What are the medical procedures used on a patient having a heart attack. are there any preventive measures used to ease the pain of this attack?

Yes: During an acute mi (myocardial infarction), efforts will be made to reduce the size of the damaged area by giving antiplatelet drugs, and clot busters. Many patients will have emergency coronary angiogram to open up blocked arteries and place stents to help keep the arteries open. This is why it is important to get to a hospital immediately at the first sign of a mi.

Multiple: Aspirin, hospital, catheterization, clot lysis therapy, balloon or stents, and occasionally surgery.
