| 中文摘要 | 多囊性卵巢症候群患者相較於對照組,具有較高之窒息低息指數,然而其睡眠當中窒息低息的狀況與其心率變異性之關係則尚待研究。本研究受試者包括研究組14個實驗組思者與對照組11人(身體質量指數各為21.51±0.63與21.27±0.66),接受整晚之睡眠多項生理檢查,並評估胰島素抗性。心率部份經頻譜分析檢視不同睡眠階段的短期心率變異性,及6小時長期心率變異性。結果見實驗組之窒息低息指數與覺醒指數,於非快速動眼期時比對照組高(0.032±0.028vs.0.698±0.243p=0.004; 11.45±0.864vs.8.636±0.847p=0.0484)。而實驗組之長期心率變異性中,心跳間隔的三角底寬較低(303.9±19.23vs355.9±10.97p=0.0484)。於校正年齡、體脂肪百分比、血清男性荷爾蒙後,其與窒息低息指數為負相關,亦與高敏感C反應蛋白為負相關;快速動眼期之窒息低息指數則與高敏感C反應蛋白正相關。即使在患者未肥胖時,多囊性卵巢症候群具有較差之心臟交感神經功能,從而影響其睡眠當中的心率變異性。 |
| 英文摘要 | Background: Patients with polycystic ovary syndrome (PCOS) have a higher apnea-hypopnea index (AHI) than did controls. The relationship between heart rate variability (HRV) changes and apneic-hypopneic events in non-obese women with PCOS during sleep is yet to be determined. Methods: All participants (14 untreated women with PCOS and 11 age-and BMI-controlled healthy women, with mean body mass indexes of 21.51±0.63 and 21.27±0.66 Kg/cm^2, respectively) underwent whole-night standard polysomnographic (PSG) monitoring and assessment of serum hormone and homeostasis model assessment of insulin resistance (HOMA-IR). Short-term HRV (in different sleep stages) and long-term HRV (6-hour sleep) were obtained by a power spectral analys is. Results: The AHI and arousal index during the non-rapid eye movement stage (AHI(subscript NREM) and ARI(subscript NREM) were both higher in non-obese women with PCOS than those in the control group (0.032±0.028 vs. 0.698±0.243 p=0.004; 11.45±0.864 vs. 8.636±0.847 p=0.045 Triangular interpolation of the NN interval histogram TINN) of long-term HRV in the PCOS group was also lower (303.9±19.23 vs. 355.9±10.97, p=0.0484) .TINN in all subjects was negatively correlated to the AHI, after adjusting for age, body fat percentage, and serum androgens. TINN had negative relation with highly sensitive C-reactive protein (hsCRP) while AHIREM was positively related to hsCRP. Conclusions: Non-obese patients with PCOS showed poorer long-term TINN during sleep compared to the controls. The TINN was related to AHI and hsCRP. PCOS patients suffered from worsened cardiac nerve autonomous function that could lead to long-term cardiovascular risk during sleep even when they are not obese. |
