NYHA (New York Heart Association) functional classification of Heart Failure

In this article, we will discuss the NYHA (New York Heart Association) functional classification of Heart Failure. So, let’s get started.

Classification

Class I (Asymptomatic): No limitation on physical activity. Ordinary physical activity does not cause symptoms of Heart Failure (Patient with cardiac disease but no symptoms).

Class II (Symptomatic with moderate activity): Patients with cardiac disease are comfortable at rest and after mild activity, but moderate activity results in dyspnea, palpitation, and fatigue.

Class III (Symptomatic with mild activity): Patients with cardiac disease have marked limitation of physical activity. Comfortable at rest, but less than normal activity results in fatigue, dyspnea, and palpitation.

Class IV (Symptomatic at rest): Patients have symptoms of cardiac insufficiency at rest, and any physical activity further increases the discomfort. They are unable to carry out any physical activity without discomfort.
