Systemic inflammatory response to acute myocardial infarction (AMI) is detrimental to heart function. In this study, we proved that poly (ADP-ribose) polymerase (PARP) activity of circulating mononuclear cell (MNC) increased significantly in post-AMI patients. MNC PARP activity was correlated positively with plasma tumor necrosis factor-alpha (TNF-alpha) level, interleukin-10 (IL-10) level and the ratio of plasma TNF-alpha/IL-10 respectively. On the contrary, MNC PARP activity was correlated negatively with left ventricular ejection fraction and left ventricular fractional shortening which were measured with echocardiography in the same day when blood sample was collected. These results implicated that activation of PARP in MNC contributes to the increases in plasma TNF-alpha and IL-10 and is associated with systolic dysfunction of heart after AMI.
