[Reperfusion in ST elevation myocardial infarction. From the guidelines to practice].
Annales de Cardiologie et D'angéiologie 2014 November
BACKGROUND: International guidelines have recommendations for selecting the type of reperfusion (fibrinolysis or angioplasty) in the setting of ST-segment elevation myocardial infarction (STEMI), and suggest that emergency-care networks adapt these recommendations according to the local environment.
AIM: To assess the proportions of STEMI patients treated with fibrinolysis or angioplasty in accordance with regional guidelines.
METHOD: Observational study based on a permanent registry of patients with STEMI of <12h duration in an emergency network in the French North Alps (Isère, Savoie, Haute-Savoie) from January 2009 to December 2012.
RESULTS: The registry included 2620 patients. Reperfusion was given in 2425/2620 (93%) of patients. Reperfusion type was in accordance with recommendations in 1567/2620 (60%) patients. Guideline-recommended fibrinolysis and angioplasty were performed in 47% (656/1385) and 79% (911/1149) respectively, of patients. In multivariable analysis, variables independently associated with guideline-recommended reperfusion were: an age < 65 years (OR 1.60; 95%CI 1.33-1.90), being managed in Haute-Savoie versus Isère or Savoie (OR 1.38; 95%CI 1.12-1.71), an arterial tension < 100mmHg (OR 1.73; 95%CI 1.27-2.35), a cardiogenic shock (OR 0.50; 95%CI 0.30-0.84), a pacemaker or left bundle branch block (OR 0.49; 95%CI 0.28-0.88), and an initial management outside the network (followed by treatment in an interventional centre in the network) (OR 0.62; 95%CI 0.40-0.94). Patients initially treated by mobile intensive care units were more often reperfused in accordance with recommendations when admitted < 3 (versus ≥ 3) h following symptom onset (adjusted OR 2.05; 95% CI 1.61-2.59), while those initially treated by in-hospital emergency units were less often reperfused in accordance with recommendation when treated < 3h following symptom onset (adjusted OR 0.67; 95% CI 0.46-0.97). In-hospital major adverse cardiac events (9.1% vs. 8.5%) and in-hospital mortality (6.4% vs. 5.1%) were not significantly different between patients reperfused in accordance with (versus not) recommendations.
CONCLUSIONS: Forty percent of patients with STEMI were not reperfused with fibrinolysis or angioplasty in accordance with regional guidelines. Characterization of this population should allow us to improve guideline adherence.
