Lee WC, Chen TY, Chen CJ, et al. - Researchers determined the influence of complete revascularization (CR) on patients with ST-segment elevation myocardial infarction (STEMI) with Killip class ≥ III. Primary percutaneous coronary intervention (PCI) was performed from January 2008 to December 2014 on 185 patients diagnosed with STEMI with Killip class ≥ III and multiple vessel coronary artery disease. Culprit-only PCI was performed on 89 patients and immediate or staged PCI for CR was performed on the remaining 96 patients. Of 96 patients included in the CR group, 51 patients had immediate CR, and 45 had CR during the same hospitalization. They compared 30-day and 1-year clinical results between the culprit-only PCI group and the CR group and between the immediate CR group and staged CR group. Findings revealed the link of CR with a higher likelihood of post-PCI acute kidney injury, and CR did not appear to improve 30-day or 1-year clinical consequences. Better clinical outcomes were seen in patients undergoing staged CR during the same hospitalization.
