It was fairly well known when all the articles were geared toward men and heart disease that they could have depression after heart surgery even up to 6 mo. out. So I would guess the same was true for women, but I can't say for sure. I agree with all the others who have said to report this to here pcp (primary care physician) and get his advice. I haven't had heart surgery but have had several major surgeries and have always had some depression afterwards. It was always difficult but eventually faded (the one time forgetting was welcome)! Good luck.
