Moving Forwards by Blocking Back-Flow: The Yin and Yang of MI Therapy

Circ Res. 2016 Mar 4;118(5):898-906. doi: 10.1161/CIRCRESAHA.115.306569.


Mitochondrial reactive oxygen species production has emerged as an important pathological mechanism in myocardial ischemia/reperfusion injury. Attempts at targeting reactive oxygen species by scavenging using antioxidants have, however, been clinically disappointing. This review will provide an overview of the current understanding of mitochondrial reactive oxygen species in ischemia/reperfusion injury. We will outline novel therapeutic approaches designed to directly target the mitochondrial respiratory chain and prevent excessive reactive oxygen species production and its associated pathology. This approach could lead to more effective interventions in an area where there is an urgent need for new treatments.

Keywords: antioxidants; mitochondria; oxygen; reactive oxygen species; reperfusion injury.
