Contrast-induced nephropathy in patients undergoing percutaneous coronary intervention, iso-osmolar non-ionic contrast agent versus low-osmolar ionic contrast agent

Background Coronary angiography is an advance in the management of a variety of heart conditions, but iodinated contrast injection can lead to contrast-induced nephropathy, especially in high-risk populations. There is still no consensus on the best type of contrast agent to be used. The objective of this study was to evaluate the occurrence of contrast-induced nephropathy in patients undergoing percutaneous coronary intervention, comparing a low-osmolar contrast agent with an iso-osmolar contrast agent. Methods This was a single center, longitudinal, [...]
