Our objective was to assess the impact of hs-cTnT elevation on functional outcome and mortality in AIS patients with large vessel occlusion (LVO) in the anterior circulation 3 months after ET and explore factors affecting hs-cTnT elevation. A total of 143 consecutive AIS patients with large vessel occlusion (LVO) in the anterior circulation following ET in a single stroke center were enrolled between January 2015 and November 2017. Hs-cTnT was quantitated on admission. Demographic characteristics, clinical data, functional outcome and all-cause mortality were compared between patients with elevated hs-cTnT levels (>14 ng/L) and those with normal hs-cTnT levels (≤14 ng/L). 58/143(40.6%) patients showed elevated hs-cTnT levels before ET. Factors independently associated with hs-cTnT elevation were admission NIHSS score (OR = 1.08, 95% CI 1.01-1.16, p = 0.032), coronary heart disease (OR = 4.89, 95% CI 1.82-13.11, p = 0.002) and congestive heart failure (OR = 4.10, 95% CI 1.07-15.68, p = 0.039). In the univariate analysis, patients with elevated hs-cTnT levels were at significantly higher risk of 3-month poor outcome (p = 0.029) and mortality (p < 0.001) than those with normal hs-cTnT levels. After multivariable analysis, hs-cTnT elevation remained an independent predictor of 3-month mortality (OR = 4.49, 95% CI 1.68-11.98, p = 0.003). In this cohort of AIS patients with LVO in the anterior circulation undergoing ET, hs-cTnT elevation is an independent predictor of 3-month mortality. Admission NIHSS score, coronary heart disease and congestive heart failure are independently associated with elevated hs-cTnT levels.
