This study evaluated the effect of increased physical activity on high-frequency (HF) heart rate variability (HRV) during the first hour after sleep onset in patients with hypertension and/or stable angina pectoris. Physical activity and HF were measured using activity monitors and 24-hour Holter monitors at baseline and 6 months later. The physical activity increased in 28 patients (increase group) and decreased in 20 patients (decrease group) after 6 months. In this study, after 6 months, compared to the decreased physical activity group, the increased physical activity group showed a significant increase in the HF index during the first hour after sleep onset. Therefore, the increase in the HF index may have been due to the increase in physical activity. An increase in physical activity suggests that the quality of sleep early in the sleep cycle may be improved, which may affect the patient's prognosis.
本研究评估了高血压和/或稳定型心绞痛患者睡眠起始后 1 小时内增加身体活动对高频（HF）心率变异性（HRV）的影响。在基线和 6 个月后，使用活动监测器和 24 小时动态心电图监测器测量身体活动和 HF。6 个月后，28 名患者（增加组）的身体活动增加，20 名患者（减少组）的身体活动减少。在这项研究中，与身体活动减少组相比，身体活动增加组在睡眠起始后 1 小时内 HF 指数显著增加。因此，HF 指数的增加可能是由于身体活动的增加。身体活动的增加表明睡眠周期早期的睡眠质量可能得到改善，这可能会影响患者的预后。
