Infarto agudo de miocardio con elevación del segmento ST en la Argentina. Datos del registro continuo ARGEN-IAM-ST

Background: The National ST-segment elevation Acute Myocardial Infarction (ARGEN-AMI-ST) registry carried out in 2015 provideddata on the reality of AMI in Argentina.Objective: The aim of this study was to present an updated report of the ARGEN-AMI-ST registry.Methods: This was a national, prospective, multicenter study. After the first phase of the ARGEN-AMI-ST survey, centers wereinvited to continue with the AMI registry including patients with up to 36-hour electrocardiographic STEMI evolutionResults: The analyzed population comprised 2,464 patients assisted in 78 centers. Mean age was 60±12 years and 80% were men.Preventable risk factors were: 45% smoking, 58% hypertension, 24% diabetes, 41% dyslipidemia and 11% history of coronary heartdisease. Eighty-eight percent of patients underwent reperfusion, and among them, 21% received thrombolytics and 89% percutaneouscoronary intervention. The delay from onset of symptoms to admission was 130 minutes (IQR 25-75: 60-305); physiciansreported delays to treatment in 49% of cases, with an impact on total ischemic times (TIT). In-hospital mortality was 8.7%. In themultivariate analysis, being treated in a center with hemodynamic availability was not independently associated with survival.Conclusions: Current data from the continuous AMI registry in Argentina are similar to those shown in the 2015 survey. Delays totreatment are important, especially due to the delay in patient consultation, which greatly impacts on TIT.
