摘　　要：目的分析有氧运动对老年顽固性高血压患者心血管自主神经功能的影响。方法 110例老年顽固性高血压患者,按照治疗模式不同分为对照组和干预组,各55例。对照组患者按照常规治疗模式进行治疗,干预组患者在常规治疗基础上实施有氧运动训练干预。比较两组患者治疗前后收缩压(SBP)、舒张压(DBP)、心率(HR)、心率变异性(HRV)指标。结果治疗前,两组HR、SBP、DBP比较差异无统计学意义(P>0.05);治疗后,干预组HR为(73.1±4.9)次/min、SBP为(138.95±8.38)mm Hg(1mm Hg=0.133 kPa)、DBP为(91.42±4.83)mm Hg,均低于对照组的(80.1±5.2)次/min、(147.12±10.85)mm Hg、(96.45±5.60)mm Hg,差异有统计学意义(P<0.05)。治疗前,两组总功率(TP)、高频功率(HF)、标准化高频功率(HFn)、低频功率(LF)、标准化低频功率(LFn)、低频/高频功率(LF/HF)比较差异无统计学意义(P>0.05);治疗后,干预组TP和HF高于对照组, LF/HF低于对照组,差异有统计学意义(P<0.05)。结论针对老年顽固性高血压患者实施有氧运动训练,有助于不断改善和调整交感神经、迷走神经张力,及时调整心血管自主神经功能失衡情况,提升压力反射作用,促进患者血压持续下降,提升生存质量,是一种科学有效的运动干预模式,在临床可以进行进一步的探索应用。Objective To analyze the effect of aerobic exercise on cardiovascular autonomic function in elderly patients with refractory hypertension. Methods A total of 110 elderly patients with refractory hypertension were divided by different treatment modes into control group and intervention group, with 55 cases in each group. The control group was treated with conventional mode, and the intervention group was treated with aerobic exercise training intervention on the basis of the control group. Comparison were made on systolic blood pressure(SBP), diastolic blood pressure(DBP), heart rate(HR), heart rate variability(HRV) index before and after treatment between the two groups. Results Before treatment, both groups had no statistically significant in HR, SBP and DBP(P>0.05). Before intervention, the intervention group had lower HR as(73.1±4.9) times/min, SBP as(138.95±8.38) mm Hg(1 mm Hg=0.133 kPa) and DBP as(91.42±4.83)mm Hg than(80.1±5.2)times/min,(147.12±10.85)mm Hg and(96.45±5.60)mm Hg in the control group, and their difference was statisticallysignificant(P<0.05). Before treatment, both groups had no statistically significant in total power(TP), high frequency power(HF), standardized high frequency power(HFn), low frequency power(LF), standardized low frequency power(LFn), low frequency/high frequency power(LF/HF)(P>0.05). After treatment, the intervention group had higher TP, HF than the control group, and lower LF/HF than the control group. Their difference was statistically significant(P<0.05). Conclusion Aerobic exercise training for elderly patients with refractory hypertension helps to continuously improve and adjust tension of sympathetic and vagal nerves, timely adjust the cardiovascular autonomic imbalance, improve the pressure reflex, promote the continuous decline of blood pressure, and improve the quality of life. It is a scientific and effective exercise intervention model, and can be further explored and applied in clinical practice.
