To Compare the Ischemic Pre-Conditioning and Post-Conditioning on Reperfusion Injury in Humans. - Full Text View

Purpose

Reperfusion Injury occurs by the sudden blood flow to the injured and ischemic myocardium during restoration of blood flow either by Mechanical revascularization or thrombolysis. A phenomenon known as Pre-conditioning has been identified to limit the the extent and severity of reperfusion injury but it is very difficult to apply it in patient care setting as timing of acute cardiac or neurologic ischemic event is difficult to reliably predict.

Postconditioning or ischemic postconditioning is well known to attenuate the reperfusion injury. There is enough data that shows the benefit of post conditioning in reducing the reperfusion injury in animals. However postconditioning in humans has not been investigated.

We hypothesize that Post conditioning will attenuate the reperfusion injury and will be comparable to the effect of preconditioning in humans.

5. Do not have family history defined as a parent or sibling with coronary disease diagnosed before age 40. .

Exclusion Criteria:

Patients with significant medial illness for which they are receiving continued monitoring or treatment, known cardiovascular disease, or risk factors for coronary artery disease are excluded. These risk factors include
1. Smoking
2. Hyperlipidemia defined as and LDL>180, HDL<30, TG>200 or LDL/HDL>6.0
