K.R. is a 46-year-old man admitted to the emergency department with unremitting chest discomfort. The pain started while he was shoveling snow from his walkway. He had experienced chest discomfort with activity previously, but the pain had subsided with rest and he sought no medical help. This time the pain did not subside and became increasingly severe, radiating to his left arm and lower jaw. In the emergency department, an ECG and cardiac enzymes were obtained. The cardiac monitor showed sinus tachycardia with occasional premature ventricular complexes. After receiving results of his ECG and cardiac enzymes, the physician diagnoses K.R. with a myocardial infarction (MI). What drug treatment would you expect to administer for the pain associated with MI? Why? (List 2 drugs that would help treat the pain associated with MI. Explain why these drugs are helpful in reducing pain.) What medical treatment, other than medications, would you expect K.R. to undergo for MI? Briefly describe these treatments. (List and describe 2 medical treatments, other than medications, that K.R. may undergo for treatment of MI.)
