Hi Wojtek,
I am happy you are here with us to tell your story. Hopefully you are feeling a little better as each day goes by.
Yes, there are studies showing a state of hypercoagulation in diving;
however, most of the papers out there are focused on symptomatic decompression illness. There are also a handful which have been done on saturation diving.
Of the papers I have seen on coagulation in diving, the most applicable (measuring changes in coagulation markers and platelet count in asymptomic dives) to your situation/question would be:
Hematologic changes after daily asymptomatic dives

The Baj group is working out of Poland with the Military Medical Academy, btw.
Best wishes and take care,
