چکیده
Cardiovascular and cerebrovascular diseases are the most common diseases in industrialized societies. The main objectives of this article were to summarize the physiological effects of sleep apnea on the circulatory system and to review how treatment of this condition influences cardiovascular disease. Acute sleep apnea has a number of hemodynamic consequences, such as pulmonary and systemic hypertension, increased ventricular afterload and reduced cardiac output, all of which result from sympathetic stimulation, arousal, alterations in intrathoracic pressure, hypoxia and hypercapnia. When chronic, sleep apnea-hypopnea syndrome is associated with systemic hypertension, ischemic heart disease, congestive heart failure, and Cheyne-Stokes respiration in patients with congestive heart failure. Nocturnal treatment with continuous positive airway pressure decreases both the number of central apneic episodes and blood pressure in patients with sleep apnea-hypopnea syndrome and arterial hypertension.

OBJECTIVE To investigate the dynamics of the synchronization between heart rate variability and sleep electroencephalogram power spectra and the effect of sleep apnea-hypopnea syndrome. METHODS Heart rate and sleep electroencephalogram signals were recorded in controls and patients with sleep apnea-hypopnea syndrome that were matched for age, gender, sleep parameters, and blood pressure. Spec...
