Killip-Kimball stage IV corresponds to cardiogenic shock. However, the Society for Cardiovascular Angiography and Interventions (SCAI) classification provides a more precise tool to classify patients according to shock severity. The aim of this study was to apply this classification to a cohort of Killip IV patients and to analyze the differences in death risk estimation between the two classifications.Methods: A single-center retrospective cohort study of 100 consecutive patients hospitalized for \u201cKillip IV AMI\u201d between 2016 and 2023 was performed to reclassify patients according to SCAI stage.Results: Distribution of patients according to SCAI stages was B=4%, C=53%, D=27%, E=16%. Thirty-day mortality increased progressively according to these stages (B=0%, C=11.88%, D=55.56%, E=87.50%; P&lt;0.001). The exclusive use of Killip IV stage overestimated death risk compared to SCAI C (35% vs. 11.88%, P=0.002) and underestimated it compared to SCAI D and E stages (35% vs. 55.56% and 87.50%, P=0.03 and P&lt;0.001, respectively). Age &gt;69 years, creatinine &gt;1.15 mg\/dl and advanced SCAI stages (SCAI D and E) were independent predictors of 30-day mortality. Mechanical circulatory support use showed an almost significant benefit in advanced SCAI stages (D and E hazard ratio, 0.45; 95% confidence interval, 0.19\u20131.06; P=0.058).Conclusions: SCAI classification showed superior death risk estimation compared to Killip IV. Age, creatinine levels and advanced SCAI stages were independent predictors of 30-day mortality. Mechanical circulatory support could play a beneficial role in advanced SCAI stages.<\/jats:p>","DOI":"10.4266\/acc.2023.01620","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T05:49:27Z","timestamp":1715665767000},"page":"257-265","update-policy":"https:\/\/doi.org\/10.4266\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Implementation
