Study Notes
Functional Classification of Heart Failure
-
Functional Class 1: No limitations on physical activity; ordinary activities do not lead to symptoms such as fatigue, palpitation, dyspnea, or angina.
-
Functional Class 2: Slight limitations on physical activity; symptoms are absent at rest but manifest during ordinary activities, causing fatigue, palpitation, dyspnea, or angina.
-
Functional Class 3: Marked limitations in physical activity; individuals are usually comfortable at rest, but ordinary activities result in symptoms like fatigue, palpitation, or dyspnea.
-
Functional Class 4: Severe limitations; individuals are unable to perform physical activities without discomfort, experience heart failure symptoms at rest, and have increased discomfort during any activity.
AHA Stages of Heart Failure
-
AHA Stage A: Presence of risk factors for heart failure without any structural heart disease or noticeable heart failure symptoms.
-
AHA Stage B: Indicators of structural heart disease exist, yet patients do not exhibit any symptoms of heart failure.
-
AHA Stage C: Structural heart disease is present along with previous or current heart failure symptoms; symptoms are managed through medical treatment.
-
AHA Stage D: End-stage heart disease characterized by persistent heart failure symptoms at rest, despite comprehensive medical therapy efforts.
