Table I

NYHA classification of cardiac functional capacity and objective assessment*.

Class I. Patients with cardiac disease but without resulting limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitations, dyspnoea, or anginal pain. There is no objective evidence of cardiovascular disease.
Class II. Patients with cardiac disease resulting in slight limitation of physical activity. They are comfortable at rest. Ordinary physical activity results in fatigue, palpitations, dyspnoea, or anginal pain. There is objective evidence of minimal cardiovascular disease.
Class III. Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary activity causes fatigue, palpitations, dyspnoea, or anginal pain. There is objective evidence of moderately severe cardiovascular disease.
Class IV. Patients with cardiac disease resulting in the inability to carry out any physical activity without discomfort. Symptoms of heart failure or the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort active increases. There is objective evidence of severe cardiovascular disease.
