Compared to non-obese patients, overweight and obese individuals have similar early mortality rate following CABG. This study can substantiate the presence of obesity paradox only in terms that elevated BMI patients have comparable outcome with non-obese. Further research is needed to delineate potential underlying mechanisms that set off obesity to protective factor for coronary surgery.

The number of CABG increases despite the enlargement of PCI. The risk for isolated CABG given by EuroSCORE increases over years. The risk factors, significantly contributing to higher EuroSCORE are: older age, extracardiac arteriopathy, recent myocardial infarction and emergency operation.

In this study involving low risk patients, a PCI prior to CABG did not increase morbidity or mortality.

The EuroSCORE II might be considered a solid predictive tool for hospital mortality. Although, the EuroSCORE II employs more sophisticated calculation methods regarding the number and definition of risk factors included, it does not seem to significantly improve the performance of previous iterations.
