Correlation Study Between Atrial Fibrillation and High-sensitivity Cardiac Troponin T Level in Patients With Stable Coronary Artery Disease / 中国循环杂志

ABSTRACT

Objective: To explore the relationship between serum level of high-sensitivity cardiac troponin T (hs-cTnT) and atrial ifbrillation (AF) occurrence in patients with stable coronary artery disease (CAD). Methods: A total of 1011 patients with stable CAD treated in our hospital from 2013-01 to 2015-09 were retrospectively studied. According to quartiles of hs-cTnT, the patients were divided into 4 groups Group① the patients with hs-cTnT≤7ng/L, n=283, Group② hs-cTnT 7-10ng/L,n=238, Group③ hs-cTnT 10-15ng/L,n=272 and Group④ hs-cTnT>15ng/L,n=218. The relationship between hs-cTnT level and AF occurrence rate was studied; the risk factors for AF occurrence were explored by multi stepwise Logistic regression analysis. Results: There were 127/1011 (12.6%) patients combining AF and 884 (87.4%) with simple type stable CAD. AF patients had the higher serum level of hs-cTnT than non-AF patients 17.0 (12.0, 25.0) ng/L vs 10.0 (7.0, 13.0) ng/L,P Conclusion: Increased serum level of hs-cTnT was closely related to AF occurrence in patients with stable CAD.
