RESUMO
Objective :To explore influence of nicorandil on plasma levels of high sensitive C reactive protein (hsCRP) and soluble T cell CD40 ligand (sCD40L) and therapeutic effect of nicorandil in patients with microvascular angina pectoris .Methods :A total of 102 patients with microvascular angina pectoris were enrolled ,randomly and equally divided into routine treatment group (received routine comprehensive treatment ) and nicorandil group (received nic-orandil based on routine comprehensive treatment ,5mg ,3 times/d) ,both groups were treated for eight weeks . Plasma levels of hsCRP and sCD40L were measured and compared between two groups before and eight weeks after treatment ,and therapeutic effect was compared between two groups .Results : Compared with before treatment there were significant reductions in plasma levels of hsCRP and sCD 40L in both groups after eight weeks ;compared with routine treatment group after treatment ,there were significant reductions in plasma levels of hsCRP [ (2.63 ± 0.25) mg/L vs.(1.80 ± 0.28) mg/L] and sCD40L [ (71.88 ± 3.71) pg/ml vs .(55.25 ± 2.47) pg/ml] in nicorandil group , P＝0. 001 all.Total effective rate of nicorandil group was significantly higher than that of routine treatment group (78.43% vs.56.86%,P＝0.02).Conclusion :Nicorandil can significantly rise clinical effect ,reduce plasma levels of hsCRP and sCD40L in patients with microvascular angina pectoris .
