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 The balloon is then deflated and the catheter is withdrawn.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.
Scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have discovered a new mechanism of action of metoprolol, a drug that can reduce the damage produced during a heart attack if administered early.
While heart disease remains the leading cause of death for both men and women in the U.S., according to the Centers for Disease Control, advances in medicine over the past 40 years have led to a substantial reduction in cardiovascular-related deaths.
Deep vein thrombosis (DVT) is a serious condition that occurs when a blood clot forms in a vein, often in the deep veins of the legs, thigh or pelvis. Those clots can break loose, travel to the lungs and block blood flow, causing a pulmonary embolism.
A new tool for assessing the narrowing of the heart's arteries was found to be as effective as current methods and less painful for patients.
Physician researchers at Thomas Jefferson University suspect that some cases of coronary artery spasm go unrecognized and are incorrectly treated with stents.
Patients experiencing a major heart attack often have more than one clogged artery, but under current guidelines doctors typically only clear the blockage responsible for the heart attack.
For patients experiencing angina (chest pain) or a heart attack, a new tool called instantaneous wave-free ratio (iFR) was equivalent to the currently-preferred tool, fractional flow reserve (FFR), in terms of incidence of major adverse events according to two studies presented at the American College of Cardiology's 66th Annual Scientific Session. The studies also showed iFR resulted in markedly less patient discomfort and reduced procedure-related adverse events compared to FFR.
Common impotence drugs such as Viagra may have a life-prolonging effect on patients who have suffered a myocardial infarction, a paper published by researchers at Karolinska Institutet suggests.
Hospitals can improve patient care and reduce costs associated with coronary angioplasty if cardiologists perform more of these procedures through an artery in the wrist and if they take steps to discharge such patients on the same day, according to a new study led by Washington University School of Medicine in St. Louis.
If hospitals can perform more transradial, same-day percutaneous coronary intervention, or PCIs, not only will patients benefit because it is associated with have less complications, but collectively, hospitals across the U.S. could save $300 million each year, according to research published today in JACC: Cardiovascular Interventions.
Over 93 percent of heart attack patients are receiving stents within the guideline-recommended threshold of 90 minutes after arriving at the hospital, with the median time to stenting only 59 minutes, according to a broad report on trends in heart disease care from the American College of Cardiology's National Cardiovascular Data Registry published in the Journal of the American College of Cardiology.
A physician at Scripps Health's Prebys Cardiovascular Institute has become the first in the Western United States to treat heart attack patients with a new supersaturated oxygen (SSO2) system in an attempt to reduce permanent damage to their heart muscle.
The inability of cells to eliminate damaged proteins and organelles following the blockage of a coronary artery and its subsequent re-opening with angioplasty or medications - a sequence known as ischemia/reperfusion - often results in irreparable damage to the heart muscle.
New guidelines for the treatment of peripheral artery disease (PAD), include recommendations on the use of antiplatelet therapy to reduce the risk of blood clots and statin drugs to lower cholesterol and advise PAD patients to participate in a structured exercise program.
UCLA researchers have found that undergoing a computer tomographic angiography was a better motivator to get people with suspected coronary artery disease to adopt healthier lifestyle practices than an exercise electrocardiography and stress test.
The American College of Cardiology's National Cardiovascular Data Registry was the source of data for research published throughout 2016, including a study examining if atrial fibrillation patients are being prescribed oral anticoagulants, how appropriate use criteria correlates to angioplasty rates and the variation among racial groups for revascularization procedures.
Magnetic resonance imaging (MRI) uses a strong magnetic field to image the body and is known as the gold standard in diagnostic imaging.
Drug-eluting stents had a clear advantage over bare metal stents in patients undergoing revascularisation of saphenous (leg) vein grafts, results of the BASKET-SAVAGE trial show.
An invasive imaging technique called optical coherence tomography (OCT) can visualize the coronary arteries in patients undergoing percutaneous coronary intervention (PCI) and lead to better outcomes compared to standard angiography-guided PCI, according to new findings reported here.
Direct catheter-based thrombectomy is equally effective to bridging thrombolysis in the treatment of acute ischaemic stroke, according to results from the observational PRAGUE-16 registry study presented at ESC Congress 2016 today.
