Evidence is showing there are conditions that may be associated with Respiratory Sleep Disorders such as Hypertension and Heart Problems.

In its 1992 report to the US Congress, the National Commission on Sleep Disorders Research estimated that 38,000 fatal heart attacks and strokes in the United States each year are due to apnea.

Apnea causes the heart to struggle under a double burden; in addition to the autonomic problems caused by the struggle to breathe, the heart muscle itself is being starved of oxygen during an apnea.

Through monitoring of apnea, it is consistently observed that there are rises in blood pressure during each apnea event, just like the individual is lifting heavy weights. The heartbeat also invariably slows during apnea, often so much that it appears to stop.

In sufferers of Severe Obstructive Sleep Apnea  some degree of cardiovascular disease (high blood pressure, coronary artery disease, heart attack, or stroke) is almost always present.

The fact that excess weight or obesity is associated with cardiovascular disease, fatigue and general poor health as well as for sleep apnea, means that many of the health problems caused by apnea may be erroneously attributed to excess weight.


 The evidence supporting a causal role for Obstructive Sleep Apnea at night in the development of cardiovascular disease during the day continues to accumulate. This means that for anyone who has high blood pressure, heart disease or concern about a stroke, ask yourself two questions: Am I tired in the daytime? And have I been told that I snore? If the answer is yes then checking for apnea is advisable!
