Compared with the MI+AAV-postn-shNC+AAV-NC group, the echocardiographic results showed significantly lower EF and FS in the MI+AAV-postn-shNC+AAV-Cthrc1 group at day 28 (Figure 6B-6D;Table S8), without between-group differences in ventricular dilation parameters (LVID,s and LVID,d) (Figure 6E and 6F;Table S8). Here, CTHRC1 is linked to myocardial infarction.
