What is the result of hypertrophy and remodeling in the context of heart failure

A. Hypertrophy increases oxygen demand but does not improve cardiac function; it typically worsens ejection fraction. B. Hypertrophy and remodeling initially help compensate but over time lead to inefficient heart muscle with poor contractility and increased oxygen demand, contributing to worsening heart failure. C. Hypertrophy and remodeling increase, not reduce, workload, and do not resolve heart failure. D. Contractility often declines and oxygen demand increases, contrary to this statement.
