A total of 50 patients undergoing cardiac surgery with extracorporeal circulation will be randomized in two groups using a computer-generated algorithm. The first group (study group) will undergo cardiac surgery with a specialized biocompatible circuit with a hydrophilic coating, while the control group will be operated with the conventional non-coated extracorporeal circulation circuit. During the period of extracorporeal circulation, blood samples will be taken at predetermined times which will be analyzed with the ELISA technique to determine the levels of prothrombin fragments 1+2 (F1+2), thrombin/antithrombin complex (TAT) as well as platelet factor P-selectin. Moreover, sections of the circuit tubes will be examined under electron microscopy for quantitative evaluation of microthrombi detected on the walls. The expected outcome of the study is to establish, with the use of specific biochemical markers and electron microscopy the protective effect of biocompatible coated extracorporeal circulation circuits on the coagulation mechanism and platelet activation."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "maximumAge"=>"80 years", "minimumAge"=>"18 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"Inclusion Criteria:\n\n* Planned surgery\n\nExclusion Criteria:\n\n* Need for emergency surgery\n* Serious hematological condition causing anemia, thrombocytopenia, etc.\n* Receiving immunosuppressive treatment\n* Inability to obtain consent"}, "identificationModule"=>{"nctId"=>"NCT06612060", "acronym"=>"BALANCE", "briefTitle"=>"Biocompatible Versus Non-coated Extracorporeal Circuits in Cardiac Surgery", "organization"=>{"class"=>"OTHER", "fullName"=>"Aristotle University Of Thessaloniki"}, "officialTitle"=>"Comparative Randomized Study of Blood Coagulation Triggering and Thromboresistance of Biocompatible Versus Non-coated Extracorporeal Circuits During Cardiac Surgery", "orgStudyIdInfo"=>{"id"=>"BALANCE_CTS"}}, "armsInterventionsModule"=>{"armGroups"=>[{"type"=>"EXPERIMENTAL", "label"=>"Coated circuit", "description"=>"Cardiac surgery with a specialized biocompatible extracorporeal circulation circuit with a hydrophobic coating.", "interventionNames"=>["Procedure: Cardiac surgery with the use of extracorporeal circulation"]}, {"type"=>"ACTIVE_COMPARATOR", "label"=>"Non-coated circuit", "description"=>"Cardiac surgery with the conventional non-coated extracorporeal circulation circuit.", "interventionNames"=>["Procedure: Cardiac surgery with the use of extracorporeal circulation"]}], "interventions"=>[{"name"=>"Cardiac surgery with the use of extracorporeal circulation", "type"=>"PROCEDURE", "description"=>"All randomized patients will undergo open heart surgery with the use of extracorporeal circulation.
