Abstract
INTRODUCTION AND OBJECTIVES: A substantial proportion of patients experiencing ST-segment elevation myocardial infarction (STEMI) have a late presentation. There is a lack of temporal trends drawn from large real-word scenarios in these patients. METHODS: All STEMI patients included in the AMIS Plus registry from January 1997 to December 2017 were screened and patient-related delay was assessed. STEMI patients were classified as early or latecomers according to patient-related delay (≤ or> 12hours, respectively). RESULTS: A total of 27 231 STEMI patients were available for the analysis. During the study period, the prevalence of late presentation decreased from 22% to 12.3% (P <.001). In latecomer STEMI patients, there was a gradual uptake of evidence-based pharmacological treatments (rate of P2Y12 inhibitors at discharge, from 6% to 90.6%, P <.001) and a marked increase in the use of percutaneous coronary intervention (PCI), particularly in 12- to 48-hour latecomers (from 11.9%-87.9%; P <.001). In-hospital mortality was reduced from 12.4% to 4.5% (P <.001). On multivariate analysis, PCI had a strong independent protective effect on in-hospital mortality in 12- to 48-hour latecomers (OR, 0.29; 95%CI, 0.15-0.55). CONCLUSIONS: During the 20-year study period, there was a progressive reduction in the prevalence of late presentation, a gradual uptake of main evidence-based pharmacological treatments, and a marked increase in PCI rate in latecomer STEMI patients. In-hospital mortality was reduced to a third (to an absolute rate of 4.5%); in 12- to 48-hour latecomers, this reduction seemed to be mainly associated with the increasing implementation of PCI.
