摘要
目的 观察厄贝沙坦对老年心力衰竭(CHF)患者心率变异性(HRV)的影响。方法 纳入2012年10月~2014年3月于解放军第253医院心内科住院确诊为CHF的患者32例,其中男性19例,女性13例,年龄65~76岁,平均(71±8.9)岁。同时将CHF患者随机分为两组,厄贝沙坦组(17例)和常规治疗组(15例)。常规治疗组按指南要求给予强心、利尿、扩血管及病因等标准治疗;厄贝沙坦组则在常规治疗的基础上加用厄贝沙坦,连续治疗8周。所有入选者均于治疗前后测定并计算HRV的各项时域及频域指标。时域指标包括正常R-R间期标准差(SDNN)、节段平均R-R间期标准差(SDANN)、正常R-R间期标准差平均值(SDNNindex)、相邻R-R间期差值均方根(RMSSD)、相邻R-R间期差值大于50 ms记数占总R-R间期数的百分比(PNN50);频域指标包括心率变异总功率(TP)、低频功率(LF)、高频功率(HF)、极低频功率(VLF)。结果 与治疗前比较,厄贝沙坦组治疗后时域指标SDNN、SDANN和RMSSD增加,频域指标中的TP、VLF、LF、HF也增加,差异有统计学意义(P均〈0.05)。厄贝沙坦组治疗后较常规治疗组时域指标中的SDNN[(77.3±29.4)ms vs.(71.5±31.2)ms]、SDANN[(78.1±25.3)ms vs.(65.8±29.6)ms]和RMSSD[(28.1±11.4)ms vs.(23.7±6.9)ms]增加,频域指标中的TP[(968.6±382.4)ms2 vs.(765.4±335.2)ms2]、VLF[(652.3±361.7)ms2 vs.(501.2±265.4)ms2]、LF[(251.3±77.1)ms2 vs.(191.2±69.0)ms2]、HF[(95.4±61.3)ms2 vs.(79.5±61.1)ms2]增加,差异有统计学意义(P均〈0.05)。结论 厄贝沙坦可以改善老年CHF患者的HRV,改善心脏自主神经功能的失衡。
Objective To observe the influence of irbesartan on heart rate variability (HRV) in elderly patients with congestive heart failure (CHF). Methods CHF patients (n=32, male 19, female 13, aged from 65 to 76 and average age=71±8.9) were chosen from Oct. 2012 to Mar. 2014, and randomly divided into irbesartan group (n=17) and control group (n=15). The control group was given routine treatment including cardiotonic, diuretic, vasodilative and etiological therapies, and irbesartan group was additionally given irbesartan for 8 w. The time-domain indexes and frequency-domain indexes were detected and calculated in all patients before and after treatment. The time-domain indexes included SDNN, SDANN, SDNN-index, RMSSD and PNN50, and frequency-domain indexes included TP, LF, HF and VLF. Results After treatment, SDNN, SDANN and RMSSD increased, and TP, VLF, LF and HF increased too in irbesartan group (all P〈0.05). After treatment, SDNN [(77.3±29.4) ms vs. (71.5±31.2) ms], SDANN [(78.1±25.3) ms vs. (65.8±29.6) ms] and RMSSD [(28.1±11.4) ms vs. (23.7±6.9) ms] increased, and TP [(968.6±382.4) ms2 vs. (765.4±335.2) ms2], VLF [(652.3±361.7) ms2 vs. (501.2±265.4) ms2], LF [(251.3 ±77.1) ms2 vs. (191.2±69.0) ms2] and HF [(95.4±61.3) ms2 vs. (79.5±61.1) ms2] increased in irbesartan group compared with control group (all P〈0.05). Conclusion Irbesartan can improve HRV and relieve the imbalance of autonomic nervous system in elderly patients with CHF.
