Peroxisome proliferation-activated receptor-γ (PPAR-γ) is a ligand-activated transcription factor belonging to the nuclear hormone receptor superfamily and participates in the regulation of various metabolic pathways as well as inflammatory responses. PPAR-γ ligands significantly improve myocardial functional recovery and prevent ischemia-reperfusion induced injury. Given the increasing understanding of the cardioprotective effects of PPAR-γ ligands, we know today that the therapeutic effects of PPAR-γ ligands reach far beyond their use as insulin-sensitizers, as many of these agents exert beneficial effects in the conditions associated with ischemia-reperfusion and inflammation.
