High-risk Patients in Cardiac Surgery Procedures: HiriSCORE

Plain-language summary

Over time there is a need to improve old and develop new risk models. Overall the assessment of mortality risk in cardiac surgery is performed with the use of preoperative risk models. The use of improved risk models and increased accuracy in the technique of preparing these mathematical systems does not have a positive impact on the level of prediction, which is still inaccurate, especially in the considered group of high risk. New models need to be built not only for a better prediction of mortality risk, if not also to predict morbidity in the group of patients at higher risk of complications after cardiac surgery procedures. The aim of this study is: * To construct the HiriSCORE to identify patients at higher risk of complications after cardiac surgery procedures * Assessing the impact of pre-, intra- and postoperative period to the prognosis of morbidity and mortality in high-risk patients undergoing cardiac surgery procedures.
