Overall, when compared with that of the NOR-C group, the MVD in myocardium was significantly decreased in the TXL-H, TXL-L, and DCM-C groups (101.44 ± 7.81 versus 55.38 ± 6.74, 42.44 ± 5.03, 36.00 ± 7.15, respectively; all P < 0.01), respectively. This evidence concerns the gene TXNL1 and familial dilated cardiomyopathy.
