How do ACE inhibitors help in treating heart failure?

  1. By increasing blood volume

  2. By causing diuresis

  3. By increasing afterload

  4. By increasing SVR

The correct answer is: By causing diuresis

ACE inhibitors help in treating heart failure by causing diuresis, or the increased production of urine, which helps to reduce fluid buildup in the body and decrease the workload on the heart. Option A, increasing blood volume, would have the opposite effect and worsen heart failure. Option C, increasing afterload, would also worsen the condition by increasing the pressure that the heart has to work against. Option D, increasing SVR (systemic vascular resistance), would lead to increased blood pressure which can further strain the heart. Therefore, option B is the most appropriate answer for how ACE inhibitors help in treating heart failure.
