Fig. (7) Effect of vitamin D on survival after cardiac I/R. Effect of pre-treatment of vit D on survival after cardiac I/R. Survival rates over a 3-day period following cardiac I/R, 50% were demonstrated for the I/R group, and the I/R + vit D group (n = 8). Survival rates were analyzed by the Kaplan-Meier method using a log-rank test. Data are shown as mean ± SEM (n = 8 in each group); *P < 0.05 vs. Sham; **P < 0.05 vs. I/R and vehicle groups.
