Which statement correctly describes NYHA Class I?

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

Answer: (D)

The key idea is how the NYHA functional classes describe heart failure symptoms with activity. For NYHA Class I there is no limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, or dyspnea. This sets Class I apart from the higher classes, where activity typically provokes symptoms. For context, Class II means a slight limitation with ordinary activity causing symptoms, Class III signifies a marked limitation with less than ordinary activity triggering symptoms, and Class IV describes symptoms at rest or inability to carry out any activity without discomfort. So the statement that best describes NYHA Class I is that there is no physical limitation.
