Congestive Heart Failure Flashcards
CHF
causes
10
- MI
- arrhythmias
- uncontrolled HTN
- dietary/med noncompliance
- substance abuse
- anemia
- hyper thyroidism
- AKI
- PE
- sepsis
CHF
what is it?
sx of hypervolemia due to impaired cardiac function (decreased filling/decreased squeezing)
CHF
normal EF
55-65%
CHF
what do you need to differentiate? how do you do it?
- HFpEF vs HFrEF
- echo
CHF
describe Stage A
pateitns at risk for CHF but without sx, structural changes, or elevated biomarkers
CHF
describe Stage B
patients without current sympoms of CHF, but has one of the following:
* structural heart disease
* abnormal cardiac function
* elevated cardiac biomarkers
CHF
describe stage C
patients with current or prior symptoms and/or structural changes and/or elevated cardiac biomarkers
CHF
describe Stage D
severe sx at rest, recurrent hospitalizations despite GDMT, intolerant to GDMT, requires advanced therapies (transplant, mechanical circulation), palliative care
CHF
a pt present with new dx of CHF. Echo shows EF is 55%. What is the best documentation?
acute HFpEF
CHF
presentation of right sided
3
- pedal edema
- abdominal bloating
- nausea/decreased appetite
CHF
presentation of left sided
4
- DOE/SOB
- orthopnea
- cough
- decreased exercise tolerance
CHF
Physical Exam Findings of Right Sided
6
- distended neck veins (JVP > 8cm)
- abd distension
- pedal edema (1-4+)
- hepatojugular reflux
- ascites
- liver enlargement/tenderness
CHF
PE findings of left sided
3
- rales/crackles/wheezes
- dullness to percussion
- S3, S4, or gallop
signs/sx of low perfusion
6

- low sodium
- cool extremities
- hypotension on ACE
- renal/hepatic dysfunction
signs/sx of congestion
6
- orthopnea/PND
- JVP distension
- hepatomegaly
- edema

CHF
Lab work up
4
- BMP or CMP
- BNP or pro-BNP
- TSH
- CBC
CHF
diagnostic work up
3
- echo
- EKG
- CXR
CHF
what can falsely lower BNP?
obesity or CKD
CHF
what can falsely elevate BNP?
ARNI (entresto)
CHF
EKG findings?
4
- LVH
- afib or atrial flutter
- LBBB
- Q waves (old MI?)
CHF
CXR findings
ABBCDEE
- Alveolar edema
- Blunting of margins
- Kerley B lines
- Cardiomegaly
- Dilated upper lobe vessels
- Pleural effusion
- PE
CHF
how to navigate CHF?
4 components
- Dx (echo, BNP, then stage)
- work up (reversible?, est baseline tests)
- Treat sx
- follow up
CHF
4 components of tx
- symptom relief
- tx of underlying disorders
- education
- Rx: fantastic 4
CHF
what are the fantastic 4 meds?
- BB
- ARNI/ACE/ARB
- Spironolactone
- SGLT-2 Inhibitor
CHF
which meds provide sx relief?
loop diuretics
CHF
what education can be provided?
- low sodium diet
- 2L fluid restriction
- exercise
- optimal BMI
- med compliance
- watch for warning sx
CHF
tx of HFpEF with LVEF < 50%
- Diuretics PRN
- SGLT2
- ARNI
- MRA
- ARB
CHF
heart failure tx goals

- HR: < 70 bpm
- Euvolemic (warm + dry)
CHF
tx of HfmrEF

- canagliflozin
CHF
which ARNI?
- entresto
CHF
which MRAs?
2
- Spironolactone
- Eplerenone ($$)
CHF
which BB should be avoided in CHF?
atenolol
CHF
which BB are most rec for CHF?
- carvedilol
- metoprolol
CHF
drugs to avoid if EF < 40%
- NSAIDs or COX-2 inhibitors
- CCBs: diltiazem, verapamil
- ACE/ARNI/ARB combos
- thiazolidinediones (pioglitazone, rosiglitazone)
- sulfonylureas
CHF
what does “ I NEED HELP” stand for for CHF tx
- I: intravenous inotropes
- N: NYHA calss IIIB to IV or persistently elevated natriuretic peptides
- E: end organ dysfunction
- E: EF < 35%
- D: defibrillation
- H: hospitalizations > 1
- E: edema despite escalating diuretics
- L: low systolic BP (< 90), high HR
- P: prognostic medication; progressive tolerance or down-tiltration of GDMT
