recently my grand father had chest pain and was rushed to emergency department, there they took ECG and told it is pretty much ok and he as suffered angina, not heart attaok. they put him on injectable blood thinning drugs and than latter discharged with oral blood thining drugs. it also contains aspirin which i used to take when ever i had head ache, the doctor told it has heart attack preventing properly also. do aspirin have that ? any body with angina is prescribed aspirin ?
