Stage B HF is defined as ...

• A. Structural heart disease with HF symptoms
• B. End-stage HF with frequent hospitalizations
• C. Structural disease without EF changes
• D. No symptoms but decreased EF and showing signs of structural disease

Answer: (D)

Stage B HF means there is structural heart disease but no signs or symptoms of heart failure. The correct statement fits that idea by saying there is no HF symptoms, yet there is clear structural heart disease evidenced by a reduced ejection fraction and other signs of structural changes. This captures the scenario of having an abnormal heart structure or function without yet having HF symptoms.

If HF symptoms were present, that would align with a later stage where symptoms are part of the picture. End-stage HF with repeated hospitalizations would be a more advanced stage, and a description of structural disease without any EF changes could still be structural disease, but the inclusion of decreased EF in the chosen option helps clearly illustrate the presence of structural disease with the absence of symptoms, which is the essence of Stage B.
