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 The balloon is then deflated and the catheter is withdrawn.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.
The most common type of heart disease -- coronary artery disease -- affects 6.7% of adults and accounts for 20% of 2 in 10 deaths of adults under age 65.
Democratic state attorneys general are asking the Supreme Court to intervene this term in a case that could invalidate the entire Affordable Care Act.
Most patients do not understand or recall information given to them before heart procedures. For example, many patients mistakenly believe that opening blocked arteries will cure them of heart disease.
A Yale-led group of doctors has developed a new mathematical model that can predict the risk of acute kidney injury (AKI) in patients undergoing a common heart procedure.
Devices coated with a drug called paclitaxel that are used for widening blocked arteries in legs and feet are safe and not linked to an increase in deaths, according to a study of nearly 65,000 patients, published in the European Heart Journal today (Wednesday).
New data from the IDEAL-LM trial found that a biodegradable polymer everolimus-eluting stent (BP-EES) followed by four months of dual antiplatelet therapy (DAPT) was safe and effective compared to a conventional durable polymer everolimus-eluting stent (DP-EES) followed by 12 months of DAPT in patients undergoing PCI for unprotected left main coronary artery (uLMCA) disease.
A new shock classification scheme released by the Society for Cardiovascular Angiography and Interventions and endorsed by the American College of Cardiology, American Heart Association, the Society of Critical Care Medicine and the Society of Thoracic Surgeons was recently applied in a retrospective study analyzing patients in the cardiac intensive care unit at the Mayo Clinic.
A new study of New York City firefighters has found that exposure to 9/11 World Trade Center dust is associated with a significantly increased long-term risk of cardiovascular disease.
Early use of an implantable cardioverter-defibrillator after primary coronary intervention lengthens survival in patients at high risk of death after ST-segment elevation myocardial infarction.
A study revealed at the ESC Congress 2019 held in Paris last weekend reveals that abnormal microbe population in the body may lead to impairment of the stable coronary plaques and lead them to be dislodged leading to a heart attack. The abstract titled, “A different microbial signature in plaque and gut of patients presenting with ACS: a possible role for coronary instability” was presented on the 31st of August 2019.
Heart muscle can continue to die even after restoring blood following a heart attack, and scientists have new evidence that one way to help it live is by boosting levels of a tiny RNA that helped the heart form.
The annual average PM10 concentration was significantly higher in polluted cities (50.95 μg/m3) compared to unpolluted cities (26.62 μg/m3). In both polluted and unpolluted areas, a rise in PM10 concentration was significantly associated with a greater frequency of PCI.
Patients appear to be at higher risk of heart problems or stroke when prescriptions for the newest cholesterol-lowering drugs are rejected by insurance companies or unfilled by patients, according to new research in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.
There was no time to spare when air passenger Hutz Hertzberg, DMin, PhD, suddenly collapsed at Midway Airport in full cardiac arrest.
Researchers from Joslin Diabetes Center, using a genome-wide association study, have identified a genetic factor linked to the development of diabetic peripheral neuropathy.
Atherosclerosis is a common, potentially serious condition caused by a build-up of fatty material in the lining of the artery walls. It can lead to coronary artery disease, stroke or kidney problems, and existing treatments tend to be only short-term fixes.
Prediabetes, the precursor stage before type 2 diabetes, does not increase the cardiac risk of patients with coronary artery disease.
Drug-coated balloon catheters to open narrowed blood vessels and to deliver drugs to the impacted sites are used frequently for the treatment of peripheral arterial disease.
Coronary artery bypass grafting surgery may be the best treatment option for most patients with more than one blocked heart artery, according to research published today in The Annals of Thoracic Surgery, published by Elsevier.
Scientists have found a potential new drug for treating the heart damage caused by a heart attack by targeting the way the heart reacts to stress.
