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