Muscle protein abundant in the heart plays key role in blood clotting during heart attack

(Scripps Research Institute) A prevalent heart protein known as cardiac myosin, which is released into the body when a person suffers a heart attack, can cause blood to thicken or clot--worsening damage to heart tissue, a new study shows. A team led by John H. Griffin, PhD, a professor in the Department of Molecular Medicine at Scripps Research, made the unexpected finding after a series of experiments spanning three years and involving researchers from multiple collaborating institutions.
