I am close to 70, and have lived with Heart Failure/Enlarged Heart for over 23 years. It has not been easy for me because I also have Valve Disease, Persistent Atrial Fibrillation, Asthma, Insulin Resistance, Chronically High Blood Pressure, and an over-active, over-reactive Immune System.
That said...... over the past six years, I have been getting progressively better, despite getting up there in age. In fact, at present I am awaiting the results of my annual Echocardiogram, which, I hope will show improvements in my Enlarged Heart, while not showing other problems, such as advancing valve disease.
I posted a thread here, under Heart Disorders, detailing exactly what I've done to improve my Heart Failure/Enlarged Heart and other health problems. The thread's title is: What I have done to survive Heart Failure & AFib with a high quality of life.

I started documenting my journey back to better health back in 2005, in a thread here titled: Does an "Insulin Resistance" diet improve blood pressure?

At that time, I did not realize the amazing, curative effect of a good diet on ALL of my health problems, including my Failed, enlarged heart.
I wish you and your mother the best of health, and I hope that her heart condition will improve!
