In the subgroup comparison, age, cardiac diseases history, and CCI did not have significant correlations with the elevated cTnI after aSAH (59.3 ± 11.2 vs. 56.8 ± 12.4, p = 0.192; 18.2 vs. 16.5, p = 0.769; 3.7 ± 2.0 vs. 3.3 ± 2.0, p = 0.193, respectively). The gene discussed is TNNI3; the disease is heart disorder.
