Heart Failure Flashcards
Which stages of ACC/AHA are considered “at risk” for heart failure?
Which stages are considered “heart failure”
at risk = stage A and B
heart failure = stage C and D
What physical findings are associated with pulmonary congestion associated with left heart failure
pulmonary edema cough with frothy pink sputum cyanosis orthopnea PND
You’re doing a physical exam on someone who has acute heart failure. What do you see/hear/feel?
(7 things)
- Edema
- JVD
- Crackles at bases
- displaced PMI
- S3/S4 gallop
- hepatomegaly
- hepatojugular reflex
What is a reasonable response for the edema to diminish in a patient who started furosemide (Lasix)
1kg/day weight loss
goals of therapy:
reducing afterload will have what desired effect
improve cardiac function
What labs do you order when evaluating for heart failure?
- cardiac enzyme to rule out acute ischemia
- CBC
- CMP
- Brain-type natriuretic peptide (BNP)
(THESE ARE THE MAIN FOUR)
others : UA, lipid, thyroid, iron
Which stage of NYHA classification
ordinary physical activity does not cause breathlessness, fatigue, or palpitations
Stage 1
Which stage of NYHA classification
ordinary physical activity results in undue breathlessness, fatigue, or palpitations
Stage 2
A patient with suspected heart failure should get what diagnostic tests? (3)
- EKG
- echo
- Chest x-ray
Which diagnostic exam is the most useful in determining heart failure
echo
the most common type of heart failure is
left ventricular systolic dysfunction
A patient with a Brain-type natriuretic peptide (BNP) less than 100 has a ________ prognosis
A patient with a Brain-type natriuretic peptide (BNP) greater than 400 has a ______ prognosis
good
poor
If a patient has a Brain-type natriuretic peptide (BNP) less than 100, what can you rule out?
heart failure
What is important to remember about starting a patient on ACE inhibitors for the first time?
titrate to maximum/target dose
monitor for hyperkalemia
they may get a cough
NYHA classification is based on
limitations of activity
Which type of heart failure is associated with reduced ejection fraction? (less than 40%)
systolic/ HFrEF
What are the four findings on a chest x-ray that are suggestive of heart failure
- cardiomegaly
- cephalization of pulmonary vessels (more prominent at the apex of the lungs to compensate for fluid filled base)
- Kerley-B lines (interstitial edema)
- Pleural effusions
cardiomegaly is a cardiac to thoracic ratio of:
greater than 50%
What are the four basic principles of treatment of heart failure
- manage underlying cause
- manage precipitating cause
- control symptoms of failure
- review medications
right heart failure is due to a ____ pressure, _____ compliance system
low pressure, high compliance system
the most common cause of heart failure (either side)
coronary artery disease
Which stage of NYHA classification
breathlessness, fatigue, or palpitations at rest
Stage 4
What is the most common cause of right heart failure
left heart failure
What physical findings are associated with congestion of peripheral tissues associated with right heart failure
peripheral edema
RUQ pain
JVD
ascites
acute heart failure most important symptoms
- DYSPNEA (DOE–> orthopnea –> PND–> dyspnea at rest)
- fatigue/weakness
- dependent edema
- weight gain (10/12 lbs in A DAY)
- cough- nocturnal, nonproductive
Which type of diuretics do you give to HF patients
loop
pathophysiology of left heart failure is characterized by elevated ______
left ventricular filling pressures
What is significant about left ventricular compliance with HFpEF
decreased compliance - inability to relax
structural heart disease + asymptomatic is what stage of the ACC/AHA
Stage B
In HFrEF, what is different about the left ventricular volume?
increased
Which type of heart failure is associated with volume overload
HFrEF / systolic
HFrEF is what kind of dysfunction + symptoms of heart failure?
systolic
