other cardio diseases Flashcards
(31 cards)
most common problem in coronary artery disease CAD
atherosclerosis
-sob, diaphoresis, n/v
pt taking cocaine and low supply/deman of O2 –> signifies
CAD
explain process in atherosclerosis
1) plt aggregates
2) smooth muscle cells migrate to intima and multiply
3) endothelial cells regenerate to recover (thickening)
4) plaque (thrombi)
5) rupture –> lead to MI
thromboxane A2, serotonin and endolial dysfxn can all cause a ___ in blood flow seen in _____ disease
decrease
-CAD
“stunned” myocardiyn
restorations after LONG periods of ischemia
persisting period of CP can lead to
IM
pt severe cp worse with inspiration is significant of
Pericarditis
to and fro rub with high pitch is indicative of
pericarditis
kussmal sign
increase of JVP with inspiration RAP too
*Pericarditis
calcium can lead to
scarring
diastolic knock
filling is normal but suddenly stops due to the stiffness in pericarditis
-makes v wave noticeable
seen in pericarditis
becks triad and where is it seen
-hypotension
-elevated JVP
-muffled heart sounds
——————
Pericardial Effusion and Tamponade
arteriole is to _____ pressure as venue is to _____ pressure seen in capillary occlusion
1) hydrostatic
2) oncotic
what is the most potent vasoconstrictor
endothelia-L1
most potent vasodilator
NOS
diff b/w BNP and ANP
bnp is in ventricles, and ANP is in atrium myocyte stretch
vasodilator vs vasoconstriction
- prostacyclin
- thromboxane
- NO
- endothelin
- norepi +epi
- kinins
- Natriuretics
vasoconstrictors:
thromboxane, endothelia, norepi + epi,
Vasodilators:
prostacyclin, NO, kinins, natriuretics,
c-reactive protein is a marker of
inflammation or plaques
oxidized LDLs inhibit
NO
chylomicron
protein coat of lipids
estrogen can remove ___ but also ___ blood clots
cholesterol; increase
homocysteine is seen in ____ and metabolized enzymes dependent on these 4 supplements
atherosclerosis ; B6, B12, folic acid
what is and where is homans syndrome is seen in
calf pain at dorsiflexion of foot; DVT
4 types of shock
hypovolumic
distributive
cardiogenic
obstructive
