A total of 17 heart attack code programs have been compared in terms of incidence rate, clinical characteristics, reperfusion therapy, delay to reperfusion, and 30-day mortality. Methods: National prospective observational study (83 centers included in 17 infarction networks). The recruitment period was 3 months (April 1 to June 30, 2019) with clinical follow-up at 30 days. Results: 4366 patients with STEMI were included. The incidence rate was variable between different AC (P < .0001), as was gender (P = .003) and the prevalence of cardiovascular risk factors (P < .0001). Reperfusion treatment was primary angioplasty (range 77.5%-97.8%), fibrinolysis (range 0%-12.9%) or no treatment (range 2.2%- 13.5%). The analysis of the delay to reperfusion showed significant differences (P < .001) for all the intervals analyzed. There were significant differences in 30-days mortality that disappeared after adjusting for clinical and healthcare network characteristics. Conclusions: Large differences in STEMI care have been detected between the different AC, in terms of incidence rate, clinical characteristics, reperfusion treatment, delay until reperfusion, and 30-day mortality. The differences in mortality disappeared after adjusting for the characteristics of the patient and the care network.engVoRhttp://creativecommons.org/licenses/by-nc-nd/4.0/Attribution-NonCommercial-NoDerivatives 4.0 Internacional52118-12810.24875/RECICE.M22000360REC: interventional cardiology (English Edition)open access2-s2.0-85172018384L2026887831
