The Relationship Between Platelet Count And Coronary In-stent Restenosis

Objective:To investigate the possible association between platelet count and coronary in-stent restenosis (ISR) after drug-eluting stent implantation.Methods:The study enrolled240patients who underwent stent implantation and accepted coronary angiography in1year. A≥50%-diameter stenosis was used as a definition of ISR. Multiple clinical data and risk factors of coronary heart disease were collected, and the platelet count was detected, the correlation between platelet count and ISR was analyzed.Results:Among the240patients, restenosis occurred in80patients, compared to non-stenosis group, platelet count were higher in restenosis group, which reached significant statistic difference (185.25±284.75vs155.66±144.34, P<0.05).Conclusions:platelet count is significantly correlated with in-stent restenosis after drug-eluting stent implantation in coronary artery.
