Study shows how early administration of old drug reduces damage during heart attack
Scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have discovered a new mechanism of action of metoprolol, a drug that can reduce the damage produced during a heart attack if administered early. The team led by Dr. Borja Ibáñez, Clinical Research Director at the CNIC and cardiologist at the Fundación Jiménez Díaz University Hospital Health Research Institute (IIS-FJD), has identified the mechanism that explains why this drug is so beneficial: rapid administration of metoprolol during a heart attack directly inhibits the inflammatory action of neutrophils, a type of blood cell. The reduced inflammation translates into a smaller area of damaged tissue in the post-infarcted heart. The finding, published in Nature Communications, opens the way to new applications for this cheap, safe, and simple drug.
