Treating Obstructive Sleep Apnea Lowers Risk of Coronary Heart Disease - CPAP Effective In Lowering Danger

Treating Obstructive Sleep Apnea Lowers Risk of Coronary Heart Disease - CPAP Effective In Lowering Danger

New research reinforces the importance of treating sleep apnea, a common breathing problem. According to researchers the risk for coronary artery disease increases up to five fold in people with obstructive sleep apnea.

There are two forms of sleep apnea. The most common form is called Obstructive Sleep Apnea (OSA). This is caused when the throat relaxes during sleep. Snoring is a common sign of sleep apnea, and for the most part, the sleeper is unaware he has the condition. When the throat momentarily closes-up the sleeper stops breathing momentarily. The symptoms include a tired feeling during the day.

Sleep Apnea – Children with untreated Severe OSA have Lower IQ

Sleep Apnea – Children with untreated Severe OSA have Lower IQ

Johns Hopkins researchers have showed children’s brains with untreated sleep apnea to damage two parts of the brain that are linked to learning abilities. The study was first published in the online August 22nd edition of the journal, Public Library of Science Medicine.

The researchers used MRI technology to look at the brain activity of 19 children that had severe obstructive sleep apnea (OSA). They also measured the brain activity of 12 children that did not have any problems with breathing while they sleep. The two locations that were measured with the MRI were the hippocampus and the right frontal cortex.

Insulin Resistance in Teens Predictor of High Blood Pressure Heart Disease

Insulin Resistance in Teens Predictor of High Blood Pressure Heart Disease

Researchers in Minnesota say that a low insulin response in the teenage years can be an early predictor of heart disease. They say the insulin resistance is independent of obesity, although obesity may increase the risk of diabetes and insulin resistance.

Dr. Sinaiko says “"The insulin clamp is considered the gold standard to measure insulin resistance, a precursor to type-2 diabetes. Insulin regulates sugars, starches, fats and proteins in the body. When cells become resistant to the effects of insulin, insulin levels increase to regulate metabolism." Sinaiko is lead author of the study and professor of pediatrics at the University of Minnesota Medical School in Minneapolis.

One Cup of Coffee Quadruples Risk of Heart Attack in Light Drinkers – People with Heart Disease More Susceptible Too

One Cup of Coffee Quadruples Risk of Heart Attack in Light Drinkers – People with Heart Disease More Susceptible Too

A cup of coffee may cause a heart attack in some people within an hour of drinking it, according to a study reported in the journal Epidemiology (“Transient Exposure to Coffee as a Trigger of a First Nonfatal Myocardial Infarction,” (Volume 17, Issue 5, September 2006.) The risk was highest among people with light or occasional coffee intake, and those with a sedentary lifestyle or other risk factors for coronary heart disease.

Sleep Apnea – Increased risk for Young Women with Asthma

Sleep Apnea – Increased risk for Young Women with Asthma

There is twice the risk to have symptoms of obstructive sleep apnea in young women suffer with asthma compared to those that don’t have asthma. Researchers from the University of Cincinnati (UC) and Cincinnati Children's Hospital Medical Center (CCHMC) first reported this study in the August edition of the journal Annals of Allergy, Asthma and Immunology.

The research team found that around 21 percent of young adult women that have asthma also routinely snored. This snoring is a symptom of obstructive sleep apnea. There has been focus on how males typically have sleep apnea, but this study points out a section of women that also are at a higher risk for developing this sleep disorder.
