Summary
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)
Conditions
- Radionuclide Imaging (MIBG Scintigraphy)
- Exercise Test
- Blood Pressure Monitoring, Ambulatory
- Sympathetic Nerve Activity
- Catecholamines
