Abstract:
The aim was to verify the effectiveness of slide platelet aggregation test (SPAT) to monitor the inhibition effect of anti-platelet drugs. A group of eight healthy volunteers was examined for SPAT value and T(50) (time necessary for reaching 50% of total aggregation) induced by ADP, arachidonic acid (AA) and cationic propyl gallate (c-PG) respectively before and after administration of ASA in dose of 100 mg/day for 3 days. The group of 41 inpatients at the Department of Cardiovascular Disease treated with anti-platelet drugs and the group of 327 healthy blood donors were also examined for SPAT. The SPAT value of healthy volunteer samples stored at room temperature were measured hourly for four hours. The results showed that: (1) no significant difference was detected between the T(50) before and after ASA administration in health volunteer group when ADP was used as inducer, but a significant difference was detected in this group when AA or c-PG was used as inducer. There was significant linear correlation between SPAT value and T(50) induced by c-PG in health volunteer group before and after administration of ASA (r = 0.998, P = 0.000); (2) there was no significant difference between the SPAT value of health volunteer group before administration of ASA and the SPAT value of health blood donors group (P = 0.853), but there was a significant difference between the SPAT values before and after administration of ASA in health volunteer group (P = 0.000). There was significant difference when the SPAT value of the inpatients treated with anti-platelet drugs was compared with that of healthy blood donor group and with that of health volunteer group before and after administration of ASA (P = 0.000). The cut-off value of SPAT in health blood donor group was 44.6 +/- 11.7 seconds, reference value was from 21.1 seconds to 68.0 seconds; (3) there was no significant difference between SPAT values when platelets samples stored at room temperature for 1, 2, 3, 4 hours (P = 0.815). In conclusion, SPAT can rapidly monitor the inhibition effect of anti-platelet drugs and SPAT may have the similar clinic value with T(50) induced by c-PG.
