What is Heart Failure?
• Heart failure is a condition that develops when the heart's muscle becomes weakened after it is injured, often from a heart attack or high blood pressure, and fails to pump enough blood to meet the metabolic needs of the body.

Heart Failure Does NOT Mean...
• That the heart has stopped working or is about to stop working, or that the patient has had a heart attack.

How Does Heart Failure Affect the Body?
• Not enough blood circulating
• “Congestion” or fluid build up in the lungs, extremities, and other areas of the body

How Many People Have Heart Failure?
• Heart failure is very common
• Heart failure affects nearly 5 million Americans
• An estimated 400,000 to 700,000 new cases are diagnosed each year

Diagnostic Workup for Heart Failure
The following tests are helpful in diagnosing heart failure:
• Echocardiogram, or “ECHO” Ejection Fraction
Healthy heart = 60% or more
Heart failure = 40 % or less
• Electrocardiogram
• Chest X-ray

New York Heart Association (NYHA) Classification
• Class I - No limitation of physical activity
• Class I - Slight limitation of physical activity
• Class III - Marked limitation of physical activity
• Class IV - Unable to carry on any physical activity without discomfort

Is There a Cure For Heart Failure?
• No, currently there is no medical cure
• BUT, early diagnosis and proper treatment can:
- Significantly slow the progression of disease
- Keep patients out of the hospital
- Save lives!

What Are The Treatments for Heart Failure?
Experts recommend:
• Diuretics - helps control symptoms
• Digoxin - helps control symptoms
• ACE Inhibitors - can slow down disease progression
• Beta Blockers - can slow down disease progression
• Spironolactone - can slow down disease progression
This combination of medications has been proven to save lives and keep people out of the hospital.

Medicines to Control Symptoms...
• Diuretics: decrease fluid retention and reduce swelling
• Digoxin: improves blood circulation by strengthening the contraction of the heart

Medicines That Save Lives…used for their neuro-hormonal effects
• ACE Inhibitors: dilate or widen blood vessels; increase blood flow and block the body’s response to substances which can damage the heart
• Beta blockers: help strengthen the heart’s pumping ability; block the body’s response to substances which can damage the heart

Medicines That Save Lives…
• Spironolactone- for class III-IV heart failure patients. Can block the body’s response to substances which can damage the heart.

AICD’s and Pacemakers
• Some patients with heart failure can benefit from an automatic internal cardiac defibrillator (AICD) or biventricular (BiV) pacemaker. In order to qualify for an AICD the patient must:
- Have an EF or 30% or less, and - Have a history of CAD, although results of a recent clinical trial (SCD-HeFT) indicate that patients without CAD may also benefit

BiV Pacemakers
• In order to qualify for a BiV pacer, the patient must meet the qualifications for an AICD and:
- Have NYHA Class III or IV symptoms
- Have a QRS complex >120

Can a Person Live with Heart Failure?
YES!!!• Patients need regular follow-up
• Educating patients regarding signs and symptoms of heart failure is crucial

Discharge Teaching for Heart Failure Patients
• Take medications as prescribed. Don’t run out.
• Weigh daily. Weight gain of 3 pounds overnight, or 5 pounds in 5 days indicates fluid retention.
• Stop smoking.• Eat a low sodium diet.• Take blood pressure daily. Goal for most
patients is < 130/80.

Discharge Teaching for Heart Failure Patients
• Proceed with activity as you can tolerate it. If it makes you short of breath, slow down or stop. If you have chest pain, slow down or stop and if unrelieved by nitroglycerin, call your doctor or 911.
• Any questions, call your provider.
