A simple genetic test can identify those risks early, creating opportunities to prevent disease or detect it sooner—but only if it reaches the people who could benefit. https://medicalxpress.com/news/2026-07-populationwide-dna-screening-genetic-major.html Mon, 13 Jul 2026 11:00:06 EDT news702890222 The incidence of cardiovascular disease is rising across the globe, with more than 28 million people worldwide living with heart valve disease. Each year in the United States alone, surgeons perform approximately 106,000 heart valve replacement procedures. https://medicalxpress.com/news/2026-07-year-surgical-valve-heart-surgery.html Mon, 13 Jul 2026 07:10:01 EDT news703144620 People with chronic kidney disease (CKD) have a significantly increased risk of death from cardiovascular disease. They also suffer from chronic inflammation, the causes of which are still only partly understood. Oxalic acid (oxalate) has so far been known primarily for its role in the formation of kidney stones. The molecule is a natural metabolic byproduct, is found in certain foods and is normally excreted by the kidneys in urine. However, when kidney function is impaired, oxalate accumulates in the body and can promote inflammatory processes. https://medicalxpress.com/news/2026-07-oxalate-buildup-triggers-inflammation-cardiac.html Fri, 10 Jul 2026 15:40:03 EDT news702908086 People with severe obesity who exercise regularly have healthier blood vessels and lower inflammation than those who rely on medication alone, a new study from the University of Copenhagen shows. https://medicalxpress.com/news/2026-07-weight-loss-cardiovascular-health-medication.html Wed, 08 Jul 2026 12:20:04 EDT news702724331 A major new study, published in The Lancet Diabetes & Endocrinology, has shown that cortisol levels in patients with adrenal tumors are far less stable than previously assumed. The study also found that those in whom cortisol remains persistently elevated carry a significantly greater risk of worsening high blood pressure and a heavier overall cardiometabolic burden. https://medicalxpress.com/news/2026-07-silent-hormone-adrenal-tumors-quietly.html Tue, 07 Jul 2026 18:30:04 EDT news702630385 A clinical trial led by St. Michael's Hospital researchers found that using nerve blocks, an anesthesia technique to numb targeted areas of the body, significantly reduced opioid use after cardiac surgery—findings the authors say could reshape how the potentially addictive drugs are used after open-heart surgery. https://medicalxpress.com/news/2026-07-clinical-trial-strong-evidence-nerve.html Tue, 07 Jul 2026 13:20:10 EDT news702648275 A study led by the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), working in collaboration with an international research team, has identified a new molecular mechanism involved in hypertrophic cardiomyopathy, the most common inherited cardiovascular disease. https://medicalxpress.com/news/2026-07-heart-disease-mechanism-revealed-generation.html Tue, 07 Jul 2026 05:00:12 EDT news702537989 A new study published in Nature Communications identifies a molecular signaling pathway that contributes to the development of life-threatening aortic aneurysms and dissections in Marfan syndrome, a genetic disorder affecting connective tissue. The findings provide new insight into how structural alterations in the aortic wall lead to disease progression and point to potential therapeutic targets. https://medicalxpress.com/news/2026-07-fibronectin-pathway-marfan-aortic-drug.html Mon, 06 Jul 2026 14:40:06 EDT news702563602 Millions of people rely on statins, a medication used to lower cholesterol and reduce the risk of heart attack and stroke. But for some, the drugs come with an unwelcome trade-off: muscle pain, weakness and exercise intolerance that can make it difficult to continue treatment. Now, researchers at McMaster University have uncovered a biological pathway that may explain why those side effects occur, opening the door to future therapies that could make statins easier to tolerate while maintaining their lifesaving cardiovascular benefits. https://medicalxpress.com/news/2026-07-uncover-muscle-pain-widely-cholesterol.html Mon, 06 Jul 2026 13:30:01 EDT news702562778 In the event of a severe heart attack, immature immune cells are released into the bloodstream from the bone marrow. A research team led by the University of Münster has demonstrated that the maturity level of neutrophils can be used to determine the short-term risk of death, and this can be assessed through a simple blood test. These findings have been published in the journal Nature Cardiovascular Research. https://medicalxpress.com/news/2026-07-immature-immune-cells-chances-survival.html Fri, 03 Jul 2026 13:40:01 EDT news702290327 The children of mothers born with heart defects face a higher risk of being developmentally vulnerable, meaning they face challenges related to physical health, emotional maturity and communication, according to a new study led by Muhammad Zakir Hossin of the Karolinska Institutet, published in PLOS Medicine. https://medicalxpress.com/news/2026-07-congenital-heart-defects-mothers-developmental.html Thu, 02 Jul 2026 14:00:08 EDT news702204541 A "polypill" combining three medications recommended to treat heart failure into a single daily dose proved far more effective for patients than taking the drugs separately, a randomized clinical trial led by UT Southwestern Medical Center researchers showed. The findings, published in Nature Medicine, could lead to new ways to treat patients with conditions that require taking multiple daily medications to achieve optimal outcomes. https://medicalxpress.com/news/2026-07-polypill-heart-failure-hospitalizations-er.html Thu, 02 Jul 2026 13:20:07 EDT news702216901 Over the last three decades, differences in unhealthy cholesterol levels and blood pressure between older adults with obesity and those with a normal body mass index (BMI) have narrowed or disappeared in several high-income countries, suggests a study published in The Lancet. The authors propose that this trend is due to the greater, and possibly more intensive, use of cholesterol-lowering medication (such as statins) and blood pressure medication in people older than 40 living with obesity in high-income countries. https://medicalxpress.com/news/2026-07-heart-markers-adults-obesity-converge.html Wed, 01 Jul 2026 18:30:03 EDT news702116581 Individuals with atrial fibrillation (Afib), or irregular heart rhythm, are at increased risk of stroke, chronic kidney disease and heart failure. These risks are significantly exacerbated if a type 2 diabetes diagnosis is added to the mix, says Md Mohaimenul Islam, Ph.D., research assistant professor in the Department of Pharmacy Practice in the University at Buffalo School of Pharmacy and Pharmaceutical Sciences. https://medicalxpress.com/news/2026-07-glp-drugs-outperform-sglt-patients.html Wed, 01 Jul 2026 15:20:07 EDT news702128552 Researchers at UNSW Sydney have developed a fully synthetic soft robotic heart that reproduces the complex movements and internal structures of the human heart, opening the door to better treatments, safer medical devices and more personalized care. https://medicalxpress.com/news/2026-07-soft-robotic-heart-disease-life.html Wed, 01 Jul 2026 11:20:06 EDT news702122520
