cyanotic nose 9 mos after coronary bypass

Hi, my husband had a coronary bypass surgery in March 2012, and I notice that his mind hasnt improved. He is as demented as he was before the surgery, if not more. I also noticed the last month or so that his nose is getting cyanotic again. Is that a bad news sign ?

Hi,
How is your husband? After coronary by pass, problems involving cardiac problems,complications of surgery, gastrointestinal difficulties and a wide variety of problems in other organ systems are often observed. Studies have shown also that a significant proportion of CABG patients experience psychological difficulties post surgery and there is increasing recognition that the procedure may be a risk factor for subtle cognitive decline or psychological abnormalities. Cognitive decline may present as short-term memory loss, psychomotor slowing, or executive dysfunction. (ref: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1994021/)
It is best that you have him see his attending physician for proper evaluation. Additional diagnostic tests may need to be done also to evaluate the cyanosis present. Take care and do keep us posted.
