You first must understand why the heart is failing, this is a long deep subject that is better asked about after you have read the web site, if you read that you should have most of the info needed to have an idea.
For now, eat fresh pineapple, remove all dental, stop all drugs/vitamins and other metals and remove all metal from the teethe. Make your own distilled water and drink no toxic drinks.
