| Summary: | This dissertation entitled "Aortocoronary bypass surgery with or without heart-lung machine in high risk patients" is a summary of the findings of two published works by the author: Off-pump Versus On-Pump Coronary Artery Bypass Grafting Surgery in High-Risk Patients: PRAGUE-6 Trial at 30 Days and 1 Year, published in the journal Biomedical Papers in 2015 and Aspirin is insufficient in inhibition of platelet aggregation and thromboxane formation early after coronary artery bypass surgery, published in Journal of Thrombosis and Thrombolysis in 2009. The PRAGUE-6 study, which focused exclusively on patients with very high operative risk according to the EuroSCORE scoring system, confirmed the hypothesis of a higher incidence of combined endpoints up to the 30th day among patients operated with extracorporeal circulation, particularly acute myocardial infarctions. This significant difference was not maintained after one year after the surgery, mainly due to the increase in mortality between the 30th day and the 1st year in patients operated off-pump. The dissertation further discusses similar papers published on the topic in recent years, including the two very last meta- analyzes. The second part of the thesis follows the topic of myocardial revascularization in the field of antiaggregation therapy...
