Angioplasty News and Research

RSS

In angioplasty procedures, a balloon is fed through a catheter and used to prop open an artery that has become narrowed or blocked. In cases where stenting is appropriate, a stent mounted on a balloon is inserted and inflation of the balloon expands the stent against the blocked artery wall to hold the vessel open. The balloon is then deflated and the catheter is withdrawn. Stent treatment of arteries holds them open and improves blood flow to the heart. In cases where post-dilatation is needed, a high-pressure balloon is inflated inside a stent to help better place the stent against the vessel wall.

Australian researchers discover a 'novel molecular dictator with a conscience'

University of New South Wales (UNSW) researchers have uncovered an important naturally occurring mechanism in the body where "bad" cells that cause blockages in our blood vessels are kept under strict growth control, while "good" cells that keep our blood vessels free of clots and growths are left unaffected.

Emergency angioplasty use rises, but some patients still miss out

Compared with their counterparts a decade ago, today's heart attack patients are receiving emergency angioplasty or clot-busting drugs to re-open clogged arteries at a far greater rate, but 10 percent of patients who could benefit from this life-saving treatment still do not receive it, according to a study published in The American Journal of Medicine by Yale and University of Michigan researchers.

Genetically engineered herpes simplex virus keeps arteries free-flowing

A genetically engineered herpes simplex virus, primarily known for causing cold sores, may help keep arteries "free-flowing" in the weeks following angioplasty or stent placement for patients, according to research published early in the online edition of PNAS (Proceedings of the National Academy of Sciences of the United States of America).

Transplant of angina patients' purified stem cells provides symptom relief

The first U.S. study to transplant a potent form of purified adult stem cells into the heart muscle of patients with severe angina provided evidence that the procedure is safe and produced a reduction in angina pain as well as improved functioning in patients' daily lives, reports the lead researcher at Northwestern University's Feinberg School of Medicine.

Black Medicare patients less likely to receive angioplasty following a heart attack

A large study has found that black Medicare patients are less likely than white patients to receive blood vessel opening procedures such as angioplasty following a heart attack, whether they are admitted to hospitals that provide or do not provide these procedures, but also experience higher mortality rates at 1 year, according to a study in the June 13 issue of JAMA: The Journal of the American Medical Association.
