In the functional classification of heart failure, which class is described as having no cardiac symptoms with ordinary activity?

• A. Class II
• B. Class I
• C. Class III
• D. Class IV

Answer: (B)

The key idea is the New York Heart Association functional classification, which groups heart failure by how much symptoms limit daily activity. The description of having no cardiac symptoms with ordinary activity fits the highest level of function: there is no limitation in physical activity, and ordinary activities do not provoke heart failure symptoms. Patients can perform normal tasks without breathlessness, fatigue, or chest discomfort. If someone encounters broader categories: a slight limitation means comfortable at rest but symptoms appear with ordinary activity; a marked limitation means symptoms with less-than-ordinary activity; and symptoms present even at rest define the most severe class. This framework helps clinicians assess severity and tailor treatment.
