https://medicalxpress.com/cardiology-news/ en-us Latest medical news and research in Cardiology New analyses from the Norwegian randomized controlled trial CARBFUNC show that more than doubling saturated fat intake over a two-year period can promote favorable changes in several cardiovascular risk markers, without increasing apoB, the main suspected risk factor. ApoB is a protein found in the particles that transport cholesterol in the blood and can be used to assess the risk of cardiovascular disease. https://medicalxpress.com/news/2026-10-carb-diet-high-saturated-fat.html Tue, 27 Oct 2026 18:20:08 EDT news712333261 A new national study found that hospitalizations for serious heart infections associated with drug use are declining after years of increases, driven largely by a decrease in opioid-associated cases. https://medicalxpress.com/news/2026-10-national-decline-drug-useassociated-heart.html Tue, 27 Oct 2026 18:00:05 EDT news712327712 With every heartbeat, blood is pumped through a vast network of vessels throughout our body, delivering vital oxygen, nutrients and other essential substances to even its most remote corners. But these vessels are far more than passive tubes: Their inner walls are covered by a thin layer of specialized cells called endothelial cells, which regulate blood flow, control what passes into surrounding tissues and help coordinate responses to injury. https://medicalxpress.com/news/2026-10-blood-vessels-age.html Tue, 27 Oct 2026 17:20:09 EDT news712332121 Researchers at the University of Manchester and Manchester University NHS Foundation Trust have uncovered a hidden defect in the tiny blood vessels of women with preeclampsia, a dangerous and common pregnancy complication that can threaten the lives of both mother and baby. https://medicalxpress.com/news/2026-10-blood-pressure-pregnancy-clue-door.html Tue, 27 Oct 2026 15:00:01 EDT news712327626 Just one session of heated tobacco product use results in measurable damage to the blood vessels, according to a study published today (Tuesday) in the European Journal of Preventive Cardiology. https://medicalxpress.com/news/2026-10-session-tobacco-blood-vessels-dna.html Tue, 27 Oct 2026 07:10:06 EDT news712299872 When it comes to blood clots, it is not only how they form that is crucial, but also how the body can break them down again. A team of researchers at the University of Koblenz, led by Prof. Dr. Marie-T. Hopp, has demonstrated that heme—a component of hemoglobin—can influence this process. The findings, published in the International Journal of Biological Macromolecules, provide a new molecular approach to better understanding the link between hemolysis and an increased risk of thrombosis. https://medicalxpress.com/news/2026-10-hemoglobin-component-heme-shown-inhibit.html Mon, 26 Oct 2026 20:40:06 EDT news712246098 Research led by internist-nephrologist Dr. Michele Eisenga shows that SGLT2 inhibitors, a class of drugs widely used to treat type 2 diabetes, heart failure and chronic kidney disease, consistently increase hemoglobin and hematocrit levels. https://medicalxpress.com/news/2026-10-large-meta-analysis-sglt2-inhibitors.html Mon, 26 Oct 2026 18:00:10 EDT news712252921 The American Heart Association, American Academy of Pediatrics, American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine have released a publication that redefines heart health in girls and women.

In hypertrophic cardiomyopathy, or HCM, treatment usually starts with medication. However, for some people, surgery becomes the best option when symptoms continue despite medical therapy, explains Joseph Dearani, M.D., a cardiovascular surgeon at Mayo Clinic in Minnesota. https://medicalxpress.com/news/2026-10-symptoms-surgery-decisions-people-thickened.html Wed, 21 Oct 2026 07:40:01 EDT news711780195 In a Journal of Internal Medicine study, people who drank tea had a lower risk of vascular disease than non-tea drinkers. https://medicalxpress.com/news/2026-10-tea-cardiovascular-disease.html Wed, 21 Oct 2026 03:00:02 EDT news711692508 Researchers at the UC Davis National Center for Interventional Biophotonic Technologies (NCIBT) have concluded the first-in-human test of a new device that could help doctors better detect and treat atherosclerosis, the narrowing of blood vessels due to plaque buildup. The flexible catheter-based device, developed at NCIBT labs, is designed to navigate the interior walls of arteries and capture detailed information about plaque buildup in real time. https://medicalxpress.com/news/2026-10-human-dual-imaging-catheter-heart.html Tue, 20 Oct 2026 23:40:02 EDT news711719377 In the event of a heart attack, the affected part of the heart muscle can no longer be supplied with oxygen and nutrients. As a result, the heart muscle cells (cardiomyocytes) die off. Scar tissue forms, and heart function is impaired. This often leads to chronic heart failure—also known in medical terms as cardiac insufficiency. It is one of the most common causes of death in the Western world. https://medicalxpress.com/news/2026-10-cell-therapy-cardiac-muscle-aggregates.html Tue, 20 Oct 2026 17:40:08 EDT news711722281 Researchers are investigating whether the body's built-in response to low oxygen can be harnessed to reduce heart damage during heart attacks and surgery, using drugs that are already available. https://medicalxpress.com/news/2026-10-harnessing-heart-natural-defense.html Tue, 20 Oct 2026 16:40:01 EDT news711720781 Gene therapy is no longer the future of medicine—it's reality.

Mostafa Al-Alusi, M.D., M.S., and Patrick T. Ellinor, M.D., Ph.D., of the Mass General Brigham Heart and Vascular Institute, are the lead and senior authors of a paper published in Nature Cardiovascular Research, "Deep Learning-Enabled Assessment of Right Ventricular Size and Function is Associated with Cardiovascular Outcomes." https://medicalxpress.com/news/2026-10-qa-ai-tool-automates-echocardiogram.html Tue, 20 Oct 2026 16:00:10 EDT news711719551 Using a high-throughput technique, an international collaboration led by Vanderbilt Health researchers has created a "map" of 1,757 genetic variations that can trigger a life-threatening heart rhythm disorder called long QT syndrome. https://medicalxpress.com/news/2026-10-gene-variants-sudden-death.html Tue, 20 Oct 2026 14:20:06 EDT news711719385 Testosterone therapy is not routinely recommended for postmenopausal women, in part because long-term safety data remain limited. It is, however, prescribed off label to help women suffering from low libido. A new study links testosterone therapy in postmenopausal women with a higher risk of incident cardiovascular disease. Results of the study were presented at the 2026 Annual Meeting of The Menopause Society in San Diego, Oct. 20–24, 2026. https://medicalxpress.com/news/2026-10-testosterone-therapy-cardiovascular-disease-postmenopausal.html Tue, 20 Oct 2026 12:00:18 EDT news711700148 A trip to Mars may be more feasible than previously thought, suggests a new study led by Northwestern Medicine, UT Southwestern and UT Houston that tracked the heart function of 13 astronauts during roughly six-month missions aboard the International Space Station. https://medicalxpress.com/news/2026-10-heart-astronauts-tolerate-mars-gravity.html Tue, 20 Oct 2026 11:40:05 EDT news711714123 Premature menopause is associated with an increased risk of several long-term health problems due to estrogen deficiency. Cardiovascular disease (CVD) is one of those health risks. However, the underlying cardiometabolic causes are unclear. A new study suggests a possible connection with insulin levels. Results of the study were presented at the 2026 Annual Meeting of The Menopause Society in San Diego, Oct. 20–24, 2026. https://medicalxpress.com/news/2026-10-premature-menopause-higher-insulin-greater.html Tue, 20 Oct 2026 11:00:10 EDT news711697394 For older adults with heart failure (HF), leaving the hospital alive does not always mean returning to an independent life. Loss of independence can reduce quality of life, increase caregiver burden and raise care needs. Yet most prognostic approaches focus on death or rehospitalization, making it difficult to identify patients likely to survive while losing independence. https://medicalxpress.com/news/2026-10-machine-hidden-functional-decline-heart.html Tue, 20 Oct 2026 10:00:06 EDT news711706770 Australia's updated cardiovascular disease risk calculator is identifying substantially more Australians aged 45–74 as being at "intermediate" risk of heart attack and stroke, according to new analysis published in the Medical Journal of Australia.
