8) Interestingly, the hypoxia that occurs during these apneic spells alone does not explain blood pressure elevations after obstructive apneas, (6) but is only one of the factors that, when added together, lead to hypertension in patients with OSA.

Inflammatory aspects of sleep apnea and their cardiovascular consequences
Cardiovascular mechanisms, such as increased blood pressure, heart rate and daytime muscle sympathetic nerve activity, which all are involved in the poor prognosis of HF patients were found to be reduced with CPAP In this context, using cardiac C-11 acetate positron emission tomography in HF patients with OSA, obstructive apneas were shown to depress cardiac function acutely while CPAP treatment was associated with improved cardiac function (50).
