Overview

Ischemia reperfusion injury is a complex disorder associated with various cardiovascular and other risk factors mainly including Hypertension, hyperlipidemia, Diabetes, Insulin resistance, aging, and defects with coronary artery circulation. Although the exact mechanism about how these causes injuries are still not clear but studies have done so far best explains their role in mediating oxidative stress and endothelial cell dysfunctions, the two most important pathophysiological processes involved in the mediation of injury[1].

Risk Factors

Risk factors for reperfusion injury include

It is important to identify the risk factors associated with worse reperfusion injury in STEMI patients. This may help in early risk stratification and develop therapeutic targets to reduce the infarct size associated with reperfusion injury. These risk factors also increase the risk of a first cardiac event and emphasize the importance of secondary prevention. Most of these associations are based on animal studies and includes:
