Sleep Apnea And Cardiovascular Disease

Desember 08, 2020

The pathophysiology of osa is characterized by repetitive occlusions of the posterior pharynx during sleep that obstruct the airway followed by oxyhemoglobin desaturation persistent inspiratory efforts against the occluded airway and termination by arousal from sleep. Emerging research highlights the complex inter relationships between sleep disordered breathing and cardiovascular disease presenting clinical and research opportunities as well as challenges.

Lofta Sleep Fact Untreated Sleepapnea Can Increase The Risk Of

Besides obesity contributing to sleep apnea sleep deprivation caused by sleep apnea can in an ongoing unhealthy cycle lead to further obesity dr.

Sleep apnea and cardiovascular disease. Likewise sleep apnea and hardening of the arteries atherosclerosis appear to share some common physiological characteristics further suggesting that sleep apnea may be an important predictor of cardiovascular disease. Sleep related breathing disorders are highly prevalent in patients with established cardiovascular disease. Although obstructive sleep apnea and cardiovascular disease have common risk factors epidemiologic studies show that sleep apnea increases risks for cardiovascular disease independently of individuals demographic characteristics i e age sex and race or risk markers i e smoking alcohol obesity diabetes dyslipidemia atrial fibrillation and hypertension.

Patients presenting to cardiology clinics have a high prevalence of obstructive osa and central sleep apnea associated with cheyne stokes respiration csa csr. 2 current evidence regarding the association between osa and hypertension stroke ischemic heart disease heart failure atrial. This content was created by the national sleep foundation.

Reasons for this include absence of apnea related symptoms in most with cardiovascular disease impediments to efficient diagnosis at the population level debate as to target suboptimal therapies difficulties mounting large randomized trials of sleep specific interventions and the challenging results of those few prospective cardiovascular outcome trials that have been completed and reported. Obstructive sleep apnea osa affects an estimated 15 million adult americans and is present in a large proportion of patients with hypertension and in those with other cardiovascular. Laboratory research has found that short sleep duration results in metabolic changes that may be linked to obesity.

In this paper we review 1 the pathophysiological mechanisms of osa that may causally contribute to cardiovascular disease. Obstructive sleep apnea osa is common in the general population and highly prevalent in patients with cardiovascular disease. Obstructive sleep apnea osa is associated with obesity which is also a major risk factor for heart disease and stroke.

If you suffer from undiagnosed or untreated sleep apnea the condition could take a toll on your heart health with sleep apnea the person experiences a pause in his or her breathing that can last from a few seconds to minutes during sleep often occurring five to 30 times per hour when the person starts breathing again a gasp a loud. Recognition of the high frequency of other sleep disorders occurring in patients with cardiovascular disease such as central sleep apnea csa cheyne stokes respiration csr 7 insomnia 8 and short sleep duration 9 also suggested the potential benefits of more broadly considering sleep health as fundamental to cardiovascular health 10 encouraging consideration of including sleep. Obstructive sleep apnea osa is a common medical condition that occurs in approximately 5 to 15 of the population.
