概要	*Oral Presentation (English)33 ACS/AMI BACKGROUND: Peak creatine kinase-MB (CK-MB) level is associated with clinical outcomes after acute myocardial infarction (AMI). However, the prognostic impact of time between balloon and peak CK-MB (BP-time) after percutaneous coronary intervention (PCI) is unclear. METHODS: This multicentral observational study initially included 1,354 AMI patients undergoing primary PCI within 24 hours after the onset between 2011-2016. After the exclusion of patients with unknown onset time of AMI, patients with the highest CK-MB at baseline, and patients without postPCI TIMI grade 3 flow, 954 patients were ultimately enrolled. They were divided into 4 groups by BP-time with 3-hour increment. The primary endpoint was all-cause mortality. RESULTS: Kaplan-Meier analysis showed that patients with BP-time<3-hours had the lowest, and with BP-time<9-hours had the highest mortality (at 3 years: 5.5% vs. 11.6%, Figure). Multivariate Cox regression analysis revealed that BP-time was an independent predictor of all-cause mortality (HR: 1.06 (95% CI: 1.02-1.11), p=0.003). CONCLUSION: The time between balloon and peak CK-MB was associated with all-cause mortality in the primary PCI with DES era.
