The results of the international study are published in the journal Cardiovascular Research. https://medicalxpress.com/news/2026-05-heart-chambers-severely-affected-atrial.html Thu, 21 May 2026 10:40:04 EDT news698576311 A number of previous studies have shown that young male endurance athletes and young men in general with high fitness levels appear to have an increased risk of developing atrial fibrillation later in life compared to non-athletes and those with low fitness levels. But to what extent is this true? https://medicalxpress.com/news/2026-05-men-smaller-atrial-fibrillation-heart.html Thu, 21 May 2026 05:00:10 EDT news698515922 A team of researchers from Carnegie Mellon University, in collaboration with Cleveland Clinic's Cardiovascular Innovation Research Center, has developed an artificial intelligence (AI) system capable of interpreting some of the most complex heart scans in medicine, cardiac magnetic resonance imaging (MRI), without the need for manually labeled training data. https://medicalxpress.com/news/2026-05-ai-cardiac-mri-manual-general.html Thu, 21 May 2026 05:00:03 EDT news698480052 A new study from Karolinska Institutet shows that people's own reports of heart attacks in the family only partially correspond with register data. The findings suggest that heart attacks among relatives are often underreported, particularly for events occurring early in life. The results, published in European Journal of Epidemiology, show that the agreement between self-reported data and register data was only moderate. https://medicalxpress.com/news/2026-05-family-history-underestimates-heart.html Wed, 20 May 2026 20:40:01 EDT news698491838 Eating foods that contain common preservative food additives may increase the risks of high blood pressure and cardiovascular disease, according to research published in the European Heart Journal. https://medicalxpress.com/news/2026-05-common-food-linked-high-blood.html Wed, 20 May 2026 19:00:01 EDT news698479766 Myocardial infarction remains one of the leading causes of death worldwide. Following an infarction, part of the heart muscle is irreversibly damaged and replaced by scar tissue, which, while structurally necessary, compromises cardiac function and may lead to chronic heart failure. https://medicalxpress.com/news/2026-05-cardiac-organoids-potential-myocardial-infarction.html Wed, 20 May 2026 17:20:02 EDT news698506261 In a 2026 study I conducted with colleagues on people with peripheral arterial disease, one participant described how leg pain had disrupted his golf for years. It forced him to stop mid-round, shake his leg and apologize to his playing partners while he waited for the pain to pass. He found it mortifying. Then he tried a small electrical device that delivered gentle pulses through pads stuck to his skin. He still had pain. But he could get round the course. https://medicalxpress.com/news/2026-05-chronic-pain-treatment.html Wed, 20 May 2026 16:40:08 EDT news698501702 UBC Okanagan researchers, working with scientists at BC Cancer–Kelowna, have developed a groundbreaking AI model that can help identify breast cancer patients who may face a double-threat—that of cancer and cardiovascular disease. https://medicalxpress.com/news/2026-05-ai-flags-heart-breast-cancer.html Wed, 20 May 2026 15:00:11 EDT news698501101 Researchers at Mass General Brigham Heart and Vascular Institute found that people with hepatic steatosis, commonly called "fatty liver disease," have a higher amount of noncalcified, rupture-prone coronary plaque and face nearly twice the rate of cardiovascular events compared to those without steatosis. https://medicalxpress.com/news/2026-05-illuminates-link-fatty-liver-disease.html Wed, 20 May 2026 11:00:01 EDT news698401205
