Figure 4

Developed contractile stress of right atrial trabeculae from all patients (A and B), separately from males (C and D) and from females (E and F) with remote ischemic preconditioning (RIPC; black symbols) and with placebo (white symbols) during baseline, hypoxia, reoxygenation, and exposure to isoproterenol, without (A, C, E) and with (B, D, F) normalization to baseline, respectively. Data are presented as mean±SEM. Differences between RIPC and placebo were analyzed by 2‐way (group, time) repeated‐measures ANOVA followed by Fisher's least significant difference test. *P<0.05, RIPC vs placebo.
