Dear Marcy, thank you for your question. Depression is frequently seen after an illness like a heart attack and since your friend is prone to alcohol dependency, he is at higher risk of developing depression. I can't say whether his alcoholism or his response to his heart attack is the cause of his depression, but he needs professional help for both problems. Additionally, dementia may be playing a role as well. Thus, I strongly advise you to bring your friend to his physician's office and to demand treatment for the depression and alcoholism.
