Detailed Description:

Percutaneous coronary intervention (PCI) has become the most common form of coronary revascularization worldwide. Although PCI is a safe procedure, it may have multiple risks including bleeding, coronary dissection, abrupt vessel closure, and myocardial necrosis. It is estimated that approximately 25% of patients undergoing PCI have significant postprocedural creatinine kinase (CK)/creatinine kinase myocardial band (CK-MB) elevations and approximately 50% of patients have significant post-procedural troponin elevations. Initially, it was felt these elevations were simple enzyme leaks with no long-term implications.

Now, several studies have demonstrated that periprocedural infarction is associated with short-, intermediate-, and long-term adverse outcomes, most notably mortality. Pretreatment with antiplatelets such as aspirin and clopidogrel play an important role in reducing cardiovascular events (CV events) following PCI.

Omega -3 polyunsaturated fatty acids (PUFAs) have antiplatelet effect. It may also improve response to aspirin and clopidogrel in low-response patients.

This study is a randomized clinical trial (RCT) evaluating the effect of omega 3 supplement [with 400mg Eicosapentaenoic acid (EPA) and 200mg docosahexanoic acid (DHA)] on biomarkers of cardiac necrosis (CKMB and troponin I) in patients undergoing elective PCI. Eighty patients planed to do elective PCI will be categorized into two groups. The first group will be received standard regimen for PCI (aspirin, clopidogrel, and heparin) and the second group will be treated with standard regimen in addition to 3 gram omega 3 (12 hours before PCI). Blood samples will be drawn in all patients before and 8 and 24 h after intervention for cardiac biomarkers assessment (CK-MB, troponin I)and inflammation marker C-reactive protein (CRP). Major adverse cardiac events (MACE) will be evaluated as a second endpoint.
