中文摘要 | 為了瞭解是否可由心率動態預測糖尿病患之視網膜病變,50位糖尿病患者參與本研究,依據其視網膜檢查結果將視網膜病變程度分為四級。參與者無心臟節律的病變,皆呈現竇房脈。各組之年齡、性別分佈、收縮動脈壓和舒張動脈壓並無差異。每位受試者接受五分鐘的心電紀錄,並由電腦程式進行非線性與線性分析,前者包括Correlation Dimension (CD), Approximate Entropy (ApEn),與Largest Lyapunov Exponent (LLE),後者包括平均心率週期 (RR)、心率標準差 (SD)、低頻功率 (LF, 0.04-0.15 Hz)、高頻功率 (HF, 0.04-0.15 Hz),與低/高頻功率比值(LF/HF)。相較於第一級無視網膜病變患者,第二級輕度視網膜病變者所有HRV分析皆差無顯著差異。RR,LF和HF於第四級重度視網膜病變者顯著下降。ApEn,CD與LLE同樣於第四級顯著下降,然而LLE在第三級病變組也有顯著變化。我們認為多種心率變異性之線性和非線性分析法皆能反應糖尿病患重度視網膜病變之發生,尤其以非線性之LLE有最佳之靈敏度。 |
英文摘要 | To explore whether diabetic retinopathy can be predicted by heart rate dynamics, 50 diabetic patients were enrolled in this study. They were classified into four groups according to the severity of retinopathy as diagnosed by fundus examination. The four groups did not differ in age, sex distribution, systolic and diastolic arterial pressure statistically. The participants had normal sinus rhythms, and five minutes of ECG signals were recorded in daytime while they were lying quietly. Computer analysis accomplished various linear and nonlinear estimations of heart rate variability (HRV), including mean (RR) and standard deviation (SD) of R-R intervals, low-frequency power (LF, 0.04-0.15 Hz), high frequency power (HF, 0.15-0.4 Hz), LF to HF ratio (LF/HF), correlation dimension (CD), approximate entropy (ApEn), and largest Lyapunov exponent (LLE). Compared with the no retinopathy group (group 1), the mild retinopathy group (group2) did not exhibit evident change in all parameters. However, the severe retinopathy group (group 4) had significantly lower RR, LF, HF, CD, ApEn, and LLE. It is noteworthy that only LLE altered significantly in the median retinopathy group (group 3). We concluded that severe retinopathy in diabetic patients can be indicated by various linear and nonlinear analyses of HRV, in which the nonlinear LLE has the best sensitivity. |
