Researchers at the Sleep and Human Health Institute and Maimonides Sleep Arts & Sciences, Ltd investigated drug failure in 1210 chronic insomnia patients and found 91% of those who completed sleep studies actually suffered from previously undiagnosed sleep apnea, a critical factor likely to be aggravating their insomnia.
Albuquerque, N.M., /2014 — Millions of people suffer from chronic insomnia. Complaining of stress, racing thoughts, and other relevant nighttime symptoms, these individuals feel incapable of sleeping all through the night. As their frustrations mount, they try drugstore or online over-the counter (OTC) remedies and many consult physicians who prescribe even stronger medications. Yet, most of these sleep aids fail to alleviate insomnia symptoms, leaving them Sleepless in “Fill-in the City.” The Sleep and Human Health Institute conducted research identifying the cause of drug failure in chronic insomniacs and found overwhelming evidence indicating that most treatment-seeking insomnia patients suffer from unrecognized sleep apnea.

“I was really, really trying — fighting to stay awake in the morning and at work,” said Pfeifle, now 74, who started the job in 2006.
He underwent a sleep study, in which he slept overnight in a sleep lab with dozens of leads that monitored his respiration, heart rhythms, leg movements, snoring and several other processes, and was diagnosed with sleep apnea.
Pfeifle’s breathing stopped over and over again while he slept when a muscle closed his throat and prevented him from inhaling oxygen and expelling carbon dioxide.
Now Pfeifle uses a CPAP machine that keeps his airway open and allows him to breathe while he sleeps.
Two new studies have shed more light on the role of continuous positive airway pressure (CPAP) on cardiovascular risk in patients with sleep apnea.
One study shows that in obese patients with moderate to severe sleep apnea, weight loss is the most important intervention and reduces inflammation, insulin resistance, dyslipidemia, and blood pressure. But CPAP had a meaningful incremental effect on blood pressure in fully adherent patients when used in addition to weight loss.
The second study provides more evidence that CPAP is effective for lowering blood pressure in patients with moderate to severe sleep apnea, even those with blood pressures in the normal range. But the study found no evidence of benefit of nocturnal oxygen supplementation on blood pressure in these patients.
Both studies are published in the June 12 issue of theNew England Journal of Medicine.
Madison, Wisconsin – Long-term compliance with continuous positive airway pressure (CPAP) therapy may help prevent hypertension and reduce the risk of cardiovascular complications in adults diagnosed with obstructive sleep apnea (OSA), according to a study from the University of Wisconsin School of Medicine and Public Health.
OSA occurs when a person’s airway collapses or is blocked during sleep, resulting in paused or shallow breathing. CPAP therapy, the most common treatment for the disorder, uses a machine to increase air pressure to stop the airway from collapsing.
Obstructive sleep apnea is strongly associated with the development of hypertension, and patients with OSA are at an increased risk of cardiovascular morbidity and mortality.
Researchers followed 47 adults (50 years or younger) with recently diagnosed obstructive sleep apnea before and after three months of continuous CPAP therapy. Subjects who had high therapy compliance (more than 4 hours of use per night) showed significant improvements in systolic and diastolic blood pressures as well as peripheral arterial tone and stiffness – key markers for cardiovascular health.
