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.
