In the treatment of chronic heart failure, what role do diuretics primarily serve?

• A. Lowering blood pressure
• B. Eliminating excess fluid
• C. Increasing heart rate
• D. Improving circulation

Answer: (B)

In the treatment of chronic heart failure, diuretics primarily serve the role of eliminating excess fluid. Heart failure often leads to fluid retention due to the heart's reduced ability to pump blood effectively, causing congestion in the lungs and other tissues. Diuretics help to increase the excretion of sodium and water through the kidneys, which reduces the volume of fluid in the body. This alleviates symptoms such as edema (swelling) and pulmonary congestion, thereby improving the patient's quality of life. While some diuretics may indirectly influence blood pressure, their main purpose is not hypertension management but fluid balance. Diuretics do not increase heart rate or directly improve circulation; instead, by reducing fluid overload, they can help relieve some symptoms of heart failure and allow the heart to function more effectively. Thus, option B accurately captures the primary purpose of diuretics in managing chronic heart failure.
