Molecular mechanisms of chronic intermittent hypoxia and hypertension.
Obstructive sleep apnea (OSA) is characterized by episodes of repeated airway obstruction resulting in cessation (apnea) or reduction (hypopnea) in airflow during sleep. These events lead to intermittent hypoxia and hypercapnia, sleep fragmentation, and changes in intrathoracic pressure, and are associated with a marked surge in sympathetic activity and an abrupt increase in blood pressure. Blo...
متن کاملMechanisms of intermittent hypoxia induced hypertension
Exposing rodents to brief episodes of hypoxia mimics the hypoxemia and the cardiovascular and metabolic effects observed in patients with obstructive sleep apnoea (OSA), a condition that affects between 5% and 20% of the population. Apart from daytime sleepiness, OSA is associated with a high incidence of systemic and pulmonary hypertension, peripheral vascular disease, stroke and sudden cardia...
متن کاملChronic intermittent hypobaric hypoxia attenuates monocrotaline-induced pulmonary arterial hypertension via modulating inflammation and suppressing NF-κB /p38 pathway
Objective(s): Inflammation is involved in various forms of pulmonary arterial hypertension (PAH). Although the pathophysiology of PAH remains uncertain, NF-κB and p38 mitogen-activated protein kinase (p38 MAPK) has been reportedto be associated with many inflammatory mediators of PAH. This study aimed to evaluate the effect of chronic intermittent hypobaric hypoxia (CIHH) on pulmonary inflammat...
متن کاملCarotid body potentiation during chronic intermittent hypoxia: implication for hypertension
Autonomic dysfunction is involved in the development of hypertension in humans with obstructive sleep apnea, and animals exposed to chronic intermittent hypoxia (CIH). It has been proposed that a crucial step in the development of the hypertension is the potentiation of the carotid body (CB) chemosensory responses to hypoxia, but the temporal progression of the CB chemosensory, autonomic and hy...
متن کاملChronic intermittent hypoxia induces atherosclerosis.
RATIONALE Obstructive sleep apnea, a condition leading to chronic intermittent hypoxia (CIH), is associated with hyperlipidemia, atherosclerosis, and a high cardiovascular risk. A causal link between obstructive sleep apnea and atherosclerosis has not been established. OBJECTIVES The objective of the present study was to examine whether CIH may induce atherosclerosis in C57BL/6J mice. METHO...
