https://medicalxpress.com/cardiology-news/ en-us Latest medical news and research in Cardiology Unlike adult hearts, the hearts of newborn mammals can temporarily regenerate after damage. However, this remarkable ability is rapidly lost within the first days of life. In a new study, scientists investigated how neonatal hearts respond to both heart injury and pressure overload, a condition that mimics chronic stress on the heart. https://medicalxpress.com/news/2026-08-tlr2-links-inflammation-neonatal-heart.html Mon, 17 Aug 2026 14:40:03 EDT news706190083 Wearable sensors coupled with AI can generate blood pressure readings nearly as accurately as the invasive and risky arterial lines relied on in intensive care units and operating rooms, new work by Johns Hopkins University researchers demonstrates. https://medicalxpress.com/news/2026-08-wearable-sensors-ai-blood-pressure.html Mon, 17 Aug 2026 10:00:06 EDT news706176122 When Mark Hughes, the former Manchester United and Wales manager, lost his 38-year-old son, an inquest found the cause was sudden adult death syndrome, or SADS. https://medicalxpress.com/news/2026-08-sudden-adult-death-syndrome.html Sun, 16 Aug 2026 15:00:01 EDT news705918322 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 An international study has found that despite two decades of global tobacco control efforts, the message still is not getting through to enough smokers that smoking and secondhand smoke cause heart attacks and strokes. https://medicalxpress.com/news/2026-08-smokers-largely-unaware-heart-disease.html Thu, 13 Aug 2026 10:20:01 EDT news705831198 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 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 Early natural menopause is already associated with a higher long-term health burden. A new large-scale study demonstrates that cumulative social disadvantage—and, in particular, unemployment—is strongly associated with an increased risk of all-cause mortality and cardiovascular disease, as well as a marked predisposition to dementia, in women with early natural menopause. https://medicalxpress.com/news/2026-08-social-disadvantage-greatly-amplifies-mortality.html Wed, 12 Aug 2026 09:40:01 EDT news705736038 People with both atrial fibrillation and Alzheimer's disease who are treated with modern NOAC blood-thinning medicines may experience a slower rate of cognitive decline. This is shown by a study from Karolinska Institutet published in the European Heart Journal. https://medicalxpress.com/news/2026-08-blood-thinning-medication-linked-slower.html Wed, 12 Aug 2026 07:00:03 EDT news705678182 Heart disease is the leading cause of death in the United States, according to the Journal of the American College of Cardiology. Its impact extends beyond biology, with social determinants such as food insecurity, socioeconomic status and education influencing outcomes. https://medicalxpress.com/news/2026-08-america-heart-disease-crisis-hypertension.html Tue, 11 Aug 2026 16:20:08 EDT news705678962 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 The size of a person's midsection is a better indicator of cardiovascular disease risk than body mass index (BMI) alone, according to a study published in JACC. BMI has traditionally been used to determine overweight or obesity, common risk factors for heart disease, but this study shows that not accounting for waist circumference (WC) or waist-to-hip ratio (WHR) can lead to misclassification of cardiovascular disease risk. https://medicalxpress.com/news/2026-08-abdominal-fat-heart-disease-bmi.html Tue, 11 Aug 2026 10:00:03 EDT news705580081 In a new Annals "Beyond the Guidelines" feature, a general internal medicine physician and a cardiologist discuss how to evaluate and manage perioperative cardiovascular risk in an older patient with multiple chronic conditions who is preparing for noncardiac surgery. Using the 2024 American Heart Association/American College of Cardiology guideline, which emphasizes a stepwise patient-centered and team-based approach to preoperative cardiac assessment, the experts explore how clinicians can balance the need for preoperative testing with the risks of unnecessary procedures and surgical delays. https://medicalxpress.com/news/2026-08-heart-surgical-delays-complex-preoperative.html Tue, 11 Aug 2026 08:40:01 EDT news705647582 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 Older adults with cardiovascular disease (CVD) often have coexisting cognitive impairment and frailty, conditions that can significantly affect treatment decisions, recovery, independence and quality of life and should be considered as part of an aging-informed approach to care, according to a new American College of Cardiology Scientific Statement published in Journal of the American College of Cardiology. https://medicalxpress.com/news/2026-08-cardiovascular-older-adults-account-cognitive.html Mon, 10 Aug 2026 10:00:04 EDT news705243860 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 A new study reveals that the cardioprotective drug dexrazoxane significantly reduces heart damage caused by chemotherapy in pediatric cancer patients 15 years or more after treatment ends. https://medicalxpress.com/news/2026-08-drug-dexrazoxane-heart-pediatric-cancer.html Fri, 07 Aug 2026 14:00:07 EDT news705328560 Understanding how heart muscle cells stop dividing and acquire the characteristics needed to sustain lifelong cardiac function remains one of the greatest challenges in cardiovascular biology. Leveraging human induced pluripotent stem (iPS) cell technology, a team led by Associate Professor Yoshinori Yoshida (Department of Clinical Application, CiRA, Kyoto University) and Associate Professor Antonio Lucena-Cacace (WPI-PRIMe, The University of Osaka) has identified PRDM16 as an important regulator governing the balance between proliferation and maturation in human iPSC-derived cardiomyocytes. https://medicalxpress.com/news/2026-08-growth-function-gene-human-heart.html Fri, 07 Aug 2026 12:40:01 EDT news705325083 Having high blood pressure is associated with greater intentions to follow doctors' recommendations to take medication but lower intentions to make recommended lifestyle changes than among people without high blood pressure, according to a new study published in Hypertension. https://medicalxpress.com/news/2026-08-greater-intentions-hypertension-medication-lifestyle.html Fri, 07 Aug 2026 08:20:01 EDT news705301261 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 New research from Keele University and the University of Aberdeen has found that men with cardiovascular disease are at higher risk of cancer and death from cancer than women. The study found this pattern across all cancer subtypes, with lung cancer and colorectal cancers accounting for the highest risk. https://medicalxpress.com/news/2026-08-link-heart-disease-cancer-deaths.html Thu, 06 Aug 2026 13:00:05 EDT news705236702 For many older adults with heart disease, age is a significant factor in treatment decisions. But a new Yale–led study published in the Journal of the American Geriatrics Society suggests that overall health, function and medical conditions may be more important than age alone when physicians and patients consider percutaneous coronary intervention (PCI), a common treatment for chronic coronary disease in which a small tube called a stent is placed inside an artery to help keep it open. https://medicalxpress.com/news/2026-08-age-treatment-decisions-chronic-coronary.html Thu, 06 Aug 2026 12:20:01 EDT news705236341 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 Type 2 diabetes is associated with an increased risk of heart disease. Many people with type 2 diabetes are prescribed blood sugar-lowering medication to reduce this risk. However, not everyone takes their medication consistently, and that inconsistency could leave them more exposed. https://medicalxpress.com/news/2026-08-term-diabetes-medication-adherence-linked.html Thu, 06 Aug 2026 11:44:55 EDT news705235381
