Most heart attacks result from the formation of blood clots in the arteries that supply blood to the myocardium.

Some researchers reported at the American Heart Association meeting last year that at One hour after the onset of a heart attack in a dog, tissue plasminogen activator is administered to prevent death of the heart tissue. Researchers at Johns Hopkins University (USA) prepared tissue plasminogen activator The success of a small number of heart attack patients at the Baltimore City Hospital researchers at Washington University in St. Louis and University of Leuven in the March 8th issue of the New England Journal of Medicine reported that the culture of fine
