Abstract:
Objective To detect the change and clinical significance of homocysteine (Hcy),hypersensitivity C response protein (hs-CRP) and hypersensitivity troponin I (hs-TnI) in patients with acute myocardial infarction (AMI).Methods Ninety-six cases of AMI were selected as the research group and 60 cases of coronary heart disease without AMI were enrolled in the control group.Blood samples were collected to measure the contents of serum Hcy,hs-CRP and hs-TnI.ROC curve was drawn and Logistic regression model was established to analyze the role of each index alone and combined detection in the diagnosis of AMI.Results The levels of Hcy,hs-CRP and hs-TnI in the research group were significantly higher than those in the control group (Hcy: (29.29±7.65) mol/L vs.(17.23±4.68) mol/L;hs-CRP: (15.47±5.01) mg/L vs.(9.21±3.15) mg/L;hs-TnI: (40.88±9.18) ng/mL vs.(7.34±2.12) ng/mL,t=2.78,8.66,34.36,P<0.05).The area under the ROC curve of Hcy,hs-CRP,hs-TnI were 0.802 (95%CI(0.729~0.874)),0.71(95%CI(0.62~0.792)),0.929 (95%CI(0.891~0.967)),respectively.The area under the combine detection curve was 0.971 (95%CI,0.950~0.992).The sensitivity of Hcy,hs-CRP and hs-TnI in the diagnosis of AMI were 79%,57%,87%,respectively,the specificity of the three groups were 72%,70%,90%,the sensitivity and specificity of combined detection were 96% and 88%.Conclusion Combined detection of Hcy,hs-CRP and hs-TnI plays a better role in the diagnosis of AMI than that of Hcy,hs-CRP,hs-TnI alone and has a high specificity and sensitivity in the diagnosis of AMI.
