Diagnosis of HF
I IIa IIb III
The diagnosis of heart failure is primarily based on signs and
symptoms derived from a thorough history and physical exam.
Clinicians should determine the following:
New
a. adequacy of systemic perfusion;
b. volume status;
c. the contribution of precipitating factors and/or comorbidities
d. if the heart failure is new onset or an exacerbation
of chronic disease; and
e. whether it is associated with preserved, normal, or reduced
I IIa IIb III
ejection fraction.
Chest radiographs, echocardiogram, and echocardiography are key
tests in this assessment.

• acute coronary syndromes/coronary
ischemia
• severe hypertension
• atrial and ventricular arrhythmias
• infections
• pulmonary emboli
• renal failure
• medical or dietary noncompliance
The Hospitalized Patient
I IIa IIb III
I IIa IIb III
Patients Being Evaluated for Dyspnea
Concentrations of BNP or NT-proBNP should be
measured in patients being evaluated for dyspnea in
which the contribution of HF is not known. Final
diagnosis requires interpreting these results in the
context of all available clinical data and ought not to
be considered a stand-alone test.
New
Acute coronary syndrome precipitating HF
hospitalization should be promptly identified by
electrocardiogram and cardiac troponin testing,
and treated, as appropriate to the overall
New
condition and prognosis of the patient.

The Hospitalized Patient
Treatment With Intravenous Loop Diuretics
Patients admitted with HF and with evidence of significant
I IIa IIb III fluid overload should be treated with intravenous loop
diuretics. Therapy should begin in the emergency department
or outpatient clinic without delay, as early intervention may be
associated with better outcomes for patients hospitalized with
decompensated HF (Level of Evidence: B).
If patients are already receiving loop diuretic therapy, the
I IIa IIb III initial intravenous dose should equal or exceed their chronic
oral daily dose. Urine output and signs and symptoms of
congestion should be serially assessed, and diuretic dose
should be titrated accordingly to relieve symptoms and to
reduce extracellular fluid volume excess. (Level of Evidence:
C).

The Hospitalized Patient
I IIa IIb III
Intensifying the Diuretic Regimen
When diuresis is inadequate to relieve congestion, as
evidence by clinical evaluation, the diuretic regimen
should be intensified using either:
New
a. higher doses of loop diuretics;
b. addition of a second diuretic (such as
metolazone, spironolactone or intravenous
chlorthiazide) or
c. Continuous infusion of a loop diuretic.
The Hospitalized Patient
I IIa IIb III
Ultrafiltration and Intravenous Inoptropic Drugs
Ultrafiltration is reasonable for patients with
refractory congestion not responding to medical
therapy.
New
I IIa IIb III
Intravenous inotropic drugs such as dopamine,
dobutamine or milrinone might be reasonable for
those patients presenting with documented severe
systolic dysfunction, low blood pressure and
evidence of low cardiac output, with or without
congestion, to maintain systemic perfusion and
preserve end-organ performance.
New
The Hospitalized Patient
Monitoring and Measuring Fluid Intake and Output
I IIa IIb III
Effect of HF treatment should be monitored
with careful measurement of fluid intake and
output; vital signs; body weight, determined at
the same time each day; clinical signs (supine
and standing) and symptoms of systemic
perfusion and congestion. Daily serum
electrolytes, urea nitrogen, and creatinine
concentrations should be measured during the
use of intravenous diuretics or active titration
of HF medications.
New
Diuretic Strategies in Patients with Acute
Decompensated
Heart Failure
A. Bolus dosing more effective
B. Continuous infusion more effective
C. Higher dose more effective than lower dose
D. Both B and C are correct
Diuretic Strategies in Patients with
Acute Decompensated Heart Failure
In a prospective, double-blind, randomized trial, we assigned 308
patients with acute decompensated heart failure to receive
furosemide administered intravenously by means of either a
bolus every 12 hours or continuous infusion and at either a low
dose (equivalent to the patient’s previous oral dose) or a high
dose (2.5 times the previous oral dose). The protocol allowed
specified dose adjustments after 48 hours. The co-primary end
points were patients’ global assessment of symptoms, quantified
as the area under the curve (AUC) of the score on a visualanalogue scale over the course of 72 hours, and the change in
the serum creatinine level from baseline to 72 hours.

I IIa IIb III
In all patients hospitalized with HF, both with
preserved and low ejection fraction, transition
should be made from intravenous to oral
diuretic therapy with careful attention to oral
diuretic dosing and monitoring of electrolytes.

Inotropic Support in Acute Heart
Failure


In the presence of significant hypotension,
dopamine may enhance both blood pressure
and peripheral organ perfusion.
Dopamine, in pressor doses (greater than 5
mcg/kg/min), increases myocardial oxygen
demand and potentially limits augmentation
of peripheral perfusion via peripheral
vasoconstriction

standard therapies, and
New
a. whose fluid status, perfusion, or systemic or
pulmonary vascular resistances are uncertain;
b. whose systolic pressure remains low, pr is
associated with symptoms, despite initial
therapy;

d. who require parenteral vasoactive agents; or
e. who may need consideration for advanced device
therapy or transplantation.

Routine use of invasive hemodynamic
monitoring in normotensive patients with
acute decompensated HF and congestion
with symptomatic response to diuretics and
vasodilators is not recommended.
New
Vasodilator Support in Acute
Heart Failure
Nitroglycerin, nitroprusside, and
nesiritide, have been demonstrated to
improve symptoms and hemodynamics in
acute heart failure.
Vasodilator Support in Acute
Heart Failure


Nitroprusside infusions (initial dose 0.1
mcg/kg/min) improve symptoms of
pulmonary congestion, and signs of
peripheral perfusion.
Titration of infusion rate is initailly
based on invasive hemodynamic
monitoring.
Vasodilator Support in Acute
Heart Failure

Nitroprusside patient variables:
– Chronic liver disease
– Renal insufficiency
– Blood pressure
– Malnourished patients
Vasodilator Support in Acute
Heart Failure

Nitroprusside toxicities:
– Cyanide intoxication: metabolic acidosis
– Thiocyanate toxicity: Hyper-reflexia,
seizures, altered mental status. Serum
concentration assay available
Vasodilator Support in Acute
Heart Failure


Nitroglycerin infusion may be
preferred in patients an active or
recent history of ischemia.
Nitroglycerin is a less potent arteriolar
dilator than nitroprusside
Vasodilator Support in Acute
Heart Failure






Nesiritide is a brain naturetic peptide (BNP) which
has significant vasodilator effects.
Dosing regimen, 0.2 mcg/kg bolus followed by 0.01

omecamtiv mecarbil or placebo and designed to evaluate the safety,
pharmacokinetics, pharmacodynamics, and potential efficacy of
omecamtiv mecarbil in patients with AHF
– The primary efficacy endpoint of dyspnea symptom response was not
met; favorable trends between the dose and plasma concentration of
omecamtiv mecarbil and dyspnea response. The incidence of worsening
heart failure within seven days of initiating treatment appeared lower in
each of the cohorts on omecamtiv mecarbil. Rates of adverse events
(AEs), serious AEs, adjudicated deaths and hospitalizations were similar
between omecamtiv mecarbil and placebo groups. Omecamtiv mecarbil
was not associated with an increased incidence of tachyarrhythmias nor

Improvement of Guideline Beta-Blocker Prescribing in
Heart Failure: A Cluster-Randomized Pragmatic Trial
of a Pharmacy Intervention
We conducted a pragmatic cluster-randomized trial, where facilities (n 5
12) with patients (n 5 220) were the clusters. Eligible patients had a
beta-blocker prescription that was not guideline concordant. Level 1
intervention included information to a pharmacist on facility guideline
concordance. Level 2 also provided a list of patients not meeting
guideline goals. Intervention and follow-up periods were each 6 months.
Achievement of full concordance with recommendations was low
(4%e5%) in both groups, primarily due to lack of tolerability. However,
compared with level 1, the level 2 intervention was associated with 1.9fold greater odds of improvement in prescribing (95% confidence
interval [CI] 1.1e3.2). Level 2 patients also had greater odds of a higher
dose (1.9, 95% CI 1.1e3.3). The intervention was aided by the patient
lists provided, the electronic medical record system, and staff support.
