Alcohol related heat failure occurs in people who are heavy drinkers, say 12 beers a day or heavy use of hard liquor. There is some recent data out that 1 to 2 drinks of red wine per day may actually prevent heart attacks, and I think that is what you are mentioning in you comments. There is no clear-cut number of drinks associated with heart failure. The alcohol heart failure is usually in alcoholics, and the condition is called alcoholic cardiomyopathy. Somehow, in those patients, the alcohol damages the heart muscle.
Heart transplant is one of the last resorts for treating severe heart failure.
We reserve heart transplants for the sickest patient who would not live long without a new heart. Heart transplant is a big deal and requires intensive medical management before and after the heart transplant. The heart pumps are currently being studied to see if they are an alternative to heart transplants. Basically, the heart pumps were used to keep people alive until their heart became available for transplant. We have to decide if their heart is sick enough to need a transplant, and we have to see if they are good candidates for transplant.
