Compared to patients with hs-cTnT within the reference limit, patients with elevated hs-cTnT more frequently had atrial fibrillation/flutter (p < 0.001), right bundle branch block (RBBB) (p = 0.026), ST segment depression (p = 0.025), T-wave inversion (p = 0.029) and LVH (p = 0.019). The gene discussed is TNNT2; the disease is atrial fibrillation.
