Apnea is a condition where the patient stops breathing during sleep and
can be treated by use of a CPAP or BiPAP. In theory, CPAP/BiPAP
should take care of the situation. But for a number of real world
practical reasons often it does not and many users stop use or use
infrequently increasing their risk of a fatal heart attack..
In a study by the University of Wisconsin and Boston University School
of Medicine published in the American Journal of Respiratory and
Critical Care Medicine Vol. 165. pp. 1217-1239, (2002) the authors
concluded that even mild obstructive sleep apnea is associated with
significant morbidity. Evidence from the studies indicates that
undiagnosed (untreated) obstructive sleep apnea, with or without
symptoms, is independently associated with increased likelihood of
hypertension, cardiovascular disease, stroke, daytime sleepiness, motor
vehicle accidents, and diminished quality of life.
Yale University reported in the Science Daily in May 2007, on a study
of 1,132 patients referred for sleep apnea evaluation. The study
showed that sleep apnea, if not treated, over a period of four or five
years increases the risk of a heart attack or death by 30
Researchers at the Mayo Clinic found that individuals with untreated
sleep apnea have an increased risk of having a heart attack during the
time they sleep (12am to 6 am). The July 2008 issue of the
Journal of the American College of Cardiology reports that most heart
attacks occur between 6am and noon. The study evaluated 92 patients
admitted because of a heart attack. Of those with a heart attack
between 12am and 6am 91% had sleep apnea. This important finding
speaks for itself.
The author was diagnosed with sleep apnea in November 1999 and has used
BiPAP continuously since. He is a pharmacist, has a PhD in
biochemistry and is an attorney practicing chemical/medical patent
law. With his medical-research-invention background he has
modified use of the CPAP/BiPAP system, added features and provides many
helpful hints he learned by experience over the past decade which makes
daily use of CPAP much easier.
