Background:

The National ST-segment elevation Acute Myocardial Infarction (ARGEN-AMI-ST) registry carried out in 2015 provided data 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 were invited to continue with the AMI registry including patients with up to 36-hour electrocardiographic STEMI evolution.

Results:

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 heart disease. Eighty-eight percent of patients underwent reperfusion, and among them, 21% received thrombolytics and 89% percutaneous coronary intervention. The delay from onset of symptoms to admission was 130 minutes (IQR 25-75: 60-305); physicians reported delays to treatment in 49% of cases, with an impact on total ischemic times (TIT). In-hospital mortality was 8.7%. In the multivariate 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 to treatment are important, especially due to the delay in patient consultation, which greatly impacts on TIT.
