What it is for
New York Heart Association (NYHA) functional classification of heart failure: it grades how much symptoms (breathlessness, fatigue, palpitations) limit physical activity; it is assigned by the clinician and can change with treatment. Classes in order:
Classification
| Category | Description |
|---|---|
| Class I | no limitation of physical activity; ordinary physical activity does not cause undue breathlessness, fatigue or palpitations. |
| Class II | slight limitation of physical activity; comfortable at rest, but ordinary physical activity causes breathlessness, fatigue or palpitations. |
| Class III | marked limitation of physical activity; comfortable at rest, but less than ordinary activity causes symptoms. |
| Class IV | unable to carry on any physical activity without discomfort; symptoms are present even at rest, and any activity increases the discomfort. |
