Clinical dynamics of the coagulation system and the dose of warfarin. (a) PT-INR was the highest on day 8, but improved with vitamin K supplementation and reduction of warfarin. (b) PT and APTT. After day 8, APTT was prolonged over PT, suggesting APTT dominance.(c) D-dimer was the highest on day 8, but declined during the latter part of the clinical course. (d) Platelet count in the peripheral blood was the lowest on day 17, but readily recovered since then.
