Abstract:Objective To study the clinical value of serum CTRP3 and CTRP9 in acute ischemic stroke (AIS). Methods We selected 85 patients with AIS (diagnosed within 24 h) as subjects of observation group, and meanwhile, 80 healthy subjects as control group. Serum CTRP3 and CTRP9 were measured and compared between these 2 groups. Logistic regression model was implemented to fit the joint diagnosis. And the diagnostic value of each index was analyzed by the working characteristic curve of the subjects. Results The serum CTRP3 and CTRP9 in control group were higher than those in observation group (P < 0.05). At the cut-off value as 295.22 ng/ml, the sensitivity, specificity and 95%AUC of CTRP3 were 76.47% (95% CI: 0.658, 0.847), 78.75% (95% CI: 0.679, 0.868), 0.803 (95% CI: 0.751, 0.854), respectively. While the cut-off value of CTRP9 is 282.15ng/ml, the sensitivity, specificity and 95%AUC were 74.12% (95% CI: 0.633, 0.827), 88.75% (95% CI: 0.792, 0.944), 0.763 (0.710, 0.816), respectively. The sensitivity, specificity and 95%AUC of joint diagnostic model were 81.18% (95% CI: 0.709, 0.885), 76.25% (95% CI: 0.652, 0.847), 0.870 (0.832, 0.908), respectively, which were evidently higher than them of CTRP3 and CTRP9. Meanwhile, the AUC of joint diagnosis (0.870) were also higher than them of CTRP3 (0.803) and CTRP9 (0.763). Conclusion Serum CTRP3 and CTRP9 are evidently related to AIS and their joint diagnosis could provide helpful support for the timely diagnosis of AIS.
