简要总结

Recent evidences suggest that obstructive sleep apnea (OSA) can contribute to cardiovascular disease even in the absence of hypertension. However, there are few data regarding the impact of OSA on the sympathetic system in apparently normotensive patients with OSA as well as the impact of treatment with continuous positive airway pressure in different sites of activation (heart, peripheral nerves and circulating catecholamines)

结局指标

主要结局

improvement in sympathetic activity in muscle sympathetic nerve activity (MSNA)

时间窗: 3 months

Improvement in MSNA will be quantified as burst frequency over time (bursts per minute) and as burst frequency corrected for heart rate values (bursts per 100 heartbeats)in the begining and after 3 months.

次要结局

  • improvement in sympathetic activity evaluated in different sites of activation(3 months)
