Impacto de la implementación de Código Infarto en pacientes con infarto agudo de miocardio con elevación del segmento ST en el Hospital de Cardiología del Centro Médico Nacional Siglo XXI

Objective: To evaluate the impact of the implementation of the Infarction Code strategy in patients with acute myocardial infarction diagnosis. Methods: Consecutive patients with ST-elevation acute myocardial infarction ≤12 hours of evolution, were included in the infarction code strategy, before (Group I) and after (Group II). Times of medical attention and major cardiovascular events during hospitalization were analyzed. Results: 1227 patients were included, 919 men (75%) and 308 women (25%) with an average age of 62 ± 11 years. Among Group I and Group II, percutaneous coronary intervention reperfusion therapy changed (16.6% to 42.6%), fibrinolytic therapy (39.3% to 25%), and patients who did not receive any form of reperfusion therapy (44% to 32.6%; p < 0.0001). Times of medical attention decreased significantly (door-to-needle time decreased from 92 to 72 minutes, p = 0.004; door-to-balloon time decreased from 140 to 92 minutes, p < 0.0001). Kidney failure (24.6% vs. 17.9%; p = 0.006), major complications (35.3% to 29.3%), and death (21% vs. 12%; odds ratio: 0.52; 95% confidence interval: 0.38-0.71; p = 0.004). also decreased. Conclusion: The Infarction Code strategy improved treatment, times of medical attention and decreased complications and death in these patients.
