Heart failure Flashcards
(80 cards)
Systolic heart failure
EF <40%
Diastolic HF
EF> OR = 50%
Diastolic dysfunction is present in both
HF with reduced ef and with perserved
1/2 of heart failure pts hvae what
normal EF> 50%
Women are more likely to be affected by heart failure with or without preserved EF
with preserved EF
In diastolic dysfunction heart failure, higher ______ filling pressures are required to achieve normal EDV
Left ventricle
_______ exacerbates diastolic dysfunction
Tachycardia
Even though pts with diastic dysfunction have a perserved ef, these pts often have what
exercise intolerance
What symptom is more common with heart failure reduce ejection fraction?
S3 gallop
Radiogrpahic evidence may lag behind clincal evidence by up to
12 hours
Most common diagnostic took to diagnose heart failure
Echocardiogram
_______ alone has a low predictive value for HF or risk prediction
EKG
What are the two imporatnt biomarkers in heart failure
BNP, N-terminal BNP
which class of NYHA heart failure is the least worse
class I
what class is the worse?
class IV
Are medication treatments effective for Heart failure with preserved EF?
No
Main three drugs for chronic heart failure with reduced EF
Beta blockers and ACE-Inhibitors, ARBS
The goal of surgical treatment of chronic heart failure is what
To prevent ventricular remodeling
What is used for HF with a ventricular conduction delay
Biventricular pacing
When is cardiac resynchronization therapy indicated?
Pts with an EF<35% and a QRS duration 120-150ms
What allows remote observation of intracardiac pressures to guide HF tx
CardioMEMS
What are used for prevention of sudden death in pts with advanced heart failure
ICD’s
What may be used in the terminal stages of HF or awaiting transplant
LV assist devices
Acute heart failure is described as what
rapid onset, presenting with life threatening conditions. Treatment is aimed at decreasing volume and stabilizing hemodynamics
