Contrast Induced Nephropathy Incidence in Patients who Underwent Primary Percutaneous Coronary Intervention Compared to those who Underwent Elective Percutaneous Coronary Intervention

Background. Percutaneous Coronary Intervention (PCI) procedure is a common intervention procedure for Acute Coronary Syndrome. One of its complications is contrast induced nephropathy (CIN). In patients who undergo primary PCI, the incidence of CIN could be higher than those who undergo elective PCI. Method. This was a prospective cohort research on patients who underwent primary PCI and elective PCI in Dr Sardjito Hospital, Yogyakarta. The incidence of CIN in subjects who underwent primary PCI was then compared with those who underwent elective PCI. Chi Square test was performed to measure the difference of CIN incidence in subjects who underwent primary and elective PCI. The risk of CIN was described as relative risk (RR) and p value < 0.05 was considered as statistically significant with 95% confidence interval. Result. There was no significant difference of CIN in subjects who underwent primary PCI compared to elective PCI (p = 0.159). Conclusion. Primary PCI was not proven to increase the risk of CIN significantly compared to elective PCI.
