The NYHA: is used to classify heart failure patients into one of 4 categories across patient symptoms and objective assessment via a questionnaire format related to their limitations, if any, during physical activity. Classes of patient symptoms are: Class I: No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, dyspnea (shortness of breath). Class II: Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea (shortness of breath). Class III: Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, or dyspnea Class IV: Unable to carry on any physical activity without discomfort. Symptoms of heart failure at rest. If any physical activity is undertaken, discomfort increases. Classes of Objective Assessment are: Class A: No objective evidence of cardiovascular disease. No symptoms and no limitation in ordinary physical activity. Class B: Objective evidence of minimal cardiovascular disease. Mild symptoms and slight limitation during ordinary activity. Comfortable at rest. Class C: Objective evidence of moderately severe cardiovascular disease. Marked limitation in activity due to symptoms, even during less-than-ordinary activity. Comfortable only at rest. Class D: Objective evidence of severe cardiovascular disease. Severe limitations. Experiences symptoms even while at rest.
Should not be used alone as an indication of CHF severity as the classification is an approximation.
