High-Sensitivity Cardiac Troponin I and T Response Following Strenuous Activity is Attenuated by Smokeless Tobacco: NEEDED (North Sea Race Endurance Exercise Study) 2014.

ABSTRACT: Background Use of snus, a smokeless tobacco product, is increasing in Scandinavia. Strenuous physical activity is associated with an acute increase in high-sensitivity cardiac troponin (swhs-cTn) concentrations. Current smoking is associated with lower hs-cTn, but whether this also holds true for smokeless tobacco and whether tobacco affects the hs-cTn response to exercise remain unknown. Methods and Results We measured hs-cTnI and hs-cTnT concentrations in 914 recreational athletes before and 3 and 24 hours after a 91-km bicycle race. Self-reported snus tobacco habits were reported as noncurrent (n=796) and current (n=118). The association between snus use and change in log-transformed hs-cTnI and hs-cTnT concentrations (ie, the differences between concentrations at baseline and 3 hours a
