Statistics - Listing the Needs

The National Sleep Foundation (NSF) statistics reveal that approximately 40 million people suffer from chronic sleep disorders.It is estimated that 85 to 90% of these individuals remain undiagnosed, representing a large untapped market.

In 2008, the Obstructive Sleep Apnea therapy device and sleep diagnostic system markets were the fastest growing segments in healthcare. This was due to the rising prevalence of sleep disorders, as well as the increased awareness of the diagnosis and treatment of these conditions.

Conditions

Heart failure – 5 Million Americans

• 400,000 new cases diagnosed each year (1,100/day)
• 68% of patients with CHF also have Obstructive Sleep Apnea
• The Sleep Heart Health study demonstrated that the presence of Obstructive Sleep Apnea increased the odds ratio of heart failure by 2.38 times
• Accumulation of edema in the neck and upper airway may predispose Heart Failure patients to upper airway collapse
• CHF Patients that have Obstructive Sleep Apnea have a 56% 3yr mortality rate vs. 11% on patients without Obstructive Sleep Apnea.

Hypertension – 44.7 Million Americans

• Hypertensive heart disease is the fastest growing health problem in the U.S.
• 40% of patients with hypertension also have Obstructive Sleep Apnea (Sin et al, 2001)
• Clinical hypertension is under-diagnosed in at least 40% of cases of newly diagnosed sleep apnea patients (Baguet et al, J Hypertension 2005)
• Patients with an AHI 5-15 have a 200% increased chance for developing hypertension. Patients with an AHI >15 have a 300% chance (Peppard, 2000)

Endocrinology Consequences

• Diabetes – 21 Million Americans
• 50% of patients with Type II Diabetes have Obstructive Sleep Apnea.
• There has been a 76% increase in Type II diabetes in adults 30-40 yrs old since 1990
• Obstructive Sleep Apnea is independently associated with incidence of Type II Diabetes, an increasing severity of Obstructive Sleep Apnea is associated with increased risk of developing Type II Diabetes. (Botros, 2007)
• Obese patients with Obstructive Sleep Apnea are more insulin resistant than patients with simple obesity. (Lanfranco, Pivetti, 2003)
• SDB is found in 40 to 60% of insulin resistant diabetic patients thus it is a prevalent condition associated with glucose intolerance and insulin resistance. (Sorkin, 2002)
