Comparison in the parameters of cardiac function between DCM and SMC groups. Four weeks after transplantation of BMSCs, ultrasonography showed that, compared with SMC group, heart muscles in DCM group became significantly thickened and the diastolic and systolic functions were apparently impaired. Statistical analysis showed that there were significant differences in LVDD, LVPW, LVFS, IVSD, EF between the two groups (A, B). Hemodynamic studies revealed that there were statistically significant differences in the parameters of cardiac function between the two groups (*P < 0.05). In DCM group, the cardiac function continue to worsen while the heart function in the DCM group was improved (D-F) (**P < 0.01). Analysis also exhibited that cardiac index was significantly higher in DCM group than in SMC group (*P < 0.001) (C).
