ABSTRACT
Objective To investigate the effects of miRNA and hypersensitive C?reactive protein ( hs?CRP ) on non?targeted vessels in patients with acute coronary syndromes ( ACS ) after percutaneous coronary intervention( PCI) procedure. Methods The serum samples were collected from 217 cases ACS patients to detect the level of miRNA?14?5P and hs?CRP during admission and follow?up periods.All patients underwentPCI with stent implantation and coronary angiography,and CAG was performed at the time of 12?month follow?up.According to CAG results,the patients were divided into non target lesion progression group(progressiongroup) with 76 cases and non target lesion no progression group(no progression group) with 141 cases.Results The expression level of hs?CRP was significantly higher in progression group than the no progression group((1.65±0.18) mg/L vs.(1.52±0.37) mg/L,t = 3.478,P<0.001).The expression level of miRNA?142?5Pwas higher in progression group than the no progression group(27.12±2.11 vs.34.73±2.67,t = 23.035,P<0.001).Multi?factor regression analysis indicated that high expression levels of hs?CR and miRNA?142?5Pduring admission were the predictors of advance of non?targeted vessels patients(OR = 3.496,95%CI 2.046-5.981,P =0.001;OR =1.208,95%CI 1.073-1.361,P =0.002).Conclusion The serum level of hs?CRP andmiRNA?142?5P can predict non?targeted vessels in patients with ACS after PCI.
