Implication
Correlations between autonomic indices and SDB severity differ by sex and state; hypothesis-generating, prospective studies needed before clinical consideration.
Structured PICO
P
Population
288 non-smoking, normotensive adults free of cardiovascular disease and diabetes with high-quality ECG signals from the Sleep Heart Health Study (SHHS). 221 males, 67 females, age 46.1 to 74.9 years.
O
Outcome
Correlation between spectral indices of heart rate variability (HFP, LHR, HFPra, LHRra) and severity of sleep-disordered breathing (RDI)surrogate
Cardiac autonomic control indices correlate with sleep-disordered breathing severity, with the nature of these correlations significantly affected by gender and sleep-wake state.
