Cardiology Flashcards
Mitral regurg will manifest as
increase in LV volume and pressure
Order of aortic and pulmonic valves
A2 P2
Any one of the following meets dx of MI
Rise or fall in biomarkers with ONE of the following
- ischemia
- Q waves
- ST or T changes
- LBBB
- intracoronary thrombus
- loss of viable myocardium
if cardiac biomarkers are initially neg..
remeasure within 8-12 hours after Sx
T/F degree of + trops is important for prog
TRUE
T/F CArdiac biomarkers are not needed with pt ischemic chest pain and st elevation
TRUE
first biomarker to increase
second?
When do trops peak?
Myoglobin and CK isoforms
Trop (peaks 1-2 days) - elevated to 2 weeks
Creatine Kinase
peak? for how long?
CKMB - found in heart
increase within 3-12 hours of onset
peak at 24 hours
baseline 48-72 hours
Where are ANP and BNP secreted
BNP - ventricles
ANP - cells of atria
What is increased if vent cells have high pressure and volume?
ANP and BNP
ANP and BNP have __ effects. which is more sensitive to LV?
diuretic, natriuretic, hypotensive, BNP - duh
BNP interpretation
> 400 pg/mL = HF
NT-pro BNP cut off by age
75
75 = 1800
Mg def associated with 4 things
multifocal cellular necrosis
increased platelet aggregation
atherogenesis
card arrhym
if Stable Angina presents with _______, send to PCI or CABG
severe sx change in Sx severity failed med tx high risk coronary anatomy worsening LV fxn
Indication for CABG
L main CA stenosis
Stenosis of prox LAD and Prox cirumflex
___________in ASx/mild/stable angina
_____________in pt with low LV fxn
___________and large area of viable myocardium in high risk area in stable angina
______prox LAD stenosis with EF ______or dem ischemia
L main CA stenosis = 50%
Stenosis of prox LAD and Prox cirumflex = 70%
3 vessel dz in ASx/mild/stable angina
3 vessel and with prox LAD in pt with low LV fxn
1-2 vessel dz and large area of viable myocardium in high risk area in stable angina
>70% prox LAD stenosis with EF
LVEF normal = below normal = may confirm HF = risk for life threatning irreg beats =
normal = 55-70%
below normal = 40-55%
may confirm HF =
cardiac tamponode triad
JVD, muffled heart sounds, hypotension
Pt with unstable angina and Sx in office =
send to ED
_____ and ____ are most likely to have odd Sx
elderly and diabetics
