Overview[edit | edit source]

LVEF has an important role in the classification of patients with HF because of differing prognosis and response to treatments. In the guideline of 2022 AHA, HFrEF is defined as LVEF ≤40% . HF with preserved EF (HFpEF) including approximately 50% of the population with HF with increased prevalence. HFpEF is defined as LVEF ≥50%. Heaet failure improved EF is considered when follow-up LVEF reaches more than 40%.

Classification[edit | edit source]

Several classification systems are used to characterize heart failure according to the: [1] [2]

  • The pathophysiology of heart failure:
    • Systolic vs diastolic heart failure
    • Left-sided, right-sided or biventricular heart failure
    • Low output vs high output heart failure
  • The underlying physiology based on left ventricular ejection fraction:
  • The chronicity of heart failure:
    • acute or chronic
  • The severity of symptoms of heart failure:
    • New York Heart Association Class (NYHA class)
    • Killip class (severity of the symptoms in the acute setting after myocardial infarction)
  • The stage (progression of the disease) of congestive heart failure:
    • The American College of Cardiology Foundation/American Heart Association (ACCF/AHA) classification: A, B, C, D.

1. Systolic versus Diastolic Heart Failure[edit | edit source]

2. Left-, Right- and Biventricular Failure[edit | edit source]

Another common method of classifying heart failure is based upon the ventricle involved.

  • Left-ventricular Heart Failure: There is impaired left ventricular function with the reduced flow into the aorta.
  • Right-ventricular Heart Failure: There is impaired right ventricular function with the 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.

3. High output versus Low output Heart Failure[edit | edit source]

4. Classification of Heart Failure Based on the Ejection Fraction (EF)[edit | edit source]

Abbreviations: HF: Heart failure; HFmrEF: Heart failure with mildly reduced ejection fraction; HFpEF: Heart failure with preserved ejection fraction ; HFrEF: Heart failure with reduced ejection fraction; LV: Left ventricle; LVEF: Left ventricular ejection fraction;

HFrEF HFmrEF HFpEF
Symptoms± Signs, LVEF ≤ 40% Symptoms± Signs, LVEF ≥ 41%-49% Symptoms± Signs, LVEF≥ 50%, cardiac structure and function abnormalities,

LV diastolic dysfunction, high LV filling pressures, high natriuretic peptides

The above table adopted from 2021 ESC Guideline

[4]


Classification of heart failure by LVEF
Type of heart failure according to LVEF Criteria
HFrEF (heart failure with reduced EF) LVEF ≤ 40%
HFimpEF ( heart failure with improved EF)

Previous LVEF ≤ 40% and a follow-up measurement of LVEF>40%

HFmrEF (heart failure with mildly reduced EF)
HFpEF (heart failure with preserved EF)
The above table adopted from 2022 AHA Guideline

[5]

5. Chronicity of Heart Failure[edit | edit source]

  • 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.[6]
  • Chronic: There is stable symptomatology in chronic heart failure.

6. The Severity of Heart Failure[edit | edit source]

The NYHA functional classification is used to describe the severity of symptoms and exercise intolerance in patients with congestive heart failure.

The New York Heart Association Criteria (NYHA)
NYHA Class Definition
NYHA I No symptoms with ordinary activity
NYHA II

Slight limitation of physical activity. Comfortable at rest, but ordinary physical activity results in fatigue, palpitation, dyspnea, or angina.

NYHA III

Marked limitation of physical activity. Comfortable at rest, but less than ordinary physical activity results in fatigue, palpitation, dyspnea, or anginal pain.

NYHA IV Unable to carry out any physical activity without discomfort. Symptoms are present at rest.

7. The Stages of heart failure[edit | edit source]

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.

2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines. Stages of Heart Failure
Stages Definition Example Corresponding NYHA class
A
  • Patients at high risk for developing HF but without structural heart disease or symptoms of heart failure or biomarkers within normal ranges.
None
B Patients without current or previous sings/ symptoms of HF but evidence of the following:
  • Structural heart diseases.
  • Increased filling pressures in the heart.
  • Increased levels of Natriuretic peptide.
  • Persistently elevated cardiac diagnosis with no diagnosis.
NYHA class I
C Patient with past or current symptoms/ signs of HF The trajectory of Stage C HF:
  • New onset/ De Novo HF
  • Resolution of symptoms
  • Persistent HF
  • Worsening HF
NYHA classes I, II, III, and IV
D Profound HF symptoms. Patients have symptoms that interfere with daily life activities. They may also have recurrent hospitalizations despite attempts to optimize guideline-directed medical therapy. NYHA class IV
