Wrong Dosage of Blood Thinning Medication given to 75 Percent of Patients

Prescription bottle - BSN

(Best Syndication News) - Researchers at the Intermountain Medical Center Heart Institute found that 75 percent of the patients taking blood thinners were not given the correct dosage. The study investigated 521 patients taking clopidogrel (Plavix) and prasugrel (Effient) and found that many had dosage amounts that were not effective. The study results were presented today at the American Heart Association Scientific Sessions 2012 in Los Angeles.

The wrong dosage could be serious either way. Too much medication could cause uncontrolled bleeding, while too little medication puts the patient at an increased risk for developing blood clots. Blood thinning medication is often used as a way to prevent blood clots from forming. These clots can cause strokes and heart attacks.

Pacemakers could be powered by Heartbeat

(Best Syndication News) - Researchers created an experimental device that could collect energy from heartbeats to help power pacemakers. The early study suggests that the technology holds promise and can improve the way pacemakers work. The study was presented at the American Heart Association's Scientific Sessions 2012.

Pacemakers, and possibly other devices such as implantable defibrillators, could take advantage of piezoelectricity technology as a power source. The energy charge is created from motion.

The findings suggest that patients could power their pacemakers — eliminating the need for replacements when batteries are spent. M. Amin Karami, Ph.D., lead author of the study and research fellow in the Department of Aerospace Engineering at the University of Michigan in Ann Arbor, said that these implantable devices require very little power to work.

Hereditary High Blood Cholesterol not Identified and Treated Effectively

(Best Syndication News) - A research study from the University of Copenhagen and Herleve Hospital found that more Danes than previously thought have hereditary high blood cholesterol, and the condition is not being treated optimally. The study results were published in The Journal of Clinical Endocrinology & Metabolism.

Dr Børge Nordestgaard, clinical professor at the Faculty of Health and Medical Sciences and senior physician at Herlev Hospital, said of the 69,000 Danes investigated, they found that 1 out of 137 people in Denmark had hereditary high blood cholesterol.

Water Aerobics just as good as other Cardio Workouts

(Best Syndication News) - Exercising in the water has just as much aerobic benefit as working-out on land, suggests a new study. The researchers found pedaling an exercise bike in a swimming pool had a similar aerobic effect to a typical stationary bike workout. The study was presented today at the Canadian Cardiovascular Congress.

The immersible ergocycle, which is a stationary exercise bike that can be put in a swimming pool, was studied. Many people might assume that moving in water is not as difficult as moving on land. The researchers compared land and water bicycling workouts for effectiveness.

Healthy participants perform exercise tests in the water and on land. The water level was up to their chest level. The intensity of the workout was increased every minute until the riders were exhausted. The researchers found that the land-workout was almost the same when they compared the maximal oxygen consumption rates.

Resveratrol Supplements did not benefit Healthy Women

Drink - BSN

(Best Syndication News) - A study on healthy middle-aged women found no benefit gained by taking resveratrol supplements, a compound found in red wine. The study was reported in the October 25 online edition of Cell Metabolism.

Previous research had suggested that resveratrol in red wine could help reduce heart disease risk and increase lifespan. People have been taking resveratrol in hopes of better health. The U.S. resveratrol supplement business has grown into a $30 million a year industry. People take supplements because they would have to drink large amounts of red wine to gain the benefit – at least that was the conventional wisdom. Researchers from Washington University School of Medicine in St. Louis wanted to see if taking resveratrol supplements was beneficial to otherwise healthy women.
