It Appears That My 82 Year Old Mother Had A

It appears that my 82 year old mother had a heart attack two weeks ago she went to the dr because of a serious cough, weakness and shortness of breath. The chest X-ray shows fluid in the right lounge which has caused the cough. The fluid will be drained tomorrow... Heart tests will be run also... Shout we expect her to need heart surgery or medication ? How much would this shorten her life? She also has a fatty liver
