Previous studies comparing on-pump and off-pump operating strategy did only partially demonstrate benefits of the off-pump myocardial revascularisation.In primary end-points (MI, death, renal failure, and so on) there was no significant difference, but in secondary end-points we observed benefits resulting for patients. We would like to show the benefit of the method without extracorporeal circulation in patients with higher and hight operation risk, coming from EuroSCORE classification system (6 points and more).

Condition Intervention
Ischemic Heart Disease
Post-Operative Complications

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
