Intensive medical therapy, including aggressive control of blood pressure and cholesterol levels, for patients with asymptomatic plaque buildup in their carotid arteries (which supply blood to the brain) appears to be associated with reduced rates of cardiovascular events and reduced risk of microemboli (microscopic-sized blood clots) in the brain arteries, according to a report posted online today that will appear in the February 2010 print issue of Archives of Neurology, one of the JAMA/Archives journals. Patients with this plaque buildup, known as asymptomatic carotid stenosis, are at increased risk of heart attack, stroke and death, according to background information in the article.
A team of researchers, at Washington University School of Medicine, St Louis, has identified a group of 12 genetic variants in the HSPB7 gene that is associated with heart failure in humans. The team, led by Gerald Dorn, used an approach they have recently developed that allows ultra-high-throughput targeted DNA sequencing to identify genetic variation in four genes with biological relevance to heart failure. They identified in a large group of Caucasian individuals with heart failure, 129 separate genetic variants in the four genes, including 23 that seemed to be novel. Further analysis of 1117 Caucasian individuals with heart failure and 625 nonaffected Caucasians indicated that a block of 12 genetic variants in the HSPB7 gene was associated with heart failure.
The electrophysiology team at the Montreal Heart Institute (MHI) recently performed the first implantation of a new type of cardiac pacemaker (Accent RF™ ) in Canada. This landmark procedure was carried out on October 22, 2009 by Drs. Bernard Thibault and Peter Guerra. Both are cardiologists, electrophysiologists at the MHI and professors at the Universit√ de Montr√ al. The Accent RF™ pacemaker uses wireless technology and is intended for people with bradycardia, an abnormally slow heart rate. The patient responded favourably to the procedure, and four additional implantations have since been performed, again with successful outcomes.
Hearing a fitness professional prescribe cardio training (aerobic) for weight loss and heart health is fairly common. The suggestions usually sound like this: "Do steady pace cardio for 30 to 60 minutes three to five days every week." I want you to consider how that scientific research has shown that steady cardio is not only boring, but isn't very effective. To begin with, you need to recognize that our body is designed for bursts of energy followed by recovery, not a steady continuous exertion. Even animals cannot be observed doing endurance activity. The majority of competitive sports require bursts of energy followed by rest. To further understand the difference between endurance trainers and those who train in bursts, look at the physique of marathon runners.
We all know that life today is not as easy as it was in the past. With the advancement in technology our lifestyle has changed drastically and today we are packed with tons of things that we have to do. We have our professional work life where we have to meet with hectic schedules and deadlines and nagging bosses. At home we are stuffed with all the household work that demands more attention and concentration, so where is the time to exercise and walk? Most of the people prefer moving from one place to another in cars as it almost makes their jobs easy and they can reach their destination quickly. We eat all that junk food that accumulates a lot of fats inside us and we have no option to burn it out because we hardly have time to exercise.
Total Artificial Heart Patient Who Received Dual Transplant Celebrates 1st Christmas At Home With 2-Year-Old Son Fianc√ e
Last December, there were only two things 46-year-old Chuck Besen wanted for Christmas‚ a matching donor heart and kidney. This year, thanks to the SynCardia temporary CardioWest™ Total Artificial Heart and the dual transplant he received at University Medical Center (UMC) in March, Besen will celebrate his first Christmas at home with his 2-year-old son Dylan and his fianc√ e Jennifer Hokanson. "Today, I just thank God I'm alive, " said Besen. "The Total Artificial Heart not only saved my life, but allowed me to get strong enough to undergo my dual transplant." "It's incredible how our whole life has changed, " said Hokanson. "This whole journey has been an integral part of Dylan's life.
