Sleep apnea raises risk of heart failure & coronary heart disease in middle-aged and older men
Severe obstructive sleep apnea (OSA) raised the risk of heart failure for middle-aged and older men — and significantly raised the risk of coronary heart disease in men up to age 70

Metabolic disorders such as obesity and diabetes appear to share risk factors with and may influence the development of Alzheimer’s disease and other forms of dementia, according to several reports published in the March 2009 issue of Archives of Neurology, one of the JAMA/Archives journals.
Women with the cluster of cardiovascular risk factors known collectively as the metabolic syndrome appear likely to develop cognitive impairment over a four-year period. Kristine Yaffe, M.D., of the University of California, San Francisco, and the San Francisco Veterans’ Affairs Medical Center, and colleagues assessed 4,895 older women (average age 66.2) who did not have cognitive impairment at the beginning of the study.

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).

People with even minimally symptomatic obstructive sleep apnea (OSA) may be at increased risk for cardiovascular disease because of impaired endothelial function and increased arterial stiffness, according to a study in the November 2008 issue of American Journal of Respiratory and Critical Care Medicine.
Their findings suggested that minimally symptomatic OSA is a cardiovascular risk factor to a degree not previously known.

A study published in the December 24 and 31, 2008 issue of JAMA said more sleep is better for your heart and is tied to lower calcification rates in the coronary artery.
Risk factors for coronary artery calcification include heart disease risk factors such as male sex, older age, glucose intolerance, tobacco use, disorders of lipoprotein metabolism and high cholesterol levels, high blood pressure, obesity, raised inflammatory markers and a low educational level.

People with even minimally symptomatic obstructive sleep apnea (OSA) may be at increased risk for cardiovascular disease because of impaired endothelial function and increased arterial stiffness, according to a study from the Oxford Centre for Respiratory Medicine in the United Kingdom.
“It was previously known that people with OSA severe enough to affect their daytime alertness and manifest in other ways are at increased risk of cardiovascular disease, but this finding suggests that many more people — some of whom may be completely unaware that they even have OSA — are at risk than previously thought,” said lead author of the study, Malcolm Kohler, M.D.
