What is the prognosis for someone with a left ventrical ejection fraction of 20-25% and cardiomyopathy?

That is difficult to answer without more information on your history.
Cardiomyopathy with a low ejection fraction puts you at higher risk for dangerous arrythmias.
You may be a candidate for a Biventricular ICD (an implanted pacemaker/defibrillator). This is a device which can pace both ventricles simultaneously to mimic a more natural heart contraction, thus boosting your cardiac output. Regular pacemakers only pace one ventricle .It can also detect and terminate any dangerous heart rhythms.
Your cardiologist could refer you to an Electrophysiologist (a specialist in heart rhythms) for evaluation.
Many people feel noticeably better after having one implanted.
You might find more information on the Heart Rhythm Society webpage.
Good Luck :o)

Sounds like a case for cardiac transplant.

Ask the doctor, moron!

You need to ask your doctor this. Your doctor knows you better than any of us Answers people ever could.

The prognosis -bad. But! My diagnosis was dilated cardiomyopathy, pneumosclerosis.Go on a site of "Health and Life" foundation - www.fhal.ru read section "My treatment". In my struggle, I use a breathing device simulator TFI as well as energy 鈥渁bsent鈥?and 鈥減resent鈥?Doctor S.S.Konovalov鈥檚 treatment.The results - very good.Ejection fraction increased from 19 % to 43 %. Best wishes to you and your family.

my husband had ejection fraction rate of 22% before he was referred on to a transplant center. A year later at the last check it had dropped to 17% before he had his well needed heart transplant. He too suffered from Cardiomyopathy which i believe is Heart faliure and thats why the ejection fraction rate is low. Transplant is only considered as a last option as it's such a massive thing to go through.
Good Luck and i wish you well. I hope this helps.
