Balloon Angioplasty is a procedure to enlarge the opening in a blood vessel that has become narrowed or blocked by plaque (a buildup of fat and cholesterol on the inner wall of the blood vessel). A small balloon is filled with air inside the blood vessel to push the plaque against the blood vessel wall and increase the opening.
Using positron emission tomography (PET) scanning rather than other types of imaging as the first tool to diagnose heart-vessel blockages is more accurate, less invasive and saves dollars, a study by a University at Buffalo team has shown.
A blood test in combination with a stress test can help better determine if someone is likely to have a blocked heart artery, according to a study by doctors at Providence Hospital in Southfield, Mich.
The death rate during combination surgery to bypass clogged coronary arteries and simultaneously replace a heart valve in very sick patients can be as high as one in five, but a review of records of very sick patients who underwent balloon angioplasty, followed by heart valve replacement surgery, found only one death among 26 patients.
The magnetic-assisted intervention is being introduced in the United States and Europe, with fewer than 15 systems installed at institutions worldwide. Developed by Stereotaxis, Inc., a St. Louis firm, the system was approved by the U.S. Food and Drug Administration in 2003.
While the placement of stents in newly reopened coronary arteries has been shown to reduce the need for repeat angioplasty procedures, researchers from the Duke Clinical Research Institute have found that stents have no impact on mortality over the long term.
Rosiglitazone, a drug taken to help improve blood sugar levels, also helps boost the effectiveness of a treatment for opening clogged arteries, according to a study in the November issue of Diabetes Care.
A biomarker called cystatin C, which measures kidney function, predicts which people are less likely to survive a heart attack, according to research published in Circulation: Journal of the American Heart Association.
New German research from Heidelberg University suggests that moderate drinking cuts the rate of further narrowing after surgery to open blocked arteries. The findings are published in the current issue of Heart.
A pooled analysis of 11 previously published trials provides evidence that drug-eluting stents (DES)—increasingly used in coronary angioplasty—have benefits over bare-metal stents (BMS) by reducing the need for later revascularisation and reducing the risk of cardiac events
Myogen has announced that the United States Food and Drug Administration has granted orphan drug designation to ambrisentan for the treatment of pulmonary arterial hypertension (PAH).
Early intervention with a novel kind of "smart gene therapy" might effectively prevent the organ damage commonly suffered by heart attack victims, suggests a new animal study by researchers at Brigham and Women's Hospital in Boston and Duke University Medical Center.
Results of a randomised trial in this week’s issue of THE LANCET suggest that the transfer of adult stem cells derived from bone marrow could improve cardiac functioning after heart attack.
Repeating balloon angioplasty and/or stenting procedures to open narrowed arteries in elderly patients may add more than $700 million a year to Medicare expenses, according to a report in today’s rapid access issue of Circulation: Journal of the American Heart Association.
An investigation of how blood flows through stents after opening clogged arteries has led a team of researchers at the Medical College of Wisconsin Cardiovascular Center in Milwaukee to suggest that stents designed with thinner and fewer linkages may be the basis of a new generation of stents.
Branch points in the arteries are a common area of atherosclerotic disease, resulting in the occlusion of both branches. These branch points can generally be defined as a main branch and a side branch, and, in treating the disease, the question of what is the optimal course of action, opening the main branch, the side branch, or both, remains uncertain.
A new stent appears safe and effective for preventing arteries from reclosing in coronary heart disease patients, based on one-year results of the first human trial using this stent reported in today’s rapid access issue of Circulation: Journal of the American Heart Association.
Bypass surgery results in better five-year survival than balloon angioplasty and stent procedures for patients with serious coronary artery disease and additional health conditions such as diabetes
