Cardiovascular Flashcards
What is ACS?
Acute coronary syndrome represents a spectrum of disease process resulting from insufficient blood flow to the coronary arteries.
What is Angina?
Angina is pain resulting from a temporary increased in MVO2, this may be the result of decreased blood flow in the coronary arteries due to narrowing or spasm.
What is an NSTEMI?
NSTEMI is the result of an incomplete occlusion of a coronary artery either by a thrombus or in concert with vasospasm.
What is a STEMI?
Occurs when a coronary artery is completely occluded by a thrombus. The Dx requires STE criteria to be met with elevation seen in 2 or more contiguous leads.
What is the definition of symptomatic bradycardia?
-HR less than 50
-Symptoms including but not limited to CP, DLOC, Nausea, SOB, hypotension and dizziness/light-headedness
What is the cumulative max dose for atropine?
3mg
When should an epi infusion be considered?
When atropine has been given but failed to produce a meaningful affect on BP and HR.
When should an epi infusion be considered?
When atropine has been given but failed to produce a meaningful affect on BP and HR.
What are 5 differential diagnosis for bradycardia
-MI
-Drug toxicity
-Hyperk
-Hypoxia in younger patients
-increased parasympathetic activity
Describe what happens to the aorta when an aneurysm occurs.
The intima of the aorta begins to tear and blood enters between the medial layer of the aortic wall, creating a false lumen.
What are 4 risk factors for acute aortic dissection?
HTN, Cardiac surgery, marfans, ehler-danlos syndrome
Is an ascending aortic dissection a type A or B dissection
Type A
What region does a type B dissection effect?
the descending/abdominal aorta
