Hi, and thank you for coming to JustAnswer.com with your question.
It certainly sounds like your husband is setting himself up to be a very sick man.
As far as his heart goes, it is important that his high blood pressure be controlled (ie he should be taking medication that brings it down to within the normal range). He also needs to be treated for him high cholesterol with medications (as you said he is on statins) and blood work has to be done regularly to ensure that his cholesterol levels are under control.
All the wine he is drinking can have a negative effect on his liver. The fact that you think he sometimes looks a bit yellow (in medical terminology that is called jaundice) it seems like most likely he is starting to have some effects on his liver. This is also something that has to be checked with a blood test.
It is important for him to also know that many medications do not interact well with alcohol.
His coughing all the time could be secondary to his COPD - chronic bronchitis would cause this, but as he's been exposed to many gasses he should certainly be monitored to ensure he is not experiencing decline in lung function as well as that he is not developing any masses in his lungs.
You did not mention if he smokes, but that would make the monitoring of his lungs, with chest x-rays as appropriate extremely important.
I see that you are offline so I will change this to a question/answer type exchange.
Please let me know what more you would like to know, if there are any specifics you are trying to find out about that I haven't touched upon.
Wow, I've seen how hard that can be.There really is no way to give a true estimation of how long he will live while doing these things. From what you are describing I would expect that whatever does eventually get him, it will not be imediate and painless. From what you are describing of him:Heart disease can take many years to kill. Usually people start developing heart failure which gets worse over time. During this period of declining heart health and declining ejection fraction (this is what we use to determine how well his heart is working) people become progressively more short of breath - starting with the shortness of breath (if you ever see SOB on his chart don't be offended - it stands for shortness of breath) with exertion (which you say is where he is at now), then continues until the SOB is even without exertion. Also the lungs may fill with water as the heart is not pumping efficiently.I don't have to tell you what can happen as far as if it is his COPD that gets him.Liver disease also can be a prolonged and painful process.Here is a link to an article that discusses the fact that many patients with congestive heart failure think they have a longer life expectancy than they actually have in reality.http://www.webmd.com/heart-disease/heart-failure/news/20080603/heart-failure-patients-too-optimisticI'm going to look through some of my sources and see what other information might be helpful for you.Something important to remember is that The Doctor is not G-d. One of the worst things you can do to yourself is try to get firm numbers (as tempting as it is). In a personal case, my father was told that his mother's life expectancy at a certain point was 2 year. She lived for 7, but during those last 5 years (after the expectancy of 2) my father was always anxious that the next call he got from home would be to tell him this the end had come.
Thank you for your kind offer but I don't think it would make any difference. Our GP is lovely but very gentle in his manor he is unlikely to be hard and brutal enough to get Gavin to listen
I really don't think it looks very good
Thank you for your help it is much appreciated and at least now I don't think I am over reacting.
All the best
