title: Cytokines in acute coronary syndromes.
abstract: The aim of this study was to show the presence of an imbalance between pro-inflammatory and anti-inflammatory mediators in patients affected by acute coronary syndromes (ACS). We evaluated the production in cultured and stimulated lymphomonocytes of interferon (IFN)gamma and tumor necrosis factor (TNF)alpha, which are well known to possess pro-inflammatory effects, and of interleukin (IL)10, which has been shown to have a protective anti-inflammatory activity, in two groups of 30 patients affected by acute myocardial infarction (AMI) and unstable angina (UA), compared with two equivalent groups of patients with stable angina (SA) and of healthy volunteers. We found a significant increase of IFNgamma and TNFalpha production (p<0.01) and a significant decrease of IL-10 production (p<0.01) in cultures of lymphomonocytes taken from patients with AMI and UA compared with SA patients and controls. No significant changes were found between AMI and UA patients and SA patients and controls. We conclude that a relevant imbalance in cytokine release is present in ACS, markedly favoring pro-inflammatory effects.
