alert threshold set up for "Mean Pressure above 20.0 mmHg". The reading
was taken on 25 Jan 04:06 EST.
Systolic: 89
Diastolic: 51
Mean: 66
Heart Rate: 91
Pressure waveform is attached.
Thank you,

Diuretics for ADHF and Fluid Overload
• Treatment with IV loop diuretics should begin
•
•
in the ED without delay, as early intervention
may be associated with better outcomes (Level
of evidence B).
If patients are already receiving loop diuretics,
initial IV dose should equal or exceed chronic
oral dose (Level of evidence C).
When a patient with congestion fails to
respond to IV diuretics, consider increased
dose of loop diuretic, addition of second
diuretic, continuous infusion of loop diuretic
(Level of evidence C)

Cardiorenal Syndrome: Worsening Renal
Function During Treatment of ADHF
•
•
•
Increase in creatinine ≥ 0.3 mg/dl
Occurs in 15-30% of admissions
Risk factors:
– Older age
– HTN, DM
– Baseline renal dysfunction
•
May be associated with adverse outcomes during
the hospitalization and post-discharge

Ultrafiltration:
An Attractive Alternative to Diuretics
•
More effective way to restore sodium balance1
– removal of isotonic vs. hypotonic saline
•
•
•
•
No effect on serum electrolytes
Rapid and predictable fluid removal
Does not stimulate neurohormones
May restore diuretic responsiveness and
improve long-term outcomes2

UNLOAD (sponsor-initiated)
– Greater weight loss at 48 hours
compared to IV diuretics (5 vs.

Options for Diuretic Resistant Patients
•
Vasodilators
– IV Nitroprusside, nitroglycerin
– Hydralazine/nitrates
•
Positive inotropes
– Dobutamine
– Milrinone
– Dopamine (renal-dose vs. higher doses)
•
Mechanical circulatory support

ADHF is a Good Time to Address
Risks and Co-Morbidities
•
•
•
•
Arrhythmias or conduction disease
– consider ICD for primary prevention
– AF: consider amiodarone/CV, ablation
– LBBB: consider CRT*
Risk of thromboembolism: need for
anticoagulation or anti-platelet therapy
Anemia, diabetes, obesity, sleep apnea
Advanced directives
*should NOT be used as a “bail-out”
Dying with HF is Rarely Unexpected

Within 6 months of death:

– 74% hospitalized at least once
– mean Na 128, Cre 3.1, Hct 30
