The cardiac functions were assessed by cMRI at the normal condition, at the 4th week after the operation, and after acupuncture. Data are expressed as mean ± SEM (the PC6 group, n = 4, two in the PC6 group were failed to collect the cMRI data completely; the ST36 group, n = 5). ^■P < 0.05 and ^■■P < 0.01, compared with their separate baselines of the same group, respectively (P = 0.008, the LVEDV of the ST36 group; P = 0.024, the LVESV of the PC6 group; P = 0.043, the LVESV of the ST36 group; P = 0.017, the LVEF of ST36 group after acupuncture). Data of LVEF, LVEDV, and LVESV of PC6 group were analyzed by t-test, and LVESV of ST36 group was analyzed by Wilcoxon signed-ranks. ^△P < 0.05, compared with that of the PC6 group after acupuncture. The left ventricular wall mass of the ST36 group was significantly greater than that of the PC6 group (P = 0.030). Data were analyzed by t-test.
