The following is a classification for
heart failure devised by the New York Heart
Association (NYHA). It is important to be familiar with this classification,
because it may be referred to during the course of your care.
Classification of heart failure symptoms | Class I |

physical activity does not cause undue fatigue, heart palpitations, trouble
breathing, or chest pain. |

People who have some limitation on physical activity. They are
comfortable at rest, but ordinary physical activity causes fatigue, heart
palpitations, trouble breathing, or chest pain. |
|---|
| Class III |
People who have a marked limitation on physical activity. They
are comfortable at rest, but less-than-ordinary physical activity causes
fatigue, heart palpitations, trouble breathing, or chest pain. |

People who are unable to carry on any physical activity without
discomfort. Symptoms may be present even at rest. If any physical activity is
