The model was derived from a training dataset of 336,433 PCI cases carried out between 2007 and 2011 in England and Wales, with 30 day mortality provided by record linkage. All patients except those requiring pre PCI ventilation were included. Procedures in 2012 were used to perform temporal validation of the model. The strongest predictors of 30-day mortality were cardiogenic shock, dialysis, the indication for PCI and the degree of urgency with which it was performed. The model had an area under the receiver operator characteristic curve of 0.85 on the training data and 0.86 on validation. Calibration plots indicated a good model fit on development which was maintained on validation.
