗后,观察组患者的PNN50、SDNN、r MSSD、SDANN、SDNNind明显高于对照组,差异均有统计学意义(P<0.05);观察组治疗的总有效率为88.00%,对照组总有效率为68.00%,观察组优于对照组,组间差异有统计学意义(P<0.05)。结论应用增强型体外反搏治疗不稳定心绞痛患者,效果明显且能改善心脏自主功能,有着重要的临床参考意义。更多还原

【Abstract】 Objective To investigate the effect of enhanced external counterpulsation( EECP) on heart rate variability in patients with unstable angina pectoris. Methods 100 patients with unstable angina pectoris were randomly divided into control group( n = 50) and observation group( n = 50). Patients in the control group accepted conventional treatment,and patients in the observation group accepted EECP on the base of conventional treatment. The total effective rate and improvement of heart rate variability were compared between two groups. Results Before the treatment,there was no significant difference in PNN50,SDNN,r MSSD,SDANN and SDNNind between two groups( P > 0. 05). After the treatment,PNN50,SDNN,r MSSD,SDANN and SDNNind in the observation group significantly increased compared with the control group( P < 0. 05). The total effective rate of the observation group was higher than that of the control group( 88. 00% vs 68. 00%,P < 0. 05). Conclusions EECP is highly effective and can improve autonomic heart function of patients with unstable angina pectoris,which provides a significant reference for clinical practice.更多还原
