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.

But there lay Captain Carpenter on his back
His weapons were the old heart in his bust
And a blade shook between rotten teeth alack.”
—John Crowe Ransom (1888–1974)
“With all their faults, trade-unions have done more for humanity than any other organization of men that ever existed. They have done more for decency, for honesty, for education, for the betterment of the race, for the developing of character in man, than any other association of men.”
—Clarence Darrow (1857–1938)
“Indigenous to Minnesota, and almost completely ignored by its people, are the stark, unornamented, functional clusters of concrete—Minnesota’s grain elevators. These may be said to express unconsciously all the principles of modernism, being built for use only, with little regard for the tenets of esthetic design.”
—Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)
