The purpose of this study was to measure the changes in haemostasis an
d fibrinolytic parameters in the course of PTCA in patients receiving
either standard medication (n = 15) (10 000 units of heparin and 250 m
g of ASA) or additional therapy (n = 16) contained agent causing incre
ase in fibrinolytic activity (200 mg of SP-54((R))). We found in both
groups increased values of TAT, F 1+2, PAP, D-dimer, PAI-1 and t-PA. T
here were no significant differences in any of the variables measured,
except t-PA values obtained after vs before PTCA were significantly e
levated in patients receiving SP-54((R)) (p < 0.02). Between the two g
roups there were also differences in t-PA activity obtained after PTCA
(p < 0.05). The additional therapy caused neither major bleeding comp
lication nor ''paradoxic thrombotic incident'' as was observed in thro
mbolytic therapy. To define the real impact of SP-54((R)) on haemostas
is during PTCA, a randomised trial in a larger population is warranted
.
