Differences in Plasma Extracellular Vesicles of Different Origin in On-Pump Versus Off-Pump Cardiac Surgery.

Coronary artery bypass grafting (CABG) using cardiopulmonary bypass (CPB) causes a systemic inflammatory response that can worsen patient outcomes. Off-pump surgery has been associated with a reduced inflammatory response. The precise mechanisms and the role of extracellular vesicles (EVs) in this context are not fully understood.

Aortic Graft at Coronary Artery Bypass Surgery as a Source of Human Aortic Smooth Muscle Cells.

One of the serious obstacles of the aortopathies research is a considerable shortage of human aortic smooth muscle cells (SMCs), which can be used to model the disease. SMC in most cases come from the whole aorta of transplant donors, which are rather difficult to access. In the course of coronary artery bypass graft (CABG) surgery, a fragment of aortic tissue is excised to make a bypass root.

[Cognitive dysfunction and content of inflammatory markers in patients after coronary artery bypass graft].

Aim: To study the relationship between the content of inflammatory biomarkers and cognitive function in patients after coronary artery bypass graft (CABG) performed in condition of artificial blood circulation (ABC) or open-heart surgery (OHS).

Material And Methods: Twenty-nine patients with ischemic heart disease who survived CABG, mean age 62.4±6.

New technique of local ischemic preconditioning induction without repetitive aortic cross-clamping in cardiac surgery.

Background: Several studies have demonstrated that local ischemic preconditioning can reduce myocardial ischemia-reperfusion injury in cardiac surgery patients; however, preconditioning has not become a standard cardioprotective intervention, primarily because of the increased risk of atheroembolism during repetitive aortic cross-clamping. In the present study, we aimed to describe and validate a novel technique of preconditioning induction.

Methods: Patients undergoing coronary artery bypass grafting (12 women and 78 men; mean age, 56 ± 11 years) were randomized into 3 groups: (1) Controls (n = 30), (2) Perfusion (n = 30), and (3) Preconditioning (n = 30).
