Which medication is considered safe for a patient suffering from congestive heart failure?

Explanation

Among the listed drugs, acetaminophen (paracetamol) is the safest option for patients with congestive heart failure, as it does not adversely affect heart function. Nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin, diclofenac, and ibuprofen can worsen heart failure by causing fluid retention and increasing blood pressure.
