  • Research summary

    The main objective of this exploratory study is to determine if we can identify a subset of cells within an individual’s circulating blood that could be used to identify their susceptibility to an adverse outcome after cardiac surgery, such as another heart attack. White blood cells known as monocytes are associated with the occurrence of adverse events after coronary artery bypass-graft surgery (CABG), but within an individual’s circulating blood monocytes can exist in different forms (subsets) considered good and bad. We will therefore identify and quantify the numbers of bad monocytes alongside the proteins and packages of molecules (exosomes) they release to determine if they predict outcomes after CABG surgery. Specifically, this will include major adverse cardiovascular events such as heart attack, stroke, or cardiovascular death. To address this question, we aim to analyse samples and clinical data from patients who have undergone CABG, compared to those who have undergone other cardiac procedures which are not associated with major adverse coronary artery-related events.
