Heart failure prognosis?

My mom was diagnosed with CHF in 2011. She had slight swelling in her left ankle for years but the hip joint in her left leg needed replacement but it was deemed too dangerous by surgeons because of her overall condition. She developed dementia and entered an AL in November 2017.

After entering the AL facility she had her first episode of both ankles and legs swelling to the knees rather severely. I guess it was a result of her being more active and walking a lot more (with a Rollator) at the facility.
She was seen by her doctor who adjusted her medication (diuretic).

So the doctor told you the truth. I’ve known of elders who had CHF for 10-15 years. So watch for the symptoms and keep in touch with the doctor.

I think it all depends on taking care of yourself. Keep your weight down. Eat well. Do what dr says. Light exercise. Watch salt intake. No drinking or smoking.

DeeAnna, excellent and knowledgable advice, as always.

Heart Failure depends on so many different variables that it acts differently in each person who has HF. There are different types of HF: Left-Sided HF, Right-sided HF, HF related to Pulmonary Hypertension, HF related to ????. So the doctor is correct when he said "everybody is different."

Doctors classify patients' heart failure according to the severity of their symptoms. The most commonly used classification system, the New York Heart Association (NYHA) Functional Classification1, places patients in one of four categories based on how much they are limited during physical activity.

My Dad had heart failure related to Pulmonary Hypertension and he lived 3 years after he started using oxygen. I think that you will find some good information on the American Heart Association website: www.heart.org/HEARTORG/Conditions/HeartFailure/

Your Mother could easily live until she is 95 years old if her heart failure does not progress very fast or your Mother might need to go into a nursing home within the next 2 years. It all depends...

The main thing is that you take care of yourself and your husband along with your Mother and know that whatever time you have left with your Mother will be "Very Good Years". Make some wonderful memories with your Mother!

Happy 63rd Birthday to You! {{{Hugs}}} & ^^^Prayers^^^
