Molecule that usually protects infection-fighting cells may cause plaque deposits inside arteries

A molecule that usually protects the body's infection-fighting cells might also contribute to fatty buildups that coat arteries and lead to heart disease, UT Southwestern Medical Center researchers have found. The molecule, called apoptosis inhibitor of macrophage or AIM, inhibits cell death in macrophages, which circulate in the bloodstream and help the body fend off infection and foreign...

Genetic key to growth of new arteries is identified

Researchers at the San Francisco VA Medical Center have uncovered part of the genetic mechanism that causes new arteries to grow in response to blocked arteries. The team also identified a...

Intensive statin therapy may partially reverse plaque build-up in arteries

A study presented today at the American College of Cardiology's 55th Annual Scientific Session demonstrates, for the first time, that very intensive cholesterol lowering with a statin drug can regress (partially reverse) the buildup of plaque in the coronary arteries. This finding has never before been observed in a study using statin drugs, the most commonly used cholesterol lowering tr...

Genes discovered that allow gum disease bacterium to invade arteries

Researchers have identified the genes in gum-disease bacteria that allow them to invade and infect human arterial cells, offering one possible explanation for a perceived connection between gum disease and heart disease. Scientists from the University of Florida, Gainesville, present their findings today at the 106th General Meeting of the American Society for Microbiology in Orlando, Florida.</...

Re-blockage of heart arteries prevented by vitamins

Vitamins are a bonus to everyone of us. The first ever study of the effect of B vitamins on heart disease shows a clear benefit. Angioplasty is a very widely used procedure for unblocking coronary arteries and so preventing heart attacks. It involves inserting a small balloon into the blood vessel and then inflating it to push the walls of the vessel apart. The problem is that in 20 per cent of c...

Stent shows promise in keeping arteries open

A new approach to keeping heart arteries flowing smoothly after angioplasty shows surprising success in early testing. Doctors released the longest follow-up with the new technique - the drug-coated stent. //In testing on 50 patients over 3 years, they found it to be 100 percent effective. More than 2 million Americans undergo angioplasty annually, and the new approach is likely to b...

Cholesterol Can Cause Burst Arteries

Researchers from Michigan State University had reported in the latest edition of Clinical Cardiology that cholesterol deposits could cause bursting of arterial walls that may lead to heart attacks, stroke or any number of cardiovascular diseases.// The study finds that cholesterol that has built up along the wall of an artery and crystallized from a liquid to a solid state can expand a...

Women who are obese have thicker arteries

Researchers have observed in a recent study that women who are obese in middle age have premature thickening of the carotid arteries. Recent research has marked to the carotid arteries// in the neck as a useful marker for the health of the arteries that serve the heart. If the linings of the carotid arteries are thickened, then it's more likely the person will suffer from heart disease....

Damage to arteries from injury can be avoided with carbon monoxide

Heart ailments that are treated with angioplasty or a transplantation may result in injury of the arteries. While in transplantation there is an ever-present risk of rejection of the// organ, in angioplasty, placing a balloon in the artery causes damage to the vessel walls. This in turn triggers the immune system response. A new study has however, revealed that pre-treatment with carbon monoxide...

Evidence of Nanoparticles Found in Plaque-Filled Arteries

ROCHESTER, Minn., April 30. 2007-- Scientific evidenceincreasingly links arterial calcification to the presence ofnanosized particles -- so small that some scientists questionwhether a nanoparticle can live and, if so, play a viable role incausing disease. A new Mayo Clinic study cites evidence showing the presence ofnanoparticles near plaque-filled arteries in animal models....

Calcium Plaque Build-up in the Arteries Leads to Coronary Heart Disease in Multi-Ethnic Groups

BETHESDA, Md., March 26, 2007--Having a build-up of calciumplaque in the arteries means increased risk of heart attacks anddeath from heart disease in multiple ethnic groups, according tonew findings from the Multi-Ethnic Study of Atherosclerosis (MESA)funded by the National Heart, Lung, and Blood Institute of theNational Institutes of Health. Previous studies have shown thatincreased co...
