What's the best treatment for heart failure? my father was getting treatment for kidney cancer and has developed heart failure alongside that and his ef is only 20%. what's the best treatment for his heart failure? his bp is also low (91/61?

That would be determined by the physician who knows all the features of the case including the other treatments/meds in use. There is no one best treatment for heart failure. There are treatments that must be refined to match the individual patient needs.

This cannot be treated on line and needs a thoro exam. There are treatments for it. Pl see a Cardiologist Hope your dad feels better
