New York Heart Association Functional Classification

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:

I No symptoms and no limitation in ordinary physical activity.
II Mild symptoms and slight limitation during ordinary activity.
Comfortable at rest.
III Marked limitation in activity due to symptoms, even during less-than-ordinary activity.
Comfortable only at rest.
IV Severe limitations. Experiences symptoms even while at rest.
