- Obstructive sleep apnea is associated with cardiovascular morbidity and mortality, particularly heart failure, a study found.
- The severity of obstructive sleep apnea was significantly associated with higher levels of high-sensitivity troponin, suggesting that subclinical myocardial injury may play a role in the association with risk of heart failure.
After adjustment for other risk factors, each 10% decrease in the lowest nocturnal oxygen saturation among adults undergoing a first-time polysomnogram for suspected sleep-disordered breathing was associated with a 14% greater risk of sudden cardiac death or resuscitated cardiac arrest (HR 1.14, 95% CI 1.01 to 1.27), according to Virend Somers, MD, PhD, of the Mayo Clinic in Rochester, Minn., and colleagues.
Sleep factors associated with a significantly greater likelihood of remaining free from sudden cardiac death or resuscitated cardiac arrest included an apnea-hypopnea index of less than 20 events per hour (HR 1.60, 95% CI 1.14-2.24), a mean nocturnal oxygen saturation of 93% or higher (HR 2.93, 95% CI 1.98-4.33), and a lowest nocturnal oxygen saturation of 78% or higher (HR 1.81, 95% CI 1.28-2.56), the researchers reported online in the Journal of the American College of Cardiology.
Yes. CPAP compliance matters.
People with obstructive sleep apnea (OSA) have subclinical arterial disease on par with that seen in patients with diabetes, researchers found.
Patients with moderate to severe obstructive sleep apnea have endothelial dysfunction and arterial stiffness, similar to patients with diabetes mellitus.
Small study with some interesting findings.
Sleeping too little or too much, abnormal breathing during sleep, and excessive daytime sleepiness all were significantly associated with cognitive impairment — years later in some cases.
Conclusions: Sleep apnea is common in patients with CKD and increases as kidney function declines. Almost 50% of patients with CKD and ESRD experience nocturnal hypoxia, which may contribute to loss of kidney function and increased cardiovascular risk.
Conclusions: Primary care providers under diagnose OSA in patients with T2DM.
Up to 90% of patients with type 2 diabetes mellitus (T2DM) have obstructive sleep apnea (OSA).
Think about that.
Conclusion: Severe OSA is associated with cardiovascular death in women, and adequate CPAP treatment may reduce this risk.
Hey, it’s only the cerebral cortex where your information processing occurs.
It’s only your CPU that loses gray matter.
Small sample, just 36 men. Yeah, go ahead and skip the CPAP tonight.
A new study confirms that stroke patients who have moderate to severe obstructive sleep apnea (OSA) have a higher mortality risk than those without this condition and suggests that the successful use of continuous positive airway pressure (CPAP) therapy can reduce this excess risk.
