Given the limited number of outcome events, Firth's penalized logistic regression identified factors independently associated with survival to discharge and favorable neurological outcomes (cerebral performance category 1\u20132).Results: Of 5,026 patients treated by emergency medical services, 371 underwent CAG; 258 (69.5%) had non-STE, and 105 (40.7%) of these underwent PCI and formed the cohort. Sixty-nine (65.7%) survived to discharge, and 55 (52.4%) had favorable neurological outcomes. Initial shockable rhythm (adjusted odds ratio [aOR], 5.38; 95% confidence interval [CI], 1.77\u201318.02), prehospital return of spontaneous circulation (ROSC) (aOR, 10.30; 95% CI, 3.62\u201333.06), and shorter scene time interval (aOR, 0.88 per minute; 95% CI, 0.79\u20130.98) were independently associated with survival. Initial shockable rhythm (aOR, 11.02; 95% CI, 3.39\u201343.00) and prehospital ROSC (aOR, 11.69; 95% CI, 3.69\u201345.03) were independently associated with favorable neurological outcomes.Conclusion: Among patients with non-STE OHCA undergoing CAG and PCI, initial shockable rhythm and prehospital ROSC were associated with both outcomes, and shorter scene time interval with survival only. As the cohort was restricted to patients who survived to undergo PCI, these findings reflect prognostic stratification and cannot infer benefit from CAG or PCI.<\/jats:p>","DOI":"10.12701\/jyms.2026.43.62","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T05:22:28Z","timestamp":1788499348000},"page":"62","update-policy":"https:\/\/doi.org\/10.12701\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Shockable
