The incidence of ventricular arrhythmias during the monitoring period was noted as categorical data, presented as a percentage (%), and treatment comparisons were made using a chi-squared test. Post hoc analyses were performed to test for associations between two groups using a Fisher’s exact test. HR and infarct size data were distributed normally and differences between the two groups were analysed using a Student’s t-test. HR data are presented with the mean and the standard error of mean (SEM) and infarct size data are presented as box plots with median, 25th–75th percentiles (boxes) and 5th–95th percentiles (whiskers). HR data at different time-points within groups were compared using a paired Student’s t-test. Differences between results were considered to be statistically significant if the two-sided P value was < 0.05. The statistical analysis was performed using Statistical Packages for Social Sciences software (IBM SPSS 22.0.0.0 for Windows; IBM Corp, Armonk, NY, USA).
