Acute Myocardial Infarction in Argentina. Third ARGEN-IAM-ST Registry Report and 8-Year Mortality Behavior

pp. 415-422

Abstract

Background: The continuous Argentine ST-segment Elevation Acute Myocardial Infarction (ARGEN-IAM-ST) registry presents its third general report.

Objective: The aim of this study was to evaluate the main ST-segment elevation myocardial infarction (STEMI) markers of care and its complications in the continuous ARGEN-IAM-ST registry, and assess the outcome of reperfusion therapy and mortality in the last 8 years.

Methods: This was a national, prospective, multicenter study, including STEMI patients with up to 36-hour evolution.

Results: A total of 6765 patients, mean age 61±12 years, 65% male , were included in the study. A significant burden of cardiovascular risk factors was observed: 58 % of patients had hypertension, 23 % diabetes, 42 % dyslipidemia, 37 % were active smokers, and 17% had a family history of cardiovascular disease. In 13.5 % of cases, patients had prior history of coronary heart disease. On admission, 49 % presented with anterior AMI and 23% with heart failure. Median (interquartile range, IQR) pain-consultation time was 120 minutes (IQR 60-285), door-to-needle time 50 minutes (IQR 25-110) and door-to-balloon
time 100 minutes (IQR 58-190) Overall in-hospital mortality was 8.8 %. An exploratory and descriptive analysis was performed to assess the variation in reperfusion and mortality over 8 years, showing no marked changes in mortality despite high reperfusion rates.
Conclusion: In the last 8 years, the mortality recorded in the ARGEN-IAM-ST registry has remained at high values despite the high reperfusion rates reported.
