I didn't really know what congestive heart failure was before doing some reading just now. It sounds like a quite serious disease. In some of the literature I read, it said that if the cause is treatable, heart failure can go away. Other literature said there are treatments available that can help manage the symptoms and improve the quality of life. But in other literature it said it's not treatable. I guess it comes down to each individual's circumstance. I also read that "Since you can’t move backward through the heart failure stages, the goal of treatment is to keep you from moving forward through the stages or to slow down the progression of your heart failure."

What has your cardiologist been doing the last 4 years to help slow down progression? What do they think the underlying cause is? Is it genetic?

The following URL has a table showing the most common treatments for each stage of heart failure. On this page, it also says "The heart failure program at Penn Medicine is the largest on the East Coast with specialized cardiologists that are solely dedicated to treating you, or your loved ones living with heart failure, or its affects."

The following URL also lists treatments by stage, but seems to recommend additional treatments at stage 3 (what they call stage C):

You might also send your cardiologist the link below related to current or upcoming clinical trials of CFH and see if he/she thinks any of these could be beneficial to you:

You might also do some reasch at the following reputable medical websites:

I hope this helps and I hope for the best possible outcome for you.
