However, the expression of cleaved caspase-3 in the non-myolytic left atrial myocytes of the MR AF patients (2691764.1 ± 593821.1 vs. 1621900.3 ± 39281.4, p = 0.470) and the MR sinus patients (1970992.5 ± 524326.6 vs. 1621900.3 ± 39281.4, p = 0.236) did not significantly differ from the expression of cleaved caspase-3 in the non-myolytic left atrial myocytes of the normal control subjects. The gene discussed is CASP3; the disease is miotic rate.
