Any man who would leave his family in hock to their eyeballs just to gain such a small modicum of personal comfort for a very short time on his death bed doesn't deserve to live another minute. If it were me I'd put a gun to my head and be done with it.
With ordinarily good care, the heart increases its workload as the lungs become less effective. Quality of life and family interactions remain pretty decent. Eventually, either the heart enlarges so much that it competes for chest volume with the lungs, or the left ventriclar wall becomes so thick that it can no longer contract into the right shape to pump effectively. Then stuff goes bad.
