Hi,
Welcome to the ehealthforum and I am glad to help you out. Considering the clinical history and the complications which your boyfriend has gone through, the overall prognosis doesnât appear very bright. The risk of thrombosis (clotting) or bleeding (haemorrhage) is always there in such a scenario. Hence, maintenance of the PT/INR is very important. Itâs very difficult to predict the life expectancy. However, I am afraid to say but the overall prognosis doesnât appear good.
I sincerely hope that helps. Take care.
