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 The balloon is then deflated and the catheter is withdrawn.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.
Cristina Sabliov, LSU Biological and Agricultural Engineering professor, and Tammy Dugas, professor in the LSU School of Veterinary Medicine's Department of Comparative Biomedical Sciences, have joined forces to fight peripheral artery disease, or PAD, an ailment affecting 8 million Americans.
A removable balloon is as good as a permanent stent implant for opening small blocked arteries, according to late breaking results from the BASKET-SMALL 2 trial presented in a Hot Line Session today at ESC Congress 2018 and simultaneously published in The Lancet.
Treatments that restore blood flow to the lower limbs of people with a serious circulation condition may be cheaper and associated with longer survival, than amputation according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
Today, the U.S. Food and Drug Administration permitted marketing of two catheter-based devices designed to create a connection to veins and arteries in patients with chronic kidney disease who need hemodialysis.
The newer high-sensitivity troponin test discovers smaller amounts of heart-specific proteins, troponins, than the older troponin test and thus identifies more myocardial infarction patients than before.
Using genetic testing to inform which blood thinner to use following a procedure to open narrowed blood vessels resulted in significantly fewer complications among patients, according to new research in Circulation: Genomic and Precision Medicine, an American Heart Association journal.
The combined rate of death from any cause, heart attack or stroke within 18 months was not significantly different in patients with acute coronary syndrome who were randomly assigned to receive dual antiplatelet therapy for either six months or at least 12 months after receiving a drug-eluting stent.
Cleveland Clinic researchers found that implementing a four-step protocol for the most severe type of heart attack not only improved outcomes and reduced mortality in both men and women, but eliminated or reduced the gender disparities in care and outcomes typically seen in this type of event.
Simply changing cardiac referral processes to opt-out rather than opt-in significantly increased referral rates, according to a study presented at the American College of Cardiology's NCDR Annual Conference in Orlando.
Cardiologists at the Catharina hospital in Eindhoven have succeeded in the localized cooling of the heart during a heart attack, a world first. By cooling part of the heart prior to and following angioplasty, the cardiologists believe that the damage from a heart attack can be limited.
PLAQUETEC LTD today announced the publication of the first peer‐reviewed article demonstrating the feasibility and potential of the PlaqueTec Liquid Biopsy System™ to detect biomarkers for coronary artery disease (CAD).
A new long-term look at heart attack care and spending in America since the turn of the century shows more survival, more spending, and more variation between hospitals on both scores.
Heart attack increased the risk of vascular dementia by 35 percent, and the risk remains elevated for up to 35 years after the heart attack.
Heart failure (HF) affects approximately 5.7 million adults in the United States according to the Centers for Disease Control and Prevention. If not properly managed, HF can lead to frequent hospitalizations.
A new study conducted by researchers at the Imperial College London suggests that the placebo effect experienced by patients who receive coronary artery stents might be larger than expected, even though stents themselves are life-saving.
Percutanous angioplasty involves insertion of a stent into a blocked or narrowed coronary artery that eases the blood flow and relieves the pain of severe angina or a heart attack. It is being routinely practiced worldwide. A new study called ORBITA, has revealed that not all patients who undergo this procedure benefit from it.
A new study published in Neurosurgery finds that patients who undergo a neurosurgical procedure with surgical start times between 9 pm and 7 am are at an increased risk of developing complications compared to patients with a surgical start time earlier in the day.
Ischemia is a serious medical condition in which the flow of blood and delivery of oxygen to tissues is restricted, thus resulting in pain, weakness, and more seriously, tissue and organ damage. Ischemia in muscle tissue, most commonly as a result of atherosclerosis, leads to life-threatening diseases like coronary artery disease and stroke, but also to chronic peripheral artery disease (PAD).
Changing from scheduled appointments to an "open gym" format can reduce waiting times for cardiac rehabilitation, reports a study in the September/October issue of Journal of Cardiopulmonary Rehabilitation and Prevention.
In contrast to European and American guidelines that recommend pre-hospital antiplatelet therapy for heart attack patients suffering from ST-elevation myocardial infarction (STEMI), a new study presented at ESC Congress1 suggests this practice has no advantage over waiting for in-ho
