Researchers at the Austrian Academy of Sciences have developed the most realistic cardiac organoids to date. The tiny structures self-organize from pluripotent stem cells to form a hollow chamber that can beat. The method to create the ‘cardioids’ involves stimulating a variety of signaling pathways in stem cells and does not rely on conventional tissue… Read More »
(SACRAMENTO, Calif.) — Continuous indoor exposure to second-hand tobacco smoke triggers changes in the heart’s electrical activity, known as cardiac alternans, that can predict cardiac arrhythmia and sudden cardiac death, a new study from UC Davis Health researchers shows. The authors believe the study, conducted in mice, suggests that second-hand smoke exposure alters cells that regulate… Read More »
Image The rate of sudden cardiac death in African-Americans is twice as high as in whites, and no one knows why. Sudden cardiac death is an unexpected fatality from cardiac causes that happens within an hour of the onset of symptoms, usually with no known cause. For more than six years, researchers followed 9,416 blacks… Read More »
A study that followed over 21,000 male doctors for two decades, measuring a variety of things including the influence of carrying a few extra pounds and physical activity on risk of cardiac heart failure has an important message – even a few extra pounds can be risky, especially if you’re not active. For the non-medical… Read More »
