Suspicion for CHF
1) Symptoms: Dyspnea, orthopnea, edema, chest pain
2) Exam: Vital Signs, Weight with comparison to dry weight, Jugular Venous Pressure, Presence of rales, Temperature of extremities, presence of S3 gallop
1) Labs:
a. Chem 7, LFTs, Coags, CBC b. NT-BNP, lactate if “cold”
c. If suspicious for acute coronary syndrome or new presentation of CHF – TnT, CPK, CK-MB 2) Chest X-ray
3) EKG Using guidance from the
Most Helpful Features in Making a Diagnosis o f CHF in The ER
, Is CHF the most likely diagnosis?
Consider alternate diagnosis
Initiate HF management:
1) Loop Diuretics (see aside) 2) Supplemental oxygen if O2<93%
3) Serial ECGs if suspicion for ACS
4) Vasodilators for hypertensive patients (see aside)
Loop Diuretic Dosing Guidelines:
1) If mild volume overload consider single bolus dose IV lasix protocol
2) If mild to moderate volume overload consider bolus and short infusion or overnight infusion
3) If moderate overload keep overnight for lasix infusion and assess response next day to decide on admission
4) If severe volume overload or consider overnight infusion for partial volume removal and serial outpatient visits for bolus dosing
Imminent respiratory failure anticipated or hemodynamic instability
- NIPPV
- ET intubation
- If hypertensive administer IV vasodilator e.g. nitroglycerine or nitroprusside
- If hypotensive, administer IV inotrope e.g. dopamine or levophed
- Call HF attending and plan for ICU admission
Perform history and physical exam and order laboratory and basic studies
No
Yes
What is your assessment of hemodynamic status using
the hemodynamic model?
Impaired Perfusion or “Cold”:
- Signs: Narrow pulse presure, elevated lactate, cool
extremities, altered mentation, AKI, elevated transaminases
- Discuss with HF attending on service regarding triage to cath lab, Farr 3 HF, or CCU and establish initial
management strategy while awaiting bed (including initiation of IV inotrope if indicated)
“Cold”
“Warm”
Vasodilator guidelines:
1) If BP > 160/90mmHg administer PO, SL, or topical vasodilator (e.g. ACE inhibitor, labetalol, SL NTG, Topical NTG) 2) If BP remains elevated or SBP
>180/100mmHg on arrival favor IV therapy (e.g. IV NTG (bridge to floor), IV NTP (CCU), IV labetalol (CCU)) 3) If patient has evidence of pulmonary
edema, favor use of primary venodilator (e.g. SL NTG, Topical NTG, or IV NTG).
4) Avoid Morphine Sulfate
Reassess after 1-2 hours
General Criteria for CDAc Management:
I. Stable hemodynamics (SBP>= 90mmHg on presentation) and respiratory status (RR<32 breaths/min, O2 sat > 90% on room air)
II. Creatinine < 3.0mg/dL and no change greater than 33% from baseline (this is guide, but with many HF patients having advanced CKD can be adjusted to individual patients)
III. Absence of new ST depressions on ECG or Troponin-T <0.10
IV. No significant co-morbidities requiring acute intervention
V. No signs of poor perfusion VI. Response to initial therapy No
CDAc Observation Management Protocol
Yes
1. Initial plan single bolus: Give double the previous dose of diuretic and start infusion with plan to keep overnight
2. Initial plan bolus and infusion:
Give double the previous bolus dose and increase infusion 50%
3. Add IV nitroglycerine
4. Consider alternative diagnosis
Reassess after 1-2 hours
Is This Patient Appropriate for CDAc management?
Admit to HF (see protocol for handoff to
Heart Failure Team)
Yes No
1. IMPROVING SYMPTOMS with urine output > 500-750cc?
2. SBP normalized (120-140mmHg)?
Administer dose of oral diuretics
Guidance on oral diuretic dose:
1. If lasix naïve give an equivalent dose to the IV dose needed to achieve adequate urine output (generally 20-40mg PO)
2. If on lasix at home and dietary or medication non-compliance to blame for decompensation give home dose
3. If it seems home lasix dose was insufficient or renal function has worsened double home dose
4. Same principles apply to torsemide except PO torsemide ≅ IV lasix so if patient is getting 40mg IV lasix then would transition to 20mg PO torsemide
What is the patient’s EF?
Check Chem 7 every 12 hours
Replete K to > 4.0 with PO KCL. If repletion is needed, patient should be discharged
on supplemental potassium chloride
Symptoms stabilized and
congestion improved after
IV diuretics?
Order TTE

Algorithm for patients with dep ressed EF (see additional notes below)
Notes on the above algorithm:
1. If patient on ACE-I or ARB at home and SBP >
140/90 despite treatment, uptitrate dose 2. If patient not on either ACE or BB and SBP
<140/90mmHg then start with ACE-I only, if patient is hypertensive then both can be started
3. Contraindications to ACE initiation should be documented
4. Metoprolol succinate is favored over metoprolol tartrate because of once daily dosing
