Overview

There are several classification schemes used to characterize the pathophysiology of heart failure as either systolic vs diastolic; left vs right; or low output vs high output.

Classification

There are several classification schemes used to characterize heart failure which include:

Systolic versus Diastolic Heart Failure

Patients may be broadly classified as having heart failure with depressed contractility or depressed relaxation.

Systolic Dysfunction

The left ventricular ejection fraction is reduced in systolic dysfunction and there is depressed contractility of the heart.

Disastolic Dysfunciton

The left ventricular ejection fraction is preserved in diastolic dysfunction and there is an abnormality in myocardial relaxation or excessive myocardial stiffness. Systolic and diastolic dysfunction commonly occur in conjunction with each other.

Left, Right and Biventricular Failure

Another common method of classifying heart failure is based upon the ventricle involved (left sided versus right sided).

Left Heart Failure

  • There is impaired left ventricular function with reduced flow into the aorta.

Right Heart Failure

  • There is impaired right ventricular function with reduced flow into the pulmonary artery and lungs.

Biventricular Failure

  • The most common cause of right heart failure is left heart failure, and mixed presentations are common, especially when the cardiac septum is involved.

High Output Versus Low Output Failure

Low Output Failure

High Output Failure

Chronicity of Heart Failure

Acute or Decompensated

Acute or decompensated heart failure is a term used to describe exacerbated or decompensated heart failure, and refers to an episode in which a patient sustains a change in heart failure signs and symptoms that necessitates urgent therapy or hospitalization.[2]

Chronic

There is stable symptomatology in chronic heart failure.

Assessing the Severity of Heart Failure: The New York Heart Association Criteria (NYHA)

  • NYHA I: No symptoms with ordinary activity.
  • NYHA IV: Unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency present at rest.

ACC/AHA Classification of Chronic Heart Failure Based on the Structural and Symptomatic Stages of the Syndrome

The ACC/AHA classification system was introduced to emphasize the natural history of the heart failure syndrome and to identify opportunities to intervene earlier and prevent disease progression.

Stage A

Patients “at Risk”

Stage B

Patients with structural heart disease, but no history of signs or symptoms of heart failure.

Stage C

Underlying structural heart disease and symptoms of heart failure.

  • Dyspnea or fatigue due to left ventricular systolic dysfunction.
  • Asymptomatic patients receiving treatment for prior symptoms of heart failure.

Stage D

Despite of maximal medical therapy, symptoms of heart failure at rest and advanced structural heart disease.

  • Being considered for advance options including LVAD and heart transplantation.
  • Requiring continuous inotropic or mechanical support.
  • Receiving or being considered for palliative care/end of life care.

Classification of heart failure Based on the Ejection Fraction (EF)

  • The 2013 ACC/AHA guidelines indicated that the EF is the most accurate way to classify heart failure rather than systolic vs diastolic. That is due to the variation in the definition of systolic dysfunction with some defines it as an EF < 35%, < 40% and <= 40%.
  • For 2013 guideline, HFrEF is defined as the clinical diagnosis of heart failure, with an EF less than or equal to 40%.
