Interleukin-1 and tumor necrosis factor-alpha in plasma of patients with acute ischemic heart disease who undergo thrombolytic therapy: a randomized, placebo-controlled study.

In patients with acute ischemic heart disease who undergo thrombolytic therapy we have previously observed a marked endothelium-dependent activation of the coagulation system. Concomitantly the concentrations of the fast acting plasminogen activator inhibitor type 1 (PAI-1) in plasma increased. The results of recent in vitro studies would suggest that these in vivo phenomena could be associated with the procoagulant effects of the cytokines interleukin-1 (IL-1) and/or tumor necrosis factor-alpha (TNF). In the present placebo-controlled study on patients with acute ischemic heart disease treated with thrombolytic agents we observe low or undetectable concentrations, and insignificant deviations during the study periods, of IL-1 and TNF in plasma. We conclude that IL-1 and TNF play a minor role for generation of coagulant activity and systemic deviations of PAI-1 in patients who undergo coronary thrombolysis.
