What interventions are needed for coronary ischemia? - ANSWER - Stress echo, nuclear perfusion imaging or cardiac catheterization
What is stable angina? - ANSWER - Exercise-induced chest pain relieved by rest or nitroglycerin
What is unstable angina? - ANSWER - Angina that is either new in onset or differs from a patient's typical stable angina pattern. Pain at rest does not respond to nitroglycerin.Precursor to MI.
What causes unstable angina? - ANSWER - Rupture of plaque with w/thrombus and incomplete occlusion of coronary artery

Why are ACE inhibitors given for MI? - ANSWER - They help decrease left-ventricular remodeling, help decrease afterload
Why are statins given for MI? - ANSWER - They are anti-inflammatory, usually given 12- 24 hrs. after MI
What meds are given to prevent future MI? - ANSWER - Beta blockers, ACE inhibitors, statins
What variables do we monitor during chest pain for core measures? - ANSWER - EKG, Basic hemodynamics (Cardiac output, stroke volume)
What do anticoagulants do - ANSWER - Decreases the clotting (coagulating) ability of the blood. Sometimes called blood thinners, although they do not actually thin the blood.They do NOT dissolve existing blood clots. Used to treat certain blood vessel, heart and lung conditions.
Why prescribe anticoagulants? - ANSWER - Helps to prevent harmful clots from forming in the blood vessels. May prevent the clots from becoming larger and causing more serious problems. Often prescribed to prevent first or recurrent stroke.
