In NYHA functional classification, which statement describes Class III?

• A. No physical limitation
• B. Noticeable limitations with physical activity
• C. Slight physical activity limitation
• D. Severe limitation of physical activity

Answer: (B)

The key idea is how NYHA classifies how heart failure affects daily activity. Class III means a marked limitation of physical activity: the person is comfortable at rest, but even but not excessive activity causes symptoms like fatigue or shortness of breath. The statement that describes noticeable limitations with physical activity fits this level best, because it conveys a substantial but not absolute restriction—more than a slight limitation but not a complete inability to be active. For context, no limitation is Class I, slight limitation is Class II, and Class III represents the point where activity is noticeably limited due to symptoms.
