ACS PHARM Flashcards
Initial Treatment of Acute MI
- Oxygen
- Morphine (dilates vessels too)
- Aspirin (chew)
- Nitro
- Beta-blockers (dep HR)
- Thrombolytic agent (within 4-6 hrs of MI) if eligible*
STEMI Pharm: Immediate
MONAB
- O2
- increases o2 delivery to ischemic area - Aspirin
- Suppresses platelet aggregation (chew)
- decreases mortality - Morphine
- Decreases pain, reduces preload + afterload
- Helps preserve ischemic tissue - Beta Blocker
- reduce HR and contractility (reduce o2 demand)
- Reduces pain, infarct size, and mortality - Nitroglycerine
- Reduces preload + afterload
- limits infarct size
- Does NOT reduce mortality
STEMI: Fibrinolytic Therapy
Ateplase (tPA)
MOA: Dissolves clot by converting plasminogen to plasmin
Advantage: most effective
Disadvantage: BEST if within 30-70 mins
AE: Bleeding
**Always given with: Heparin and Antiplatelet therapy
Nitroglycerine A/E
AE: Severe Hypotension
-particularly with other nitrates or (Cialis, Viagra)
Reperfusion Injury
Rapid restoration of blood flow to the myocardium also contributes to injury of MYOCARDIAL STUNNING
Caused by oxidized free radicals generated by WBCs and the cellular response to restored blood flow
KEY INFORMATION
Acute MI is leading cause of death in US
Hesitation or delayed request for emergency care are the major causes of death due to MI
Survival rates for treated patients with acute MI are 90-95% in the US
50% of people who have MI are younger than 65
Persons with diabetes and those older than 65 often suffer silent asymptomatic MI YIKES
