Wk1: ACS, MI, cardiac issues Flashcards
Differentiate between acute and chronic pericarditis.
what is the beck of triad?
When does it occur?
- hypotension (d/t decreased CO)
- JVD (d/t blood back flow)
- muffled heart sounds (d/t fluid buildup)
-occurs with cardiac tamponade
What is pulsus paradoxus?
happens in 70-80% of cardiac tamponade Pts
decreased systolic blood pressure of 10mm Hg or more with inspiration
**easier to see with Arterial line placement
typical manifestations of acute pericarditis.
-CP (sharp and worsens with deep breath)
-fever
-dyspnea
-pericardial friction rub: scratching sound heard
-ST elevations on EKG
Tx for pericarditis
NSAIDs
ASA
corticosteroids
Colchicine (if NSAIDs don’t work)
pericardial effusion
the fluid accumulated in the pericardial space, surrounding the heart
cardiac tamponade
> 200mLof fluid accumulation
-compressing the heart
-changes ability of heart to pump accurately
-cannot stretch and fill with blood
etiologies/pathogenesis of aortic aneurysms
-changes occur in vessel (d/t HTN)
-vessel wall gets thicker
-vessel starts to burst, causing abnormalities
-aneurysms cause turbulent blood flow & are susceptible to rupture
etiology/pathogenesis of aortic dissection
blood gets between layers of the vessels and it rips layers apart
what is the most common location for a berry aneurysm?
circle of Willis
-most common bifurcation location, located between anterior and posterior circulation at base of brain
-deadly with rupture
pseudo-aneurysm:
localized dissection in inner artery wall
-type of hematoma
-complication of vascular interventional procedure
Differentiate between the various types of aneurysms, including saccular, berry, and
fusiform.
saccular: wide neck with ball on top, only on one side of the artery
Berry: subtype of saccular, small neck, located at bifurcation
fusiform: surrounds entire artery, gradually progressive dilation
Describe LaPlace Law
Differentiate between true and false aneurysms.
clinical manifestations of abdominal aortic aneurysm
bruit
pulsatile mass
clinical manifestations of TA
characteristics of unstable plaque
pathophysiologic theory of plaque rupture
Describe the most important serum cardiac marker, including its significance, and when it can be
measured.
difference between cardiac ischemia and cardiac infarction
when does an irreversible injury occurs.
Differentiate between stable angina and acute coronary syndrome

-Pathogenesis
-common characteristics ?
Reason unstable angina and acute MI have been grouped together as ACS
Differentiate between unstable angina and acute myocardial infarction, including aspects of
occlusion and thrombus, ECG changes, and cardiac enzyme changes
