Columbia scientists discover surprising link between serotonin and heart valve disease

Scientists have found a surprising connection between serotonin, the brain chemical tied to mood regulation, and the progression of mitral regurgitation, a common heart valve disease. Their research indicates that individuals with this condition who use SSRI antidepressants and possess a particular genetic variant may experience more rapid valve damage, necessitating earlier surgeries. This discovery could change treatment strategies for patients and highlights the need for personalized medicine approaches to avoid exacerbating underlying heart conditions.
