Which NYHA class describes mild symptoms with ordinary activity?

• A. Class I: No limitation of physical activity
• B. Class III: Marked limitation with minimal activity
• C. Class II: Mild symptoms with ordinary activity
• D. Class IV: Unable to carry out any physical activity without discomfort

Answer: (C)

The NYHA functional classification describes how heart failure limits daily activities, with increasing symptoms as activity becomes more demanding. Mild symptoms that appear with ordinary activity indicate a slight limitation in activity, which is Class II. In this class, patients are comfortable at rest, but ordinary activities may bring mild symptoms such as fatigue or shortness of breath. In contrast, Class I has no limitation, Class III has marked limitation with less-than-ordinary activity, and Class IV has symptoms even at rest. So the description aligns with Class II.
