【摘要】 目的:分析冠心病心律失常治療中胺碘酮聯(lián)合美托洛爾的療效及心率變異性(HRV)的影響。方法:選取73例冠心病心律失?;颊唠S機分為對照組(35例,基礎(chǔ)治療+胺碘酮)、觀察組(38例,對照組治療方案+美托洛爾)。比較用藥前后兩組的HRV指標,對比兩組的臨床療效及副作用。結(jié)果:用藥前兩組低頻功率(LF)、高頻功率(HF)、極低頻功率(VLF)、NN間期標準差(SDNN)、NN間期標準差的均值(SDNNI)、相鄰NN間期差>50 ms的心搏數(shù)百分比(PNN50)比較差異無統(tǒng)計學(xué)意義(P>0.05),用藥后兩組均顯著提高,且觀察組顯著高于對照組,差異均有統(tǒng)計學(xué)意義(P<0.05);觀察組臨床總有效率高于對照組,差異有統(tǒng)計學(xué)意義(P<0.05);兩組副作用發(fā)生率比較差異無統(tǒng)計學(xué)意義(P>0.05)。結(jié)論:冠心病心律失常治療中胺碘酮聯(lián)合美托洛爾可改善患者HRV指標,提升臨床療效,且不會造成副作用的明顯增多。

【Abstract】 Objective:To analyze the efficacy of Amiodarone combined with Metoprolol in the treatment of arrhythmia in coronary heart disease and its effect on HRV.Method:A total of 73 patients with coronary heart disease and arrhythmia were randomly divided into control group(35 cases,basic treatment+Amiodarone) and observation group(38 cases,control group treatment+Metoprolol).The heart rate variability index between the two groups before and after medication,the clinical efficacy and side effects of the two groups were compared.Result:There were no significant differences in low frequency power(LF),high frequency power(HF),very low frequency power(VLF),NN interval standard deviation(SDNN),NN interval standard deviation(SDNNI) and adjacent NN interval difference>50 ms between the two groups before treatment(P>0.05),which were significantly increased after treatment(P<0.05),of which the observation group were significantly higher than those of the control group(P<0.05).The total clinical effective rate of the observation group was significantly higher than that of the control group(P<0.05).There was no significant difference in the incidence of side effects between the two groups(P>0.05).Conclusion:Amiodarone combined with Metoprolol in patients with coronary heart disease arrhythmia can improve the heart rate variability index and improve clinical efficacy without causing a significant increase in side effects.

冠心病是常見心血管疾病,在當(dāng)前老齡化社會背景下發(fā)病率逐漸提高,且部分患者伴有心律失常[1]。胺碘酮與美托洛爾均為冠心病心律失常治療中常用藥物,臨床上對兩者聯(lián)用的相關(guān)研究較多,但關(guān)于兩者聯(lián)用對心率變異性(HRV)的影響研究尚少。HRV是對心臟自主神經(jīng)功能進行評價的無創(chuàng)性指標,在預(yù)測心血管疾病預(yù)后、評價藥物效果上具有重要意義[2]。為此,本研究將分析冠心病心律失常治療中胺碘酮聯(lián)合美托洛爾的療效及對其HRV的影響,現(xiàn)做如下報道。
