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 The balloon is then deflated and the catheter is withdrawn.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.

Erectile dysfunction drugs may be better than nitroglycerin in protecting the heart after a severe heart attack

During a heart attack, the heart is deprived of oxygen, which can result in significant damage to heart muscle and tissue. After the attack, most patients require treatment to reduce and repair the damage and improve their chances of survival.

People from lower socioeconomic backgrounds worse off following heart attack

People from lower socioeconomic backgrounds who suffer a heart attack come to the emergency department more often, are less likely to be treated aggressively and have higher mortality rates a year after the attack, says new University of Alberta research that has important implications for access to cardiac care.

Stents benefit people at high risk of stroke due to blocked blood vessels in the brain

For the study, researchers in Beijing evaluated 213 people who had received a stent, which is an expandable wire form used to open up a narrowing or totally obstructed blood vessel.

Drug-coated heart stents to carry a warning

An advisory panel for the Food and Drug Administration (FDA) in the U.S. has recommended that the drug-coated stents used in patients with cardiovascular disease should carry a warning.

Drug coated heart stents more likely to cause blood clots

A review and analysis of studies on drug-coated heart devices known as stents, has found that patients with them are four to five times more likely to get blood clots when compared to the older bare-metal variety.

New technology offers alternative to open heart surgery

A new method of treating mitral regurgitation (MR), the leaking of blood through the mitral valve into the heart chamber, provides a less-invasive alternative to open heart surgery.

Angioplasty no better than drugs for heart attack victims who delay treatment

In what will come as a surprise to many doctors, researchers in the United States how found that contrary to current belief, heart attack survivors with mild or no symptoms who wait three days or more to seek medical help, will achieve little benefit from the procedures used to open clogged arteries.

Faster heart attack patients treated, the better their likelihood of survival

Hospitals that provide the most rapid emergency angioplasty have specific strategies to expedite the care of patients with heart attacks, researchers at Yale School of Medicine report in the November 13 New England Journal of Medicine.

Brits to trial stem cell treatment for heart attack victims

In an experimental treatment which aims to prevent heart failure and death following a heart attack, doctors in Britain will trial a treatment which uses a patients own stem cells.

Peripheral arterial disease could predict life or death in heart patients

A growing health problem affecting older Americans puts them at higher risk for dying after heart surgery and other interventional procedures, such as heart catheterizations, according to findings published in the current edition of the Journal of the American College of Cardiology and co-authored by two leading University of Kentucky cardiologists.

Carbon monoxide shown to reverse symptoms of pulmonary hypertension

In a medical case of Jekyll and Hyde, carbon monoxide - the highly toxic gas emitted from auto exhausts and faulty heating systems - has proven effective in treating the symptoms of pulmonary arterial hypertension (PAH), an extremely debilitating condition that typically leads to right heart failure and eventual death.

High levels of two proteins in the bloodstream indicate need for action to avoid heart attack

Researchers working to decode chemical SOS signals sent out by disease-damaged hearts believe they now know better when to aggressively clear clogged arteries and when medical procedures may be unnecessary and even harmful.

Drug can quickly mobilize angiogenic cells to repair injury

To speed healing at sites of injury - such as heart muscle after a heart attack or brain tissue after a stroke - doctors would like to be able to hasten the formation of new blood vessels.

Ultrasound targets angioplasty

World Congress of Cardiology 2006 - A simple technique - combining cardiac ultrasound with a heart muscle-stimulating drug - can identify the MI patients who would benefit most from angioplasty after thrombolysis, reports a study in Hot Line session II.

First drug-eluting stent approved in Europe for most severe form of arterial disease in the leg

Cordis Endovascular, a division of Cordis Corporation, announced today that the Cypher Select Sirolimus-eluting stent received CE (Communite European) Mark in Europe for use in the treatment of severe claudication and critical limb ischemia (CLI) of infrapopliteal lesions, which is the most severe form of arterial disease in the leg.

Test on viability of heart muscle identifies patients who will benefit from angioplasty after clot-lysing therapy for an acute heart attack

Emergency angioplasty (balloondilation of the coronary vessel) is the preferred treatment for patients with an acute heart attack. Because of its limited availability worldwide, the majority of patients who are admitted to the hospital with a heart-attack are treated with clot-lysing drugs (thrombolysis).

Most effective treatments for people with coronary artery disease

Medication, angioplasty or surgery? For some heart disease patients, there's no clear-cut choice. The key to getting the best care is to follow your individual doctor's advice, new research shows.

FDA approves Plavix for STEMI heart attacks

The Food and Drug Administration (FDA) today approved the use of Plavix (clopidogrel bisulfate) for patients who have had a type of heart attack called acute ST-segment elevation myocardial infarction (STEMI), who are not going to have coronary artery repair (angioplasty).

New research may solve problem of vessels re-closing after angioplasty

Through studying pigeons with genetic heart disease, researchers at Wake Forest University School of Medicine have discovered a clue about why some patients' heart vessels are prone to close back up after angioplasty.

Is there improvement of 'vascular depression' after carotid artery stenting?

Inserting a stent to open a narrowed carotid artery has been found to reduce symptoms of depression that may be associated with carotid stenosis, according to a study in the August issue of Radiology.
