CHF: Systolic Dysfunction Flashcards
In CHF staging, can you move up and down?
just up
NYHA Classification
I- cardiac dz without sxs II- fatigue/palpitations/dyspnea w/ ordinary activity IIIa- less than ordinary activity sxs IIIb- minimal activity sxs IV- rest pain
Describe the CHF staging system
Stage A- high risk for HF. no actual HF.
Stage B- structural dz
Stage C- structural dz + sxs ever
Stage D- refractory HF needing special intervention
do BB prevent recurrent MI for patients with HF?
yes
what is BNP NOT meant to be?
what are BNP/NT-BNP affected by (x3)
a screening tool
age, renal function (inc.), obesity (dec.)
> ? BNP in ED has a PPV of 90%?
500
<? BNP in ED has NPV of 90%?
100
is a CXR recommended for all HF patients?
yes
name two variables that are strong predictors of mortality/survival on a CPET (cardiopulm exercise test)
VO2
VE/VCO2
routine Bx in HF is not recommended. Name 3 cases where it is recommended.
rapidly progressive HF despite med Rx
suspect infiltrative process
malignant arrhythmias out of proportion to LV dysfxn (r/o giant cell myocarditis, sarcoid)
in pt’s with CHF< at what EF do you start an ACEI?
<40%
What did SOLVD trial show in HF?
enalapril lowers mortality and hospitalizations c/w placebo
3 BB that decrease mortality
carvedilol
metoprolol succinate
bisprolol
when would you start carvedilol for HF? Toprol XL?
carvedilol- high BP, DM/IGT
metoprolol succinate- marginal BP, causes less bronchospasm
RALES showed what?
mortality benefit with spirinolactone in pt’s with Class III or IV HF already on ACE/BB.
