In Switzerland, more than 20,000 people (37% of all deaths) die of cardiovascular disease caused by atherosclerosis each year. Treatment options are currently available to people who suffer from the disease but no drug can target solely the diseased areas, often leading to generalized side effects. Intravenous injection of a vasodilator (a substance that dilates blood vessels), such as nitroglycerin, dilates both the diseased vessels and the rest of our arteries. Blood pressure can thus drop,...

In human coronary arteries, atherosclerotic plaques tend to spread downstream because of the changes in blood flow patterns the plaque causes, researchers have found. This insight comes from a study of fluid dynamics in the arteries of people being treated for coronary artery disease. The results are being presented Tuesday, Nov. 15 at the American Heart Association Scientific Sessions meeting in Orlando. The study leader is Habib Samady, MD, professor of medicine and director of...

New method could sensitively detect pre-atherosclerotic regions that otherwise showed no clinical signs of atherosclerosis A new study published in the Annals of Biomedical Engineering shows that a MEMS thermal sensor deployed by an angiogram catheter can detect the earliest stages of atherosclerosis. The MEMS thermal sensor used convective heat transfer to detect pre-atherosclerotic regions of arteries that otherwise showed no clinical signs of atherosclerosis. Although diet and lifestyle...

(Ivanhoe Newswire) -- New research proves it: testing for blocked neck arteries only necessary for people with stroke risk factors, according to newly released guidelines. Experts agree there isn't sufficient evidence of benefit for widespread screening. "However, if your doctor hears abnormal blood flow when listening to your neck arteries, or if you have two or more risk factors for stroke (such as high cholesterol or a family history), then it is a reasonable approach," Jonathan L....

Mayo Clinic researchers found that healthy young people who put on as little as 9 pounds of fat, specifically in the abdomen, are at risk for developing endothelial cell dysfunction. Endothelial cells line the blood vessels and control the ability of the vessels to expand and contract. "Endothelial dysfunction has long been associated with an increased risk for coronary artery disease and cardiovascular events," says Virend Somers, M.D., Ph.D., a cardiologist at Mayo Clinic. "Gaining a few...

A new animal model of atherosclerosis has allowed researchers to identify a host of genes turned on or off during the initial stages of the process, before a plaque appears in the affected blood vessel. The results were published June 15 in Blood, the journal of the American Society of Hematology. The model is the first to definitively show that disturbances in the patterns of blood flow in an artery determine where atherosclerosis will later appear, says senior author Hanjoong Jo, PhD, Ada...

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...

It is second nature for most of us that exercise protects against heart attack and stroke, but researchers have spent 30 years unraveling the biochemistry behind the idea. One answer first offered by researchers at the University of Rochester Medical Center is that athletic hearts push blood through arteries with greater force, which alone triggers reactions that protect against dangerous clogs in blood vessels. In the latest study out of Rochester, published recently in the journal Blood,...
