Why the study?
This study aimed to investigate if remote ischemic preconditioning reduces the inflammatory process in patients undergoing CABG.
Does remote ischemic preconditioning reduce inflammation markers and myocardial injury in adult patients undergoing elective coronary artery bypass grafting?
Does remote ischemic preconditioning reduce inflammation markers and myocardial injury in adult patients undergoing elective coronary artery bypass grafting?
Remote ischemic preconditioning prior to CABG significantly reduces systemic proinflammatory markers (IL-1 and IL-6) but does not provide direct cardioprotection as measured by high-sensitivity troponin I.
Background: This study aimed to investigate if remote ischemic preconditioning reduces the inflammatory process on patients undergoing coronary artery bypass grafting (CABG). Methods: We conducted a case-control study involving 80 patients, half of whom underwent ischemic preconditioning for severe coronary artery disease (CAD) and subsequently underwent CABG. We assessed interleukin (IL)-1 and IL-6 levels using the enzyme-linked immunosorbent assay (ELISA) method, high-sensitivity troponin I (hsTnI) using chemiluminescent immunoassay (CLIA), and C-reactive protein (CRP) using the turbidimetric method at three key time points: before surgery (visit 1 or V1), immediately postoperatively (visit 2 or V2), and 1 week postoperatively (visit 3 or V3) in all subjects. Results: Ischemic preconditioned patients showed a significant decrease in proinflammatory markers (IL-1, IL-6) but not in CRP or hsTnI. Conclusions: , as evidenced by the absence of a statistically significant decrease in hsTnI level.
