CV Pathology--Witrak Flashcards
Dressler’s pericarditis
autoimmune pericaridits after 4-6 wk post-MI
Left ventricular rupture post-MI
3-14 days after MI
macrophages eat up tissue
ventricular wall at its weakest
rupture fills pericaridal sac with blood, cardiac tampanade
If left ventricle fails, what is the first symptom?
pulmonary edema
pink, foamy fluid
Hepatomegaly in left ventricular failure
inferior vena cava backs up
Primary pathology of mitral valve stenosis
rheumatic fever –> rheumatic heart disease
S. aureus septisemia
in adults, what?
in children, what?
adults: infectious endocarditis
children: osteomyelitis
Dx of cardiomyopathy
intrinsic disease NOT associated with:
ischemic
valvular
hypertensive or
structural congenital heart disease
How pericarditis can be fatal
increased pericardial sac contents
tamponade
Hemopericardium etiologies
ruptured MI
retrograde aortic dissection
penetrating chest trauma
Atrial myxomas clinical sequelae
prolapse and obstruction of AV valves or systemic embolization
ARDS
adult respiratory distress syndrome
usually occurs in patients that are already critically ill
Normal ejection fraction
55-75%
Hemoglobin levels and angina
exisiting coronary artery disease can cause angina episodes when anemic
anemia –> even less O2 delivered to already poorly perfused arteries
Electromechanical dissocation
electrical activity present
no pulse present
(can be tampanade or aortic dissection)
((if aortic dissection, bleeds out the top and runs back down the side into pericaridal sac))
Most common cause of right heart failure
left heart failure
