【目的】探讨非ST段抬高型急性冠脉综合征（NSTE‐ACS）患者高敏C反应蛋白（hs‐CRP）水平与冠状动脉狭窄程度、肌钙蛋白T（cTnT）的相关性。【方法】根据患者入院时的血清hs‐CRP水平将225例确诊为NSTE‐ACS的患者分为正常组（≤3mg／L，n＝105）和升高组（＞3mg／L，n＝120）。采用微粒子增强透射免疫分析法测定hs‐CRP、电化学发光法测定cTnT，同时作冠状动脉造影定量计算冠状动脉病变积分（CAS），评价冠状动脉狭窄程度。【结果】升高组与正常组CAS评分差异无统计学意义[（491．4±318．0）分vs（508．1±346．4）分，t＝04．39，P＞00．5）]；升高组血清cTnT显著高于正常组，差异具有统计学意义[（37．8±14．2）mmol／Lvs（18．9±15．9）mmol／L，t＝21．48，P＜00．5）]；hs‐CRP水平与cTnT水平呈显著正相关（r＝04．78，P＜00．5），与CAS水平呈负相关，但差异无统计学意义（r＝01．69，P＞00．5）。【结论】血清hs‐CRP水平对NSTE‐ACS的诊断具有重要的临床价值，但与冠状动脉狭窄病变程度无明显相关性。“,”[Objective]To study the relations among the high sensitive C‐reactive protein (hs‐CRP) ,the coronary ar‐tery stenosis ,and Troponin T (cTnT ) in patients with Non‐ST‐elevation acute coronary syndromes (NSTE‐ACS) .[Methods]According to hs‐CRP level ,225 patients diagnosed as NSTE‐ACS in our hospital were divided into two groups (Group A with normal level hs‐CRP≤3 mg/L ,n =105 and Group Bwith high level hs‐CRP >3 mg/L ,n =120) .Data of coronary stenosis score (CAS) and quantity of Troponin T (cTnT ) in both groups were compared and analyzed .[Re‐sults]There was no difference in coronary stenosis score between the two groups [(49 1.4 ± 31 8.0) vs (50 8.1 ± 34 6.4) ,t=0 4.39 ,P >0 0.5] .However ,the quantity of Troponin T in Group B was higher than that of in Group A[ (3 7.8 ± 1 4.2 )mmol/L vs (1 8.9 ± 1 5.9)mmol/L ,t =2 1.48 ,P <0 0.5] .A positive relation was found between hs‐CRP count and the quantity of Troponin T(r=0 4.78 ,P0 0.5) .[Conclusion]hs‐CRP can be used in predicting the prognosis of patients with NSTE‐ACS .As an important indicator ,it also has important clinical significance in terms of treatment ,however ,hs‐CRP shows no rela‐tionship with the degree of coronary stenosis score in NSTE‐ACS patients .
