Final answer:
Digoxin has no mortality benefit in congestive heart failure.
Step-by-step explanation:
In the treatment of congestive heart failure (CHF), there are several drugs used to improve symptoms and reduce mortality. However, one drug that has no mortality benefit in CHF is **digoxin**.
Digoxin is a medication used to control heart rate and improve symptoms of heart failure, such as shortness of breath and fatigue. While it is effective in reducing symptoms, it does not decrease mortality rates in patients with CHF.
This was demonstrated in a landmark study called the Digitalis Investigation Group (DIG) trial, which showed that digoxin did not reduce mortality in CHF patients compared to placebo or other medications.
