Sleep apnea is common in kidney transplant patients and it is associated with an increased risk of high blood pressure, heart disease, and stroke, according to a study published in the Clinical Journal of the American Society Nephrology.
Cardiovascular disease is the most common cause of death in individuals who receive kidney transplants, and doctors monitor transplant recipients for high blood pressure, or hypertension, and other signs of heart trouble, according to the study.

More than 12 million people in the U.S. suffer from sleep apnea, most common among the overweight and obese. More than just loud snoring, it can lead to high blood pressure, stroke, cardiovascular disease, and a poor quality of life. For years, doctors have told patients with sleep apnea that their best bet for alleviating it would be to lose weight, but there’s been very little research-based evidence to prove that.

Moderate to severe obstructive sleep apnea is associated with an increased risk of death from any cause in middle-aged adults, especially men, according to new results from a landmark study supported by the National Heart, Lung, and Blood Institute of the National Institutes of Health.

Clinicians should be alert to patients reporting excessive daytime sleepiness, or EDS, says the European Society of Cardiology, after a study found healthy elderly people who regularly report feeling sleepy during the day have a significantly higher risk of dying from cardiovascular disease.
The Three City study, published in Stroke, by the American Heart Association, found elderly people who reported excessive daytime sleepiness have a 49 percent relative risk increase of cardiovascular death from cerebrovascular disease, myocardial infarction, and heart failure, compared to those who do not report problem sleepiness during waking hours.

You may never hear fruit flies snore, but rest assured that when you’re asleep they are too. According to research published in a professional journal, scientists have shown that the circadian rhythms (sleep/wake cycles) of fruit flies and vertebrates are regulated by some of the same “cellular machinery” as that of humans.
The study is significant because the sleep-regulating enzyme analyzed in this research is one of only a few possible drug targets for circadian problems that can lead to seasonal affective disorder (SAD), insomnia, and possibly some cancers.

Sleeping less than seven-and-a-half hours per day may be associated with future risk of heart disease, according to a report in the November 10, 2008, issue of Archives of Internal Medicine, one of the JAMA/Archives journals. In addition, a combination of little sleep and overnight elevated blood pressure appears to be associated with an increased risk of the disease.
“Reflecting changing lifestyles, people are sleeping less in modern societies,” according to background information in the article. Getting adequate sleep is essential to preventing health conditions such as obesity and diabetes as well as several risk factors for cardiovascular disease including sleep-disordered breathing and night-time hypertension (high blood pressure).

If a good night’s sleep helps the brain and body perform better, it’s a good guess that sleep problems can cause more than just fatigue. Numerous studies have shown a connection between sleep disorders and medical conditions such as cardiovascular disease, cerebrovascular disease, and metabolic disorders, including the risk of obesity and diabetes mellitus.
In the November issue of Mayo Clinic Proceedings, Mayo Clinic researchers outline several interesting associations between sleep disorders and eye disease.

Loss of sleep, even for a few short hours during the night, can prompt one’s immune system to turn against healthy tissue and organs.
A new article in the September 15, 2008 issue of Biological Psychiatry, by the UCLA Cousins Center research team, reports that losing sleep for even part of one night can trigger the key cellular pathway that produces tissue-damaging inflammation. The findings suggest a good night’s sleep can ease the risk of both heart disease and autoimmune disorders such as rheumatoid arthritis.
