My dad has CHF, past open heart surgery, black lung disease...Cleveland CLinic would not give him an lvad because of his lung condition.  His bnp is 6795 and he is now starting to sleep a lot...he slept for 17 hours.  Do you think the end is near for him.
Thanks for your question on Chat Doctor. I can understand your concern. Yes, his end is near. Black lung disease can cause respiratory failure in terminal stages. This respiratory failure causes carbon dioxide retention (CO2 retention) in the body. This will cause excessive sleepiness. All these will be more pronounced if patient is having heart failure simultaneously. So your father is sleeping for 17 hours is because of heart and respiratory failure. And this is not good sign for prognosis. Gradually, his condition will worsen, and ultimately he will go in deep coma and death. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
