Early treatment of heart attack patients with an inexpensive beta-blocker drug called metoprolol, while in transit to the hospital, can significantly reduce damage to the heart during a myocardial infarction, according to clinical trial/study results published Oct. 1 in the journal Circulation. The study was a collaboration between Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) and Icahn School of Medicine at Mount Sinai.
