Markers of inflammation following percutaneous coronary intervention (PCI) and its effect on adverse events

Background: Number of markers of inflammation has been associated with coronary artery disease and various studies have shown increased levels during chronic stable angina, acute myocardial infarction, and percutaneous coronary intervention. However, co-relation to final outcomes of percutaneous coronary intervention with these markers has not been studied. Aim of this study was to try and find a correlation between markers of inflammation released during percutaneous coronary intervention and incidence of restenosis on follow up at 06 moths on patients undergoing percutaneous coronary intervention with Bare Metal Stent (BMS).Methods: 36 consecutive only Bare Metal Stent (BMS) angioplasties done at our centre between July 2015 and June 2016 were analysed for markers of inflammation from peripheral venous sample before the procedure and coronary sinus sample after the procedure. Pts were kept on follow up for 6 months and assessed as per their clinical symptoms and Coronary Angiogram was done where indicated and results tabulated.Results: There was increase in the studied markers of inflammation post percutaneous coronary intervention but they did not correlate with or predict possible restenosis.Conclusions: This study showed that markers of inflammation are elevated during percutaneous coronary intervention but none of these markers correlates with subsequent restenosis.
