Echocardiographic measurements of HSPB7 CKO and control mice.

(A) Representative two-dimensional and M-mode echocardiographic images of the HSPB7 CKO and control hearts. (B) Echocardiographic analysis in the HSPB7 CKO and control mice before and at 4 days (d4) and 7 days (d7) after tamoxifen administration. Left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end-systolic internal diameter (LVIDs), and left ventricular end-diastolic internal diameter (LVIDd). Data are means ± SD; n = 5 per group. *, P < 0.05 **, P < 0.01 relative to the control.
