The New York Heart Association (NYHA) Functional Classification provides a simple way of classifying the extent of heart failure. It places patients in one of four categories based on how much they are limited during physical activity; the limitations/symptoms are in regards to normal breathing and varying degrees in shortness of breath and or angina pain:
| NYHA Class | Symptoms |
|---|---|
| I | Cardiac disease, but no symptoms and no limitation in ordinary physical activity, e.g. shortness of breath when walking, climbing stairs etc. |
| II | Mild symptoms (mild shortness of breath and/or angina) and slight limitation during ordinary activity. |
| III | Marked limitation in activity due to symptoms, even during less-than-ordinary activity, e.g. walking short distances (20–100 m). Comfortable only at rest. |
| IV | Severe limitations. Experiences symptoms even while at rest. Mostly bedbound patients. |
Another frequently used functional classification of cardiovascular disease is the Canadian Cardiovascular Society grading scale of angina pectoris.
