Abstract
Interleukin-1 (IL-1) is the prototypical pro-inflammatory cytokine that occupies an apical place in the inflammatorycascade and also modulates cardiac function, functioning as a soluble cardiodepressant factor. Preclinical research over the past 4 decades has shown that blocking IL-1 processing or activity favorably affects cardiomyocyte survival and cardiac function in experimental animal models, paving the way for clinical studies in patients with heart disease. The promising results of phase II clinical trials of IL-1 blockade in patients with acute myocardial infarction and heart failure have been followed by a successful phase III trial in patients with prior acute myocardial infarction. Three IL-1 blockers with different mechanism of action are currently available for clinical use, although currently none have an indication for heart disease. We herein review the bench-to-bedside clinical translation of IL-1 targeting strategies and discuss the potential use of IL-1 blockade in patients with heart disease.
