CINCINNATI, Nov. 16, 2010 /PRNewswire-USNewswire/ -- One of the leading risk factors for heart attack and stroke is being linked with arterial stiffness - not only in adults but also in children, according to a new Cincinnati Children's Hospital Medical Center study. The study shows that arterial stiffness in youth is associated with increased mass of the left ventricle - the pumping chamber of the heart. This LVM, in turn, raises the risk for heart attack and stroke. The study comes...

SAN DIEGO, Aug. 25 /PRNewswire/ -- Brahm Brahm today published detailed instructions and templates for analyzing blood pressure curves into arterial smooth muscle, elastic, and collagen components. For the first time, researchers have tools to quantify the participation of smooth muscle, elastic, and collagen in the generation of blood pressure, high blood pressure, and arterial stiffness. Article 2 of the Musculoelastic series is available at http://www.musculoelasticmodel.com...

EPFL Laboratory of Multiscale Modeling of Materials, in Switzerland, has developed a flowing 3D model of the cardiovascular system that should allow for predictions of certain heart diseases before they become dangerous. The supercomputer Cadmos, installed at the Ecole Polytechnique F©d©rale de Lausanne (EPFL) in August of 2009, has bared one of its first fruits: the Laboratory of Multiscale Modeling of Materials has recently developed a computer program the accurately models the...

STANFORD, Calif. "” Scientists at the Stanford University School of Medicine studying cardiac development in mouse embryos have identified the source of cells that become the coronary arteries "” the vessels that deliver blood to nourish the continuously pumping heart muscle. Surprisingly, the cells originate in an entirely different part of the heart than previously thought. Although they begin life as venous cells, directing blood into the chambers of the embryonic heart, they...

U.S. medical researchers have discovered a grid of small arteries at the surface of the brain redirects and controls blood flow following a stroke. University of California-San Diego scientists say they found the mesh-like network adjusts to restore normal supply when blood slows after a stroke. This is optimistic news, said Professor David Kleinfeld, whose team studies blood flow in animal models of stroke. Damage from stroke can continue for hours or even days as compromised brain tissue...

Even occasional cigarette smoking can impair the functioning of your arteries, University of Georgia researchers said. Study co-author Kevin McCully said that researchers used ultrasound to measure how the arteries of young, healthy adults respond to changes in blood flow. Previous studies have shown reductions in the arterial health of people who smoke regularly, McCully said, but what's surprising about this study is that the study subjects were occasional smokers -- less than a pack a...

Even occasional cigarette smoking can impair the functioning of your arteries, according to a new University of Georgia study that used ultrasound to measure how the arteries of young, healthy adults respond to changes in blood flow. "Most people know that if they have a cigarette or two over the weekend that it's not good for their arteries," said study co-author Kevin McCully, a professor of kinesiology in the UGA College of Education, "but what they may not be aware of"”and what our...

By Dr Donohue Q: My husband, 68, has just been told he has hypertrophic cardiomyopathy. His cardiologist suggests treatment with alcohol ablation. I know this is fairly new, and I wonder how safe it is and if the results are worth the risks. He has tried medicine, but the condition has gotten worse. What can you tell us about this procedure? A: "Cardiomyopathy" indicates that the heart trouble lies in the heart muscle, not the arteries that bring blood to the heart (the most common kind...

DEAR DR. DONOHUE: I had a triple coronary artery bypass in April 1998. The vessel used for the grafts was taken from my leg. A cardiologist tells me that the leg vessel graft needs replacement in eight years. It is not as good as grafts taken from arteries in the arm or the chest wall. I feel fine. It has been 10 years since my operation. Am I living on borrowed time? Why isn't the leg vessel as good as the others? - W.P. ANSWER: Hold on a minute. Predictions about the longevity of grafts...

A Greek study said green tea appears to have a short-term beneficial effect on the large arteries of the heart. The study by Dr. Nikolaos Alexopoulos and colleagues in the cardiology department of Athens Medical School found that green tea rapidly improves the function of endothelial cells lining the circulatory system, reducing the progression of atherosclerosis. The study suggests endothelium-dependent brachial artery dilatation increased significantly after drinking green tea, with a...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
