Fig. 2.

Balloon inflations and enzymatic infarct size. Number of inflations (a), peak creatine kinase release in the postconditioning analogue group versus controls in the overall study group (b) and differences of median peak enzyme release with 95 % confidence intervals between study groups according to relevant patient subgroups (c). The reference for the difference is 1–3 inflations, thus, a negative difference indicates a lower peak creatine kinase in those with ≥4 inflations (c). CI confidence interval, CK creatine kinase, IPOC ischemic postconditioning, LAD left anterior descending, MVD multivessel disease, SVD single-vessel disease
