https://medicalxpress.com/cardiology-news/ en-us Latest medical news and research in Cardiology A cross-university paper led by researchers at Queen Mary University of London, published in the Journal of Physiology, shows how better "digital twins" could help doctors treat people with atrial fibrillation. https://medicalxpress.com/news/2026-06-heart-digital-twins-treatment-atrial.html Thu, 18 Jun 2026 08:20:03 EDT news700980542 A new gene therapy appears to be safe in patients diagnosed with Friedreich ataxia cardiomyopathy, a progressive and fatal inherited cardiac disease, according to a phase 1 clinical trial led by Weill Cornell Medicine researchers. The treatment may also reduce heart damage, although further investigation is needed. https://medicalxpress.com/news/2026-06-gene-therapy-life-threatening-inherited.html Wed, 17 Jun 2026 15:00:06 EDT news700920001 Women who lift weights may have a lower risk of major heart disease, especially when combined with aerobic exercise, according to a new study published in JACC. Findings show that heart health is better understood by looking at overall movement habits, rather than focusing on single behaviors alone, and resistance training can result in additional health benefits when incorporated into an active lifestyle. https://medicalxpress.com/news/2026-06-strength-linked-heart-disease-women.html Wed, 17 Jun 2026 10:00:09 EDT news700901161 It is a common misperception that electrocardiograms (ECGs) simply contain data about heart activity. However, modern ECGs enhanced with artificial intelligence (AI) can contain data about a patient's sex, age, race and even exact identity derived from ECG signals, raising fresh privacy concerns. To address these worries, researchers from the University of Kansas have developed a privacy-preserving AI model called (PP-VAE) to protect personally sensitive data. https://medicalxpress.com/news/2026-06-ecg-privacy-shields-age-sex.html Tue, 16 Jun 2026 16:40:07 EDT news700844762 Men are overrepresented when it comes to heart disease, but there are certain conditions that mainly affect women, such as "broken-heart syndrome." Stress and anxiety are common in this group. A new study led by researchers at Uppsala University and Karolinska Institutet shows that internet-based cognitive behavioral therapy (CBT) can reduce symptoms and help patients manage their emotions better. https://medicalxpress.com/news/2026-06-online-cbt-eases-stress-broken.html Tue, 16 Jun 2026 14:00:03 EDT news700833866 A new study led by UCLA Health physician-scientists suggests that subtle changes in heart structure and function may signal an increased risk of developing certain cancers years later. The findings, published in the Journal of the American Heart Association, could eventually help physicians identify patients who may benefit from earlier prevention strategies aimed at both cardiovascular disease and cancer. https://medicalxpress.com/news/2026-06-early-heart-cancer-years-diagnosis.html Fri, 12 Jun 2026 11:40:04 EDT news700479121 Researchers from Amsterdam UMC have overturned a key assumption in the biological pacemaker field. In a new preclinical study, they show that the transcription factor TBX18 does not generate true biological pacemaker activity, while the ion channel Hcn2 does produce robust pacemaker function in the heart. The findings have been published in the Journal of Clinical Investigation. https://medicalxpress.com/news/2026-06-biological-pacemaker-dogma-tbx18-hcn2.html Thu, 11 Jun 2026 12:00:01 EDT news700321047 Healthy sleep and regular exercise can work to counteract genetic mutations in white blood cells that are associated with cardiovascular disease and are most common among older people, Mount Sinai researchers have found. In a study published in Nature, the team reported for the first time that sufficient sleep and exercise can help reduce the cancer-like cell expansion and atherosclerotic risk linked to mutations that spontaneously occur in white blood cells. https://medicalxpress.com/news/2026-06-curb-heart-mutant-white-blood.html Wed, 10 Jun 2026 15:40:03 EDT news700321651 Microtubules, part of heart muscle cells' internal "skeleton," help determine how the heart changes shape under stress, and a common signaling pathway called the ERK pathway acts as a key controller of where the building materials for these cells' growth are delivered inside them, a pair of new studies show. These findings, from a team at the Perelman School of Medicine at the University of Pennsylvania, point to possible new ways to address harmful heart remodeling that can be linked to heart failure. https://medicalxpress.com/news/2026-06-molecular-mechanics-heart-cell-revealed.html Tue, 09 Jun 2026 13:20:04 EDT news700228322
