Subgroup analyses of the STICH trial suggest that patients with less dilated LV and better LVEF may benefit from SVR, while those with larger LV and poorer LVEF may do worse. Clinical Trial Registration #: NCT00023595.
Recently, inflammation has been considered as a risk factor of postoperative atrial fibrillation (PAF). The main purpose of this study was to estimate the connections between occurrence of PAF and cytokine release. Thirty-three patients who qualified for cardiopulmonary bypass graft (CABG) were included in the study. Blood was taken from all of them before CABG, then 3 h, 24 h, and 72 h afterwards. Cytokine (IL-6, IL-2, IL-4, IL-10, IFN-gamma, TNF-alpha) concentration was measured at every time point. Eleven patients developed atrial fibrillation after the CABG. Five of them developed PAF until 1 day post-CABG and six of them after 1 day post-CABG. Patients who developed PAF before 1 day post-CABG were characterized by a higher level of IL-2 in sera before 24 h and 72 h post-CABG compared with patients without PAF. Moreover, the PAF before 1 day post-CABG group was also characterized by the higher level of IFN-gamma and IL-10 at 24 h after intervention. Analysis of patients who developed PAF after 1 day post-CABG revealed a higher level of IL-10 and IFN-gamma at 24 h post-CABG compared with patients without PAF. In this study, we have shown for the first time a straightforward connection between IL-2 sera levels and the development of PAF shortly after CABG.
This study highlights the importance of extracellular nucleotides and adenosine metabolism in the atherosclerotic vessel in both experimental and clinical setting. The increased eADA activity marks an early stage of atherosclerosis, contributes to its progression and could represent a novel target for therapy.
(1) Atrial fibrillation is a common postoperative complication after myocardial revascularization procedures which prolongs ICU stay. (2) The study did not show that the incidence of postoperative AF is influenced by the technique of coronary artery bypass grafting: with or without CPB. (3) The prevalence of postoperative AF increase when CABG is combined with valve replacement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
