Can aspirin be given in an ambulance or at home in patient suspected to have had a heart attack?

In this video, Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will discuss whether an aspirin can prevent a heart attack if given in ambulance or at home if suspected to have heart attack in a patient.  At the diagnosis of a heart attack, the patient should be given water soluble 300mg of aspirin wherever the patient gets it. All heart patients should keep the strip of aspirin in their pocket or at home or in car or office. All doctors should also keep a strip in their clinic or car.
