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 The balloon is then deflated and the catheter is withdrawn.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.
Use of a device and system to clear dislodged "debris" during percutaneous interventions to open a blocked artery following a heart attack does not appear to be clinically beneficial, according to a study in the March 2 issue of JAMA.
Cardiologists should recognize and help manage depression, stress and other common psychosocial risk factors that play a powerful role in the wellbeing and health outcomes of heart disease patients, according to an article(PDF) in the March 1, 2005 issue of the Journal of the American College of Cardiology.
A study in February’s Journal of Vascular and Interventional Radiology found that patients undergoing liver cancer treatment with Theraspheres?, radioactive microspheres containing Yittrium-90, can tolerate a 150 Gy single dose or 268 Gy repeated dose without risk of radiation-induced liver disease.
Major failings in National Health Service provision for patients recovering from heart attacks and surgery are revealed in a new report on rehabilitation services in England launched today.
Individuals with moderate to severe chest pains (angina) who have not found relief from medication may benefit from a new gene therapy approach being used by cardiologists at Rush University Medical Center to grow new blood vessels in the heart.
Routine angiography and revascularization procedures, if indicated, appear to offer better quality of life than conservative medical treatment for patients with chest pain and evidence of coronary artery disease, according to a new study (PDF file) in the Jan. 18, 2005 issue of the Journal of the American College of Cardiology.
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.
Adenosine Therapeutics announced today the award of a Phase II Small Business Innovation Research (SBIR) grant from the National Institutes of Health.
The threading of slender catheters and stents through arteries to deliver treatments to the heart, the brain and elsewhere in the body has produced nothing short of a medical revolution.
A new study led by The Cleveland Clinic shows that giving blood pressure lowering medication to heart disease patients with a “normal” blood pressure dramatically reduces risk of adverse cardiac events and slows disease progression.
In the treatment of coronary artery disease, a sirolimus drug-coated stent causes less inflammation than bare metal stents, according to preliminary research presented at the American Heart Association annual meeting by Loyola University Health System, Maywood, Ill.
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.
Many heart disease patients who are already receiving state-of-the-art therapy do not benefit from additional treatment with angiotensin converting enzyme (ACE) inhibitors, according to results of a new study funded by the National Heart, Lung, and Blood Institute (NHLBI).
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.
West Palm Beach County Court Judge Susan Lubitz ruled today that the landmark lawsuit filed by former Atkins dieter and Florida businessman Jody Gorran will go forward.
The plaintiff, 53-year-old Jody Gorran, will argue that the Atkins corporation should be held liable for the life-threatening artery blockage he suffered after more than two years on the diet. Gorran filed suit against Atkins Nutritionals on May 26 in Palm Beach County Courthouse.
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.
Authors of a research letter in this week’s issue of THE LANCET highlight how the use of drug-eluting stents (DES) may carry a risk of subsequent thrombosis if stenting is accompanied by a withdrawal of antiplatelet therapy.
In a discovery that could give physicians more control over the actions of medications, researchers at Duke University Medical Center have developed a novel drug pair – a potent anti-coagulant with a matched "antidote."
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.
