Characterization of lymphocyte subpopulations and cardiovascular markers in pericardial fluid of cardiac surgery patients.

Background: Composition of pericardial fluid (PF) may reveal immunological processes influencing oxidative stress and microcirculation of different tissues of the heart and may play a role in the course of myocardial infarction, atherosclerosis, and aortic stenosis.

Patients And Methods: We investigated lymphocyte populations, cardiovascular markers and immunoglobulin composition in PF and blood samples of patients undergoing CABG operation and compared them to those who had aortic valve surgery.

Results: The amount of CD8 + T, NK, memoT and activated T-cytotoxic cells were elevated in PF compared to blood, but naiveT and activated T-helper cell ratio were lower in PF.

Five-Year Outcome after Coronary Artery Bypass Surgery in Survivors of Out-of-Hospital Cardiac Arrest.

Objective: The aim of this study was to evaluate the role of coronary artery bypass grafting (CABG) in patients with out-of-hospital cardiac arrest (OHCA).

Methods: The immediate and 5-year outcome after CABG of a consecutive series of 48 patients who survived OHCA was compared with those of control patients having had a recent myocardial infarction without ventricular arrhythmias.

Results: All OHCA patients were found to have suffered myocardial infarction-related cardiac arrest.
