(a–c) 2D M-mode and Doppler echocardiography were performed on rat intraperitoneal injection of saline vehicle, intraperitoneal injection of ISO for one month, and intraperitoneal injection of ISO for three months. (d) Left ventricular end-diastolic dimension (LVEDD) of rats with intraperitoneal injection of ISO for three months. (e) Ejection fraction (EF) of rats with intraperitoneal injection of ISO for three months. Data are expressed as mean ± SEM, n = 7-8; ∗P < 0.05 compared with the control group, ∗∗P < 0.01 compared with the control group.
