Abstract: ObjectiveTo study the effect of platelet aggregation rate (PAR) level on the prognosis of percutaneous transluminal coronary angioplasty (PCI).MethodsFour hundred and one patients who performed PCI were divided into 4 groups:group 1 (PAR≤30％,103 cases),group 2 (PAR 31％ - 40％,102 cases),group 3 (PAR 41％ - 49％,103 cases ) and group 4 (PAR ＞ 49％,93 cases ).All the patients were followed up.The survival analysis was performed in 4 groups.ResultsThe data of survival table were tested by 3 methods among 4 groups:statistic was 0.612,degree of freedom was 3,P =0.894 in Log-rank (Mantel-Cox) test,statistic was 0.567,degree 9f freedom was 3,P =0.904 in Wilcoxon test and statistic was 0.586,P =0.900 in Tarone-Ware test.There was no significant difference among them.The mean follow-up duration was 2.2 years,and there was no significant difference in survival function among 4 groups (P ＞0.05).ConclusionPreoperative and postoperative measurement of PAR levels may not improve the prognosis.
