Latest Artery Stories

Scientific collaborators from Yale School of Medicine and University College London (UCL) have uncovered the molecular pathway by which new arteries may form after heart attacks, strokes and other acute illnesses bypassing arteries that are blocked. Their study appears in the April 29 issue of Developmental Cell. Arteries form in utero and during development, but can also form in adults when organs become deprived of oxygen — for example, after a heart attack. The organs release a...

Long term exposure to air pollution may be linked to heart attacks and strokes by speeding up atherosclerosis, or "hardening of the arteries", according to a study by U.S. researchers published in this week's PLOS Medicine. The researchers, led by Sara Adar, John Searle Assistant Professor of Epidemiology, University of Michigan School of Public Health, and Joel Kaufman, Professor of Environmental and Occupational Health Sciences and Medicine, University of Washington, found that higher...

Washington University in St. Louis [ Watch The Video Red Blood Cells Bifuracating in Capillary ] In an engineering breakthrough, a Washington University in St. Louis biomedical researcher has discovered a way to use light and color to measure oxygen in individual red blood cells in real time. The technology, developed by Lihong Wang, PhD, the Gene K. Beare Distinguished Professor of Biomedical Engineering, could eventually be used to determine how oxygen is delivered to normal and...

Lawrence LeBlond for redOrbit.com - Your Universe Online Modern lifestyle factors – those that include smoking, eating fatty foods and lack of exercise – have been associated with unhealthy hearts for decades. But a new study in The Lancet suggests this decades-old health issue is in fact much older – at least 4,000 years older. The evidence comes from CT scans of ancient mummies, where researchers found calcification in their arteries, which suggests hardening of the arteries...

University of Illinois at Urbana-Champaign A 98-year-old researcher argues that, contrary to decades of clinical assumptions and advice to patients, dietary cholesterol is good for your heart – unless that cholesterol is unnaturally oxidized (by frying foods in reused oil, eating lots of polyunsaturated fats, or smoking). The researcher, Fred Kummerow, an emeritus professor of comparative biosciences at the University of Illinois, has spent more than six decades studying the dietary...

Muscle cells on outside of blood vessels wrongly accused for instigating lung disease It turns out the muscle cells on the outside of blood vessels have been wrongly accused for instigating lung disease. New research shows that while these muscle cells are responsible for constricting or dilating the blood vessels, they are not responsible for sensing the amount of oxygen that gets to the lungs. That message comes from the endothelial cells – special cells that line the blood vessels –...

By: Katie Williams, Ivanhoe Health Correspondent (Ivanhoe Newswire) – Millions of patients affected by cardiovascular disease need small-diameter blood vessel grafts to help route their blood around blocked arteries. Now, researchers have created a new way to grow healthy, new small-diameter blood vessels from adult stem cells extracted during liposuction. These blood vessels are grown in a lab and could solve large problems associated with grafting blood vessels elsewhere in the...
