Mild obstructive sleep apnoea (OSA) and arterial hypertension in the EuropeanSleep Apnoea Database (ESADA) cohort study

Background: Mild obstructive sleep apnoea (OSA) is highly prevalent, however its association with important clinical outcomes like arterial hypertension remains unknown. Aims and Objectives: To investigate the association between mild OSA and arterial hypertension in the European Sleep Apnoea Database (ESADA) cohort after adjusting for relevant confounding factors. Methods: A multicentric sample of 4974 adults from the ESADA cohort who showed simple snoring or mild OSA at cardiorespiratory polygraphy was studied. We compared the predictive value of mild OSA (AHI 5- Results: Arterial hypertension prevalence was 37% in mild OSA patients (n=2457) compared to 20% in non-apnoeic snorers (n=2517, p Conclusions: Mild OSA was associated with an independent 43% risk increase for arterial hypertension in this large, multicentric clinical patient cohort.
