RESUMEN
BACKGROUND: ST-segment-elevation myocardial infarction (STEMI) and non-ST-segment-elevation myocardial infarction (NSTEMI) management has evolved considerably over the past 2 decades. Little information on mortality trends in the most recent years is available. We assessed trends in characteristics, treatments, and outcomes for acute myocardial infarction in France between 1995 and 2015. METHODS: We used data from 5 one-month registries, conducted 5 years apart, from 1995 to 2015, including 14 423 patients with acute myocardial infarction (59% STEMI) admitted to cardiac intensive care units in metropolitan France. RESULTS: From 1995 to 2015, mean age decreased from 66±14 to 63±14 years in patients with STEMI; it remained stable (68±14 years) in patients with NSTEMI, whereas diabetes mellitus, obesity, and hypertension increased. At the acute stage, intended primary percutaneous coronary intervention increased from 12% (1995) to 76% (2015) in patients with STEMI. In patients with NSTEMI, percutaneous coronary intervention ≤72 hours from admission increased from 9% (1995) to 60% (2015). Six-month mortality consistently decreased in patients with STEMI from 17.2% in 1995 to 6.9% in 2010 and 5.3% in 2015; it decreased from 17.2% to 6.9% in 2010 and 6.3% in 2015 in patients with NSTEMI. Mortality still decreased after 2010 in patients with STEMI without reperfusion therapy, whereas no further mortality gain was found in patients with STEMI with reperfusion therapy or in patients with NSTEMI, whether or not they were treated with percutaneous coronary intervention. CONCLUSIONS: Over the past 20 years, 6-month mortality after acute myocardial infarction has decreased considerably for patients with STEMI and NSTEMI. Mortality figures continued to decline in patients with STEMI until 2015, whereas mortality in patients with NSTEMI appears stable since 2010.

BACKGROUND: The FAST-MI programme, consisting of 1-month surveys of patients admitted to hospital for acute myocardial infarction (AMI) in France, has run since 2005. AIM: To gather data on the characteristics, management and outcomes of patients hospitalized for AMI at the end of 2015 in France and to provide comparisons with the previous surveys. METHODS: Consecutive adults with ST-segment elevation myocardial infarction (STEMI) or non-ST-segment-elevation myocardial infarction (NSTEMI) with symptom onset≤48hours were included over a 1-month period, with a possible extension of recruitment for 1 additional month. Patients with AMI following cardiovascular procedures were excluded. In all, 204 centres participated in the survey (114 community hospitals, 40 academic, 48 private clinics, 2 army hospitals), representing 78% of French centres managing AMI patients. Inclusion started from 5 October 2015. Data were collected on-site from source files by external research technicians, using an electronic case record form with automatic quality checks. Centralized biology was organized in voluntary centres to collect RNA and DNA samples, serum and stools. Long-term follow-up was organized centrally with interrogation of municipal registry offices, physicians and by direct contact with the patients or their families. RESULTS: A total of 5291 patients were included over the entire recruitment period, with 3813 included during the first month (STEMI: 49%, NSTEMI: 51%). Mean age was 66±14 years, 29% were≥75 years of age, 28% were women; 80% presented with typical chest pain. In STEMI patients, 6% received intravenous fibrinolysis and 71% underwent primary PCI. The hospital death rate was 2.7% (STEMI: 2.8%, NSTEMI: 2.5%). CONCLUSIONS: Recruitment was in line with expectations and the first data show that management has continued to evolve since the 2010 survey, with continued improvement in hospital outcomes.
