超敏肌钙蛋白I检测在糖尿病心肌损伤早期诊断中的价值

目的探讨超敏肌钙蛋白I(hs-cTnI)在糖尿病心肌损伤早期诊断中的临床价值。方法选取240例2型糖尿病(T2DM)组及40例健康对照组,检测2组研究对象的糖化血红蛋白(HbA1c)、天门冬氨酸氨基转移酶(AST)、肌酸激酶(CK)、肌酸激酶同工酶(CK-MB)及hs-cTnI水平。结果 T2DM组血清hs-cTnI水平显著高于健康对照组(P0.05),血清AST、CK及CK-MB水平与健康对照组比较,差异无统计学意义(P0.05);HbA1c≥6.5%组hs-cTnI水平及升高率显著高于HBA1c≤6.4%组(P0.05),AST、CK、CK-MB水平及升高率在2组间差异无统计学意义(P0.05);T2DM组HbA1c与血清hs-cTnI呈正相关(r=0.471,P0.05)。结论 hs-cTnI诊断T2DM患者早期心肌损伤具有重要的临床价值,且hs-cTnI与HbA1c呈正相关,值得临床关注。

Value of high-sensitive troponin I detection in the diagnosis of early myocardial injury

Objective To explore the clinical value of high‐sensitive troponin I detection in the diagnosis of early myocardial inju‐ry .Methods Totally 240 type 2 diabetes mellitus (T2DM ) patients (study group) and 40 healthy people(healthy control group) were chosen as subjects .The serum level of HbA1c ,AST ,CK ,CK‐MB and hs‐cTnI were measured among the two groups ,respec‐tively .Results Hs‐cTnI level in T2DM group was significantly higher than in healthy control group(P< 0 .05) ,and AST ,CK and CK‐MB levels in two groups had no significant difference(P> 0 .05) .Hs‐cTnI level and positive rate in HbA1c ≥ 6 .5% group was significantly higher than in HbA1c ≤ 6 .4% group(P< 0 .05) ,and no significant difference of AST ,CK and CK‐MB levels and posi‐tive rate were observed in two groups(P> 0 .05) .There was a positive correlation between the level of HbA1c and that of serum hs‐cTnI in T2DM group(r= 0 .471 ,P< 0 .05) .Conclusion The hs‐cTnI level detection has important clinical value in the diagnosis of early myocardial injury in T2DM patients ,and HbA1c is positively correlated with hs‐cTnI .
