Congestive Heart Failure Flashcards
CO=
SV x HR
SV comprised of what?
contractility, preload, afterload
MAP=
2/3 diastolic + 1/3 systolic
nesiritide MOA?
mimic ANP ausing natiuresis
PE of CHF?
S3, S4, RV heave, cheyne stokes breathing
BNP in obesity?
decreased
BNP in renal failure, elderly, sepsis?
increased
cardiomems, who is it for, whats the benefit?
NYHA class III, reduce CHF hospitalizations, improves QOL
Pagets disease mechanism of heart failure?
high output heart failure from AVM within bones
tx for pagets disease?
bisphophinates
who gets an ICD with CHF?
NYHA class III, EF <35%, 40 days after event
who gets CRT/BVD in CHF?
EF <35%, NYHA III IV, widened QRS
mortality improvements in CHF?
eplerenone, CRT, valsartan sacubitril
valsartan sacubitril compared with ACE?
VS >ACE
who gets eplerenone/aldactone?
aldosterone antagonist, <40% EF
when to use mineralocorticoid antagonist (eplerenone or spironolactone) in MI?
mortality benefit in people post MI with CHF and EF <40%
positive pressure effect on both preload and afterload?
decreases both
preload- dec venous return
afterload- dec ventricular radius
meds best capable of remodeling LV?
ARB>CCB>ACE>BB
CXR findings in CHF?
effusion, cardiomegaly, redistribution of blood flow to the upper lobes
