https://medicalxpress.com/cardiology-news/ en-us Latest medical news and research in Cardiology Glycoprotein VI, or GPVI for short, is a surface receptor found exclusively on platelets and their precursor cells, megakaryocytes in the bone marrow. GPVI is primarily responsible for binding collagen at the site of an injured blood vessel, which triggers the activation and aggregation of platelets. https://medicalxpress.com/news/2026-08-platelet-approach-path-safer-thrombosis.html Fri, 14 Aug 2026 13:40:01 EDT news705930721 QIMR Berghofer researchers have created the most detailed map yet of the chemical signals that control heart function, opening new avenues for the diagnosis, treatment and prevention of heart disease. https://medicalxpress.com/news/2026-08-heart-atlas-drugs-muscle.html Thu, 13 Aug 2026 15:00:07 EDT news705844022 Taking the stairs could help you live longer—according to new research from the University of East Anglia and the Norfolk and Norwich University Hospital. The study, published today, suggests that climbing stairs significantly reduces the risk of dying from cardiovascular disease. https://medicalxpress.com/news/2026-08-stairs-early-death.html Wed, 12 Aug 2026 19:10:03 EDT news705671582 If you see a doctor regularly, chances are you have had a lipid panel ordered and your blood drawn at a lab. The results told your physician your levels of cholesterol and triglycerides, factors that play a role in diagnosing conditions such as cardiovascular diseases and diabetes. Now, a team led by Wei Gao, a professor in Caltech's Cherng Department of Medical Engineering, has developed a stick-on patch capable of gathering the same lipid measurements by analyzing sweat. And it can do so not just once but continuously. https://medicalxpress.com/news/2026-08-sensor-enables-noninvasive-cholesterol.html Wed, 12 Aug 2026 16:20:01 EDT news705765645 Coronary artery disease, which is caused by plaque buildup in the arteries that supply blood to the heart, can appear stable for long periods without causing any symptoms. But the disease can become unstable at any time and cause a heart attack. Following a heart attack, low-grade inflammation can persist in the body for several months or even years. A large body of research suggests that this prolonged inflammation increases the risk of another heart attack. More than 20,000 people in Sweden suffer a heart attack every year. https://medicalxpress.com/news/2026-08-dysregulated-immune-cells-silent-inflammation.html Wed, 12 Aug 2026 14:40:04 EDT news705763681 Stopping statins in adults 75 and older with no history of heart disease or stroke does not increase the risk of death over three years compared with continuing statins, although "bad" cholesterol rose around 50% in those who stopped, according to a randomized controlled trial published in The Lancet Healthy Longevity. Statins are a key medication for the prevention of atherosclerotic cardiovascular disease, a specific type of cardiovascular disease caused by the buildup of fatty plaque (atherosclerosis) inside the arteries. https://medicalxpress.com/news/2026-08-adults-older-statins-similar-year.html Wed, 12 Aug 2026 11:40:09 EDT news705746206 Habitual cannabis users experienced about 9% fewer premature heartbeats on days they inhaled cannabis compared with days they abstained, a counterintuitive finding that adds to the complex and evolving understanding of how cannabis affects the heart, according to new UC San Francisco-led research. https://medicalxpress.com/news/2026-08-unexpected-insight-cannabis-heart-health.html Wed, 12 Aug 2026 10:00:04 EDT news705743761 Melbourne researchers have created human heart valve tissues from stem cells, providing a powerful new platform to advance treatments for childhood heart diseases. https://medicalxpress.com/news/2026-08-stem-cells-humanlike-heart-valve.html Tue, 11 Aug 2026 16:20:06 EDT news705680461 A multidisciplinary, multi-institution group of researchers focused their expertise in genetics, mechanics, chemistry and biology on a chip the size of a postage stamp to model a particular class of heart conditions. https://medicalxpress.com/news/2026-08-heart-assembloids-valve-disorders.html Tue, 11 Aug 2026 11:00:06 EDT news705586681 There are people around us who can maintain their weight despite what they eat. This has led scientists to believe that a person's metabolism and tendency toward obesity may have genetic factors behind them. A large study sequencing the genomes of more than 1 million people across three continents, found genetic clues that could drive this tendency. The findings are published in Nature. https://medicalxpress.com/news/2026-08-people-rare-gene-variant-naturally.html Mon, 10 Aug 2026 15:40:01 EDT news705585086 A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection. https://medicalxpress.com/news/2026-08-molecular-reveals-hidden-cellular-heart.html Mon, 10 Aug 2026 05:00:01 EDT news705321148 Each year, more than 250,000 people in the United States experience out-of-hospital cardiac arrests. Approximately 90% of patients do not survive. https://medicalxpress.com/news/2026-08-trial-focuses-duration-therapeutic-hypothermia.html Thu, 06 Aug 2026 16:00:02 EDT news705248807 A new study, published in Neurology Open Access, shows an association between three common vascular risk factors and the amount of dementia-free time people experience after age 55. The study hints that dementia is not inevitable and that addressing some modifiable vascular risks around or before midlife might extend dementia-free life for years. https://medicalxpress.com/news/2026-08-common-midlife-vascular-factors-dementia.html Thu, 06 Aug 2026 13:20:09 EDT news705235321 During development, regional dips in oxygen levels serve as a signal that triggers the coordinated growth of heart muscle and coronary vessels, according to a study led by researchers at Weill Cornell Medicine. The findings, published online in the Proceedings of the National Academy of Sciences, could point toward innovative approaches for treating cardiovascular conditions that lead to heart failure. https://medicalxpress.com/news/2026-08-oxygen-synchronize-heart-muscle-blood.html Thu, 06 Aug 2026 12:00:07 EDT news705235382 Adding the GLP-1 receptor agonist drug tirzepatide (marketed as Mounjaro) to standard care for patients with type 2 diabetes and heart disease is associated with a lower risk of a major cardiovascular event, such as a heart attack or stroke, finds a study published by The BMJ today. https://medicalxpress.com/news/2026-08-glp-drug-linked-heart-benefits.html Wed, 05 Aug 2026 18:30:01 EDT news705074821 Congenital heart disease affects approximately two in every 100 newborns globally. But why does it occur? An important part of the answer may lie in a previously unknown mechanism on the surface of our cells. Researchers from the University of Copenhagen identified this mechanism in a new study. https://medicalxpress.com/news/2026-08-uncover-hidden-mechanism-congenital-heart.html Tue, 04 Aug 2026 14:00:05 EDT news704993941
