Definition of Heart Failure

Classification Ejection

Fraction Description

I. Heart Failure with

Reduced Ejection

Fraction (HFrEF)

≤40% Also referred to as systolic HF. Randomized clinical trials have

mainly enrolled patients with HFrEF and it is only in these

patients that efficacious therapies have been demonstrated to

date.

II. Heart Failure

with Preserved

Ejection Fraction

(HFpEF)

≥50% Also referred to as diastolic HF. Several different criteria have

been used to further define HFpEF. The diagnosis of HFpEF is

challenging because it is largely one of excluding other potential

noncardiac causes of symptoms suggestive of HF. To date,

efficacious therapies have not been identified.

a. HFpEF,

Borderline

41% - 49% These patients fall into a borderline or intermediate group. Their

characteristics, treatment patterns, and outcomes appear similar to

those of patient with HFpEF.

b. HFpEF

Improved

>40% It has been recognized that a subset of patients with HFpEF

previously had HFrEF. These patients with improvement or

recovery in EF may be clinically distinct from those with

persistently preserved or reduced EF. Further research is needed

to better characterize these patients. 5

Stages / Classification of Heart Failure

Sudden or gradual onset of the signs

and symptoms of heart failure requiring unplanned office visits, emergency room visits, or hospitalizations.

Associated with pulmonary and systemic congestion due to increased left and right heart filling pressures.

Rehospitalization rate predicted to be 50% at 6 months

1-year mortality of approximately 30% of ADHF admissions (ACCF/AHA 2013 HF Guidelines)

Acute Decompensated Heart Failure (ADHF)

9

Common Precipitating Factors of ADHF

Non adherence with Medications

Dietary sodium intake

Fluid intake

Acute MI

Arrhythmias Atrial fibrillation

Persistent hypertension

Recent addition of negative inotrope

Pulmonary embolism

Nonsteroidal anti-inflammatory drugs

Excessive alcohol or drug use

Endocrine abnormality

Concurrent infection

New anemia

10

ACS / coronary ischemia (troponins typically elevated

with ADHF)

Severe hypertension

Atrial or ventricular arrhythmias

Infections

Pulmonary emboli

Renal failure

Medical or dietary compliance

Valvular heart disease

New onset anemia

Potential Contributing

Precipitating Factors and/or Comorbidities

11

Evidence of severe ADHF, including:

Hypotension

Worsening renal function

Altered mentation

Dyspnea at rest

Typically reflected by resting tachypnea

Less commonly reflected by oxygen saturation <90%

Hemodynamically significant arrhythmia - including new onset of rapid atrial fibrillation

Acute coronary syndromes

Hospitalization Recommended

12

Worsened congestion: Even without dyspnea Signs and symptoms of pulmonary or systemic congestion Even in the absence of weight gain Major electrolyte disturbance Associated comorbid conditions Pneumonia Pulmonary embolus Diabetic ketoacidosis Symptoms suggestive of transient ischemic accident or

stroke Repeated ICD firings Previously undiagnosed HF with signs and symptoms of systemic or pulmonary congestion

Hospitalization Should be Considered

13

Improve symptoms, especially congestion and low-output symptoms

Optimize volume status

Identify etiology

Identify and address precipitating factors

Optimize chronic oral therapy

Minimize side effects

Identify patients who might benefit from revascularization

Identify patients who might benefit from device therapy

Identify risk of thromboembolism and need for anticoagulant therapy

Educate patients concerning medications and self management of HF

Consider and, where possible, initiate a disease management program

Treatment Goals

14

Based on signs and symptoms

B-type natriuretic peptide (BNP) or N-terminal pro-B-type natriuretic peptide (NT-proBNP)

Good to assess in patients with dyspnea being evaluated for HF

Should not be used as the sole tool to diagnose HF

Must be used in concert with signs and symptoms

Special consideration with renal insufficiency and obesity.

Diagnosis

15

Patient 1: Volume overload (Backwards Failure)

Patient 2: Profound depression of cardiac output –hypoperfusion (Forwards Failure)

Patient 3: Signs and symptoms of both fluid overload and hypoperfusion (cardiogenic shock)

Acute Decompensated Heart Failure

Reduce Afterload Arterial vasodilators High dose Nitroglycerin Nitroprusside Neseritide

Intra aortic balloon pump

Increase Contractility Positive Inotropes

Dobutamine

Milronone

Dopamine

Reduce Preload Diuretics Venous Vasodilators Low dose NTG Neseritide

Ultrafiltration

26

Pharmacological Options for Decreasing

Preload

Stop or decrease fluid

Diuretics ▪ A loop diuretic such as furosemide eliminates

circulating volume

Venous

Vasodilators

▪ Intravenous nitroglycerin, neseritide, or

morphine sulfate

(Venous vasodilatation pools blood away from

the heart and decreases preload)

ACE Inhibitors or

Angiotensin II

Receptor Blockers

(ARBs)

▪ Interrupt renin- Angiotensin- aldosterone system. (RAAS).

Aldosterone secretion is decreased and there is less sodium and

water retention.

▪ ACE inhibitors end in “pril” / ARBs end in “sartan”

Aldosterone

antagonists

▪ Spironolactone or epleranone

▪ Directly block aldosterone and there is decreased sodium and water

retention.

IV not PO Early intervention - ED

Dose high enough to relieve signs and symptoms of congestion Should equal or exceed chronic oral dose

Caution for signs of over diuresis Hypotension: check orthostatics

Worsening renal failure

Monitor e-lytes (potassium, magnesium, sodium) Arrhythmias

Muscle cramps

Monitor for gout

Frequent reassessment

Reduce Preload Loop Diuretics

27

Diuretics and Renal Function

Role of venous congestion in worsening renal function

Role of volume depletion / hypotension and worsening renal function

28

Moderate to severe renal dysfunction with fluid

overload

Continue to treat with diuretics

In severe fluid overload renal dysfunction my improve with continued treatment

May need to hold ACE I secondary to AKI

Venous congestion plays a role in worsening renal function (not just hypoperfusion)

Cardiorenal Syndrome

Loop Diuretics

Bumetanide (Bumex) Equivalents Furosemide 40 mg Torsemide 20 mg Bumetanide 1 mg

Dosing

Torsemide (Demadex)

More on Loop Diuretics

31

DOSE Trial NEJM: Felker et al., 2011

No significant difference in symptoms or renal function between continuous drip versus intermittent dosing

Non significant trend toward improvement in symptoms with high dose (IV at 2.5 x PO dose)

versus low dose; (IV at same as PO dose) no change in renal function

Bumetanide Furosemide Torsemide

Lack of randomized control data with comparison to furosemide. Better pharmacokinetic profile (oral bioavailability) than furosemide but turosemide has evidence of more efficacy and more safety. (Wargo &Banta, 2009)

BID Dosing when GFR is low

2 randomized trials comparing Torsemide and Furosemide N=471 Torsemide associated with reduction in HF and CV readmission in systolic HF with a trend towards reduction of all cause mortality. (DiNicolantonio, 2012)

34

Nitroglycerin

35

Uses: Acute MI, unstable angina, CHF

Side Effects:

H/A, Hypotension, flushing

Nursing Considerations: Contraindicated with

Sildenefil like drugs Caution (all venous

vasodilators) with: Hypertrophic

cardiomyopathy, aortic stenosis, right ventricular MI

Treat H/A with pain meds

and decrease dose

Onset IV: 1-2 minutes Duration: 3-5 minutes

Nesiritide (Natrecor)

Recombinant form of human B type natriuretic peptide (BNP)

BNP is a naturally occurring cardiac neurohormone secreted by the heart in the body’s response to heart failure

BNP allows the heart to participate in the regulation of vascular tone and extracellular volume status

The BNP system and the renin-angiotensin system counteract each other in heart failure

BNP levels are elevated in heart failure

36

Nesiritide (Natrecor)

Balanced arterial and venous vasodilatation Causes rapid

reduction in right and left sided ventricular filling pressures (preload reduction)

Reduces afterload

Indicated for acutely decompensated heart failure patients who have dyspnea at rest

37

Nesiritide (Natrecor)

Patient must have systolic BP > 90 mmHg

PAOP should be estimated to be > 20 mmHg

Given by IV bolus and maintenance infusion (bolus to be taken from reconstituted IV bag and not from vial)

Infusion is usually 24-48 hours

38

Monitor BP closely during administration.

Nesiritide: Where do we stand?

39

Balanced venous and arterial vasodilator

Sackner-Bernstein JD, Kowalski M, Fox M, Aaronson K: Short-term risk of death after treatment with nesiritide for decompensated heart failure: a pooled analysis of randomized controlled trials. JAMA 2005, 293:1900-1905.

In the 3 trials, 485 patients were randomized to nesiritide and 377 to control therapy. Death within 30 days tended to occur more often among patients randomized to nesiritide therapy (35 [7.2%] of 485 vs 15 [4.0%] of 377 patients. No statistically significant difference.

ASCEND HF Trial

Effect of Nesiritide in Patients with Acute Decompensated Heart Failure

O'Connor et al.

July 7 2011

7,141 patients

Randomized

Nesiritide was not associated with an increase or a decrease in the rate of death and re-hospitalization.

It was not associated with a worsening of renal function, but it was associated with an increase in rates of hypotension.

Neseritide cannot be recommended for routine use.

Nitroprusside

Mixed venous and arterial dilator (primarily arterial)

Decreases BP, SVR, PVR, PAOP, RAP

Uses: Hypertensive crisis

CHF

Acute Mitral Regurgitation

Other Indications for Afterload Reduction

Side Effects: Hypotension Thiocyanate toxicity:

tinnitus, blurred vision, delirium, seizures, muscle twitching, absent reflexes, dilated pupils [several days – high doses]

Nursing Considerations: Onset: 1-2 minutes Duration: 1-10 minutes Monitor BP carefully-

arterial line encouraged

41

Persistent failure with aggressive diuresis and standard oral therapies NTG

Neseritide

Nitroprusside Especially helpful with severe hypertension or severe

MR

For rapid symptom relief in acute pulmonary edema with hypertension NTG / Nitroprusside

Do not give with hypotension

Reduce Preload Venous Vasodilators

42

If No Improvement With Preload Reduction

Na and fluid restrict Increase dose of loop

loop diuretic Add 2nd diuretic PO Maximize loop diuretic Metalazone Spironolactone

OR IV chlorothiazide

Consider ultrafiltration

Diuretic Resistance

Reasons

High sodium levels

NSAIDs

Severe renal impairment

Renal hypoperfusion

43

Ultrafiltration

UNLOAD Trial Veno-venus ultrafiltration

(UF) vs standard IV diuretic therapy for hypervolemic HF

200 patients randomized UF with statistical

significance for: greater weight loss (48 hours), greater fluid loss (48 hours), less 90-day resource utilization for HF.

No statistically significant difference in dyspnea scores or creatinine levels (safety endpoint)

CARESS-HF Trial Treatment of ADHF,

worsening renal function, persistent congestion with stepped pharmacologic approach vs ultrafiltration

188 patients randomized

UF: inferior to pharmacologic therapy and associated with adverse events.

44

Goal: Relief of symptoms and end organ perfusion

Use in:

Low output states

Symptomatic hypotension or marginal blood pressure Despite good filling pressures

No magic blood pressure – look for symptoms

Unresponsive / intolerant of IV vasodilators

Diminished or worsening renal function

Use vasodilators first as able

Monitor closely for tachyarrhythmias and hypotension

Not recommended if normotensive (ACC)

Increase Contractility Inotropes

45

46

Dobutamine

What receptors are stimulated:

Primarily β1

Some alpha1 receptor stimulation

Some β2 stimulation

Modest β2 (more β2 than alpha1)

What are the resultant actions:

Increase contractility (+ inotrope) (β1)

Increase AV node conduction

Modest vasodilation

When and why do we use: Used as an inotrope (resultant preload reduction) with modest afterload reduction

(ACC / AHA Guidelines for Heart Failure*)

What are special nursing considerations:

Onset 1 to 2 minutes; Peak 10 minutes

Half-life 2 minutes

Note: Blood pressure response is variable; β2 causes vasodilatation; β1 increases cardiac output and may increase BP

Milrinone (Primacor)

Creates + inotropic effect by increasing availability of calcium Inhibits the degradation

of cyclic AMP which is indirectly responsible for increasing the influx of calcium through the calcium channel

Smooth muscle relaxant (venous and arterial vasodilator)

Indications: Refractory heart failure

(in combination with dobutamine)

Left ventricular failure in MI

Patients waiting transplant

Side Effects: Ventricular arrhythmias,

thrombocytopenia (new generation less)

OPTIME Trial

48

OPTIME Trial Milrinone approved by FDA based on hemodynamic data Future trials need to include symptom relief and post

discharge outcome data OPTIME Prospective trial, randomized, placebo controlled 951 patients Patients had indication for but not all required inotrope for end

organ perfusion. Results: No difference in LOS, No difference in subjective

improvement Treatment failures more common in milrinone group due to

hypotension, more atrial fibrillation in milrinone Not powered for mortality differences

Conclusion: Hemodynamic improvement does not translate into clinical improvement

49

Dopamine

What receptors are stimulated:

Dopaminergic at low doses (0.5-2.0 mcg/kg/min)

β1 also at moderate doses ( 2.0-10.0 mcg/kg/min)

Pure alpha stimulation at high doses > 10mcg/kg/min

What are the resultant actions:

Increase GFR at low doses

Increase contractility at moderate doses (greater effects on contractility than heart rate)

Vasoconstriction (alpha) at high doses

When and why do we use:

Refractory hypotension / shock

* Not indicated for routine treatment or prevention of acute renal failure

What are special nursing considerations:

Onset 1-2 minutes; Peak 10 minutes

Maximal effects @20/mcg/kg/min

Large IV line or central line; Regitine (alpha blocker) for infiltrate

Volume status and cardiac filling pressures are unclear

Pulmonary and systemic pressures unclear

Clinically significant hypotension (SBP < 80 mm Hg)

Worsening renal function

Invasive Monitoring

55

Foley Catheter

56

Dietary Sodium Restriction Water follows sodium

If hyponatremic Serum sodium < 130 mEq/L

2 liters per day

Serum Sodium < 125 mEq/L

Stricter fluid restriction may be considered

If persistent fluid overload Assure sodium restriction in conjunction with fluid

restriction
