Abstract:
Objective To evaluate the predictive value of Holter ECG recordings for patients with moderate-severe obstructive sleep apnea and hypopnea syndrome ( OSAHS ) . Methods Holter recordings was performed in 76 patients who were diagnosed OSAHS by polysomnography( PSG) within one month from Jan. 2008 to July 2009 in our hospital. Twenty-eight patients were identified as mild OSAHS (AHI≤20) and forty-eight patients were moderate-to-severe OSAHS ( AHI >20). The indexes of heart rate variability (HRV) , total scores of thirteen sleep apnea risk indexes of Holter recordings and BMI were analyzed by bivariate Logistic regression analysis. Results Clinical features ( eg. Gender, age, complicated with hypertension,coronary heart disease, diabetes mellitus, hyperglycemia, and taken β-blocker) , total scores, the sum of thirteen sleep apnea risk scores collected by Holter recordings (5. 64 ± 2. 33 vs. 6.42 ± 2. 22, respectively,P>0. 05 ) were similar between patients with mild OSAHS and moderate-to-severity OSAHS. VLF/Total Power>70% ,the difference of daytime/nighttime LF Power < -70 and BMI were independent predictors of moderate-to-severe OSAHS with OR 3. 98 (1. 087 - 14. 596), 3. 69 (1. 106 - 12. 285) and 1. 28 (1. 062 - 1. 544), respectively (all P < 0. 05). Conclusions VLF/Total Power and the difference of daytime/nighttime LF Power and BMI could be used as screening parameters to recognize patients with moderate-to-severe OSAHS.
