AFib is a condition in which the upper chambers of the heart beat out of rhythm with the lower chambers, leading to less efficient blood flow. It is usually the result of age and the lifelong cardiovascular strains on an older heart, but some families carry a rare mutation that puts them at high risk for AF much earlier in life, raising the risk of complications such as stroke or even sudden death. https://medicalxpress.com/news/2026-07-irregular-heartbeat-years-early-people.html Fri, 31 Jul 2026 08:40:06 EDT news704705641 The complexity of superior-inferior ventricles—a condition in which one ventricle is positioned on top of the other—has often limited surgical treatment. https://medicalxpress.com/news/2026-07-biventricular-linked-outcomes-superior-inferior.html Fri, 31 Jul 2026 08:40:03 EDT news704700901 Many people who survive a heart attack will later develop heart failure due to the scarring that occurs as the heart heals. Researchers at Uppsala University are now presenting a new type of biological treatment that is administered directly into the damaged blood vessel and stimulates healing. In the study, they also demonstrate how a new PET (Positron Emission Tomography) method can be used to identify patients with ongoing scarring and, ultimately, enable personalized treatment. https://medicalxpress.com/news/2026-07-exosome-treatment-curb-heart-scarring.html Thu, 30 Jul 2026 16:40:08 EDT news704647921 Cardiovascular disease (CVD) is among the leading causes of death worldwide. In South Korea, it is the second-leading cause of death, and its incidence has continued to rise in recent years.

To support the large, hardworking hearts that power other organs, heart cells have evolved to be extremely efficient and resilient. Because the adult human heart cannot repair itself the way skin does, scientists have studied ways to "reprogram" heart cells to regenerate after heart attacks. Heart cells have very stable identities, however, and are resistant to reprogramming. https://medicalxpress.com/news/2026-07-mechanism-reveals-heart-cells-resist.html Wed, 29 Jul 2026 13:00:04 EDT news704548622 Women who reach menopause before age 40 face a meaningfully higher risk of developing high blood pressure than those who go through menopause after age 45, according to a new study of more than 107,000 women. Risk peaked among women who reached menopause prematurely between ages 25 and 35. The results are published in Menopause in the article "Premature menopause is associated with the development of high blood pressure: a UK Biobank cohort study." https://medicalxpress.com/news/2026-07-premature-menopause-high-blood-pressure.html Wed, 29 Jul 2026 08:20:01 EDT news704529652 Cardiomyopathies are a group of mostly hereditary, rare heart diseases in which the structure of heart muscle tissue is impaired.

The targets appear to have had minimal impact, according to a study comparing the sodium content of new products introduced before and after the guidance was issued. https://medicalxpress.com/news/2026-07-fda-issued-sodium-yield-apparent.html Sat, 25 Jul 2026 09:20:01 EDT news704103660 A Cleveland Clinic-led study shows a connection between elevated blood levels of TMAO (trimethylamine N-oxide)—a byproduct of gut bacteria digestion of nutrients found in red meat and other animal products—and a higher risk of atrial fibrillation. https://medicalxpress.com/news/2026-07-red-meat-gut-byproduct-higher.html Fri, 24 Jul 2026 12:00:01 EDT news704107995 Cardiovascular conditions such as strokes or heart attacks are among the most common causes of death in Germany. Today, treatment and prevention are primarily based on so-called platelet aggregation inhibitors and anticoagulants—types of medication commonly referred to as blood thinners. They inhibit or prevent blood coagulation, which in turn prevents the formation of blood clots and life-threatening medical emergencies such as strokes or heart attacks. However, by intervening directly in the hemostasis process, they increase the risk of dangerous bleeding. https://medicalxpress.com/news/2026-07-natural-clotting-day-reliance-blood.html Thu, 23 Jul 2026 18:00:06 EDT news704043781 Congenital heart disease is the most common birth defect, affecting approximately 1 in 100 babies born each year.
