Lilly’s obesity drug retatrutide, which previously showed rapid weight loss and diabetes benefits, yielded new safety data at the ADA meeting and in Lancet: in TRANSCEND-T2D-1, 7 of 403 participants on retatrutide had arrhythmias and 3 had major cardiovascular events versus none on placebo, a small event count that experts say is insufficient to draw firm cardiovascular risk conclusions.
New research from Karolinska Institutet and Columbia University reveals that the heart has its own complex nervous system, or "mini-brain," capable of independently regulating the heartbeat. This discovery, made through studies on zebrafish, challenges traditional views and could lead to new treatments for heart diseases like arrhythmias. The study highlights the heart's neural network's complexity and its potential interaction with the brain during stress or disease, offering new therapeutic targets.
Scientists have used gene editing to create heart muscle cells that reduce arrhythmias by 95% in pigs, according to a study in the journal Cell Stem Cell. Researchers at the University of Washington discovered that cardiomyocyte injections cause arrhythmias because the cells are immature, so they fail to harmonise with the heart’s electrical system and force the organ to beat too quickly. The scientists started with human embryonic stem cells, which have the potential to become any of the 200 different cell types in the body, and altered different combinations of genes to create the new cells.
