ABSTRACT
Objective:
To investigate the relationship between serum levels of high sensitivity cardiac troponin T (hs-cTnT) and the severity of coronary lesions in patients with stable coronary artery disease (SCAD).Methods:
A total of 450 SCAD patients with coronary angiography (CAG) conifrmed diagnosis in our hospital were studied, and serum levels of hs-cTnT were examined at 3 days prior CAG in all patients. Based on tertiles of Gensini score, the patients were divided into 3 groups Low score group,n=153 patients with Gensini score28. The relationships between Gensini score and hs-cTnT levels were analyzed among 3 groups. The optimal cut-off value of hs-cTnT for predicting high Gensini score and the need of revascularization were studied by ROC curve, the relationships between hs-cTnT and high Gensini score, the need of revascularization were further detected by Logistic regression analysis.Results:
The median values (25%-75%) of hs-cTnT in Low score group, Intermediate score group and High score group were 6.72 (4.20, 8.93) pg/ml, 7.90 (5.74, 12.68) pg/ml and 14.99 (10.26, 24.30) pg/ml respectively, allP<0.01. ROC curve analysis indicated that the area under curve (AUC) of hs-cTnT for predicting high Gensini score was 0.837 (95% CI 0.803-0.874), for the need of revascularization was 0.772 (95% CI 0.728-0.817); the best cut-off value of hs-TnT for predicting high Gensini score was 10.04 pg/ml and for the need of revascularization was 8.56 pg/ml. Logistic regression analysis suggested that with adjusted age, gender, the history of hypertension, diabetes, smoking, blood levels of creatinine, LDL-C and hs-CRP, hs-cTnT was still an independent predictor for high Gensini score (OR=1.13, 95% CI 1.06-1.20,P<0.001) and for the need of revascularization (OR=1.19, 95% CI 1.14-1.24,P<0.001).Conclusion:
Serum level of hs-cTnT has been related to severity of coronary lesions in SCAD patients, hs-cTnT might be used as one of the pre-operative predictor for severe coronary disease and for the need of revascularization.
