Congestive Heart Failure
Assessment
Signs
Right-sided
pitting edema, JVP elevation, hepatomegaly, ascites
Congestive Heart Failure
Investigations
Labs
CBC, electrolytes, AST, ALT, BUN, Cr, Troponin, BNP (or NT-proBNP)
Congestive Heart Failure

Tests
CXR, ECG, PoCUS (systolic function, pulmonary edema)
Congestive Heart Failure
Management
General
ABCs, monitors, 100% O2 non-rebreather facemask, vitals, IV access, position upright, +/- Foley catheter, treat precipitating factor Morphine 1-2mg IV prn
Congestive Heart Failure
Management
First-line
Nitroglycerin 0.4mg sl q5min (if sBP>100) +/- topical nitroglycerin patch (0.2-0.8mg/h)
Furosemide: double home dose, 20mg IV if furosemide naive
Congestive Heart Failure
Management
Second-line
Double furosemide dose
Think Sympathetic Crashing Acute Pulmonary Edema (SCAPE):
Nitroglycerin infusion if hypertensive (start 100μg/min & titrate)
Think Cardiogenic Shock if hypotensive (sBP<90): Norepinephrine 2-
12μg/min or Dobutamine 2.5μg/kg/min
