Question

Which statement is accurate regarding the physiological changes associated with heart failure?

1. Blood backs up into the lungs due to right ventricular hypertrophy.
2. The walls of the heart shrink, leading to lower cardiac output.
3. Cardiac remodeling occurs after prolonged ventricular hypertrophy.
4. Blood pressure increases, resulting in lowered afterload.

Answer 1

Cardiac remodeling occurs after prolonged ventricular hypertrophy in heart failure.

Step-by-step explanation:

The accurate statement regarding the physiological changes associated with heart failure is that cardiac remodeling occurs after prolonged ventricular hypertrophy.

In heart failure, the heart undergoes a process called remodeling, where the structure and function of the heart adapt to the changes caused by prolonged ventricular hypertrophy (enlargement). This remodeling is characterized by changes in the size, shape, and composition of the heart muscle.

This remodeling can further impair the heart's ability to pump blood effectively and contribute to the progression of heart failure.
