A stenosis is an abnormal narrowing in a blood vessel or other tubular organ or structure.
Research led by Henry Ford Health's Lalathaksha Kumbar, M.D., evaluated and validated a remote access monitoring technology that can predict vascular access blockages in dialysis patients.
A team from 15 U.S. medical centers led by UT Southwestern Simmons Cancer Center researchers has performed the first analysis of a potentially game-changing drug to treat upper urinary tract urothelial cancers.
Patients with congenital heart diseases often suffer from obstructions in the right ventricular outflow tract (RVOT), which carries blood from the heart to the lungs. These obstructions can be repaired with surgical procedures.
A recent study published in the Lancet journal investigated whether a quantitative in-silico score for coronary artery disease (ISCAD), based on a machine learning model, can be used as a clinical marker to detect coronary artery disease.
Using machine learning and clinical data from electronic health records, researchers at the Icahn School of Medicine at Mount Sinai in New York constructed an in silico, or computer-derived, marker for coronary artery disease (CAD) to better measure clinically important characterizations of the disease.
Cedars-Sinai investigators and colleagues have developed an artificial intelligence (AI) tool that uses computed tomography (CT) scans to identify patients at risk of reduced blood flow to the heart.
In a new study, researchers reported the mechanisms involved in COVID-19 coagulopathy and the significance of SARS-CoV-2 infections for cancer patients concerning outcomes, thromboembolic complication risks, and consequences of management strategies.
In one of the first studies to examine the relationship between different types of grain intake and premature coronary artery disease in the Middle East, researchers found a higher intake of refined grain was associated with an increased risk of premature coronary artery disease in an Iranian population, while eating whole grains was associated with reduced risk.
Minimally invasive, catheter-based transcatheter aortic valve replacement (TAVR) has revolutionized treatment of aortic stenosis (AS), and both American and European guidelines have approved its use. However, there is a perception that TAVR is more expensive than surgical aortic valve replacement (SAVR). A budget impact analysis comparing the two options now shows that TAVR is an affordable and effective strategy for the treatment of AS. The study appears in the Canadian Journal of Cardiology, published by Elsevier.
Aortic valve stenosis occurs when the aortic valve narrows, constricting blood flow from the heart through the artery and to the entire body.
A large-scale international study led by Mount Sinai has yielded the first risk score that can help predict mortality for patients with atrial fibrillation (AFib) who have undergone a successful transcatheter aortic valve replacement (TAVR) and discharged home.
A heart check-up is recommended in even apparently healthy people over 65 years of age before intermediate- or high-risk non-cardiac surgery, according to European Society of Cardiology (ESC) Guidelines on cardiovascular assessment and management of patients undergoing non-cardiac surgery published online today in European Heart Journal.
Motion analysis of video recorded on a smartphone accurately detected narrowed arteries in the neck, which are a risk factor for stroke, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.
Patients with a specific form of age-related macular degeneration (AMD), a leading cause of blindness in the United States, are at significant risk for cardiovascular disease and stroke, according to new research from New York Eye and Ear Infirmary of Mount Sinai.
Urgent action is needed to clear the backlog of people with a common heart condition who are waiting for lifesaving treatment, according to research co-led by a Keele Professor.
The risk of having a future stroke caused by a severe blockage in an artery in the neck that is not currently causing any symptoms is so low that most patients with this condition -; asymptomatic carotid stenosis -; could potentially be treated with the newest medications and may not require surgery, new Kaiser Permanente research suggests.
A study of one year outcomes in the largest cohort to date of Harmony transcatheter pulmonary valve (TPV) patients with congenital heart disease (CHD) and severe pulmonary regurgitation (PR) was presented today as late-breaking clinical research at the Society for Cardiovascular Angiography & Interventions 2022 Scientific Sessions.
Valve replacement heart surgery should be performed earlier than conventionally thought for people with aortic stenosis – according to new research from the University of East Anglia.
A study led by researchers at the National Institute for Health and Care Research Leicester Biomedical Research Centre has shown that a less invasive heart procedure for a common condition is just as effective as conventional open-heart surgery.
Medical interventions, such as improving diet, lowering blood lipids, or controlling blood pressure and blood sugar, can only do so much when it comes to treating atherosclerotic disease.
