Abstract:
Objective To investigate the relationship of the serum levels of high sensitivity C-reactive protein(hs-CRP) and homocysteine with middle cerebral artery(MCA) intraplaque hemorrhage.Methods A total of 63 patients who met the inclusion criteria showed high-grade(≥ 70％)MCA stenosis.The levels of serum hs-CRP and Hcy were detected.All patients were divided into symptomatic group and asymptomatic group,intraplaque hemorrhage group and non-intraplaque hemorrhage group.All patients performed conventional MRI and high-resolution MRI(HR-MRI).The correlation of the serum levels of hs-CRP and homocysteine with middle cerebral artery intraplaque hemorrhage was analyzed.Results Totally 37 symptomatic and 26 asymptomatic MCA stenoses were analyzed.The occurrence rate of intraplaque hemorrhage was significantly higher in symptomatic MCA stenosis group than in asymptomatic MCA stenosis group (40.5 ％ vs.11.5 ％,x2 =6.29,P＜ 0.05).Symptomatic group displayed a higher hs-CRP and Hey levels (8.97 ± 3.36 mg/L and 20.00 ± 3.16 μmol/L,respectively) than did asymptomatic group [(5.26 ± 3.12) mg/L and (12.22 ± 1.88) μmol/L,t =4.43 and 11.23,respectively,each P ＜ 0.001].The hs-CRP and Hcy levels were higher in intraplaque hemorrhage group [(10.53 ± 3.59) mg/L and (21.70 ± 2.40) μmol/L,respectively] than in non-intraplaque hemorrhage group[(6.20 ± 3.02) mg/L and(11.77±1.69) μmol/L,t=4.87 and 18.58,respectively,each P＜0.001].The hs-CRP and Hcy levels were positively correlated with the risk for middle cerebral artery intraplaque hemorrhage(r=0.461 and 0.519,each P＜0.001).Conclusions The serum levels of hs-CRP and Hcy are closely associated with middle cerebral artery intraplaque hemorrhage,which can be used to evaluate the stability of plaque.The MCA intraplaque hemorrhage is associated with ipsilateral stroke.
