MODERN MODELS OF RISK STRATIFICATION OF CARDIAC OPERATIONS

To provide more accurate stratification models, one should systematically review the figures. In 2010, there was a re-organized multicenter study team of researchers from Papworh Hospital (Cambridge, UK). The project EuroScore II involved 154 centers from 43 countries. One of three Russian centers participating in the project was the Department of Cardiac Surgery of the City Hospital N 1 named after E. E. Volosevitch, Arkhangelsk. Purpose. Participation in a multicenter study EuroScore II for development of modern models of risk stratification of cardiac operations. Methods. There were examined 113 patients over 18 y.o. operated in May-June 2010. Complicated (nonlethal) postoperative period in patients who underwent myocardial revascularization, was observed in 19.5 % of cases, heart valves replacement / repair - in 21.1 %, the combined procedure - in 45.5 %, ascending aorta and aortic arch replacement / repair - in 0 % of cases respectively. Predicted hospital mortality among the patients who underwent myocardial revascularization was 3.7 %, heart valves replacement / repair - 5.3 %, the combined procedure - 18.2 %, ascending aorta and aortic arch repair - 100 % respectively. Conclusions. Use of scale EuroScore I may become less relevant, because there is an expansion of indications for cardiac surgery, due to improved surgical techniques, anesthesia and technical equipment provision. Scale EuroScore II may allow better assessment of cardiac surgery risk.
