Representative data on the current management of patients with acute coronary syndromes (ACS) are of high interest. The EPICOR registry aimed to prospectively collect such real-life data with particular focus on antithrombotic drug utilization and outcomes.
As part of the international prospective EPICOR registry, 29 hospitals in Germany documented 296 patients with ST-elevation myocardial infarction (STEMI)-ACS and 333 with unstable angina or non-STEMI (NSTEMI)-ACS surviving the hospital phase. The statistical analysis was performed in a descriptive manner. The ClinicalTrials.gov identifier is NCT01171404.
The mean age of patients was 62 ± 13 years, and 77.4 % were men. Treatment with antithrombotic agents was initiated in the prehospital phase in 50.7 % of STEMI and 33.3 % of NSTEMI patients. During the hospital stay (median 7.0 days), cardiac catheterization was performed in 97.6 %, percutaneous coronary intervention in 85.6 %, thrombolysis in 4.6 %, and coronary bypass surgery in 2.7 % patients. The use of acetylic salicylic acid (ASA) was reported in 95.6 % vs. 96.1 %, clopidogrel in 60.8 % vs. 73.0 %, prasugrel in 45.6 % vs. 22.5 %, any GP IIb/IIIa inhibitor in 52.4 % vs. 18.9 % [any dual combination of ASA+(clopidogrel/prasugrel)in 94.0 vs. 91.0 %], statins in 94.6 % vs. 92.2 %, beta blockers in 96.3 % vs. 94.6 %, and ACE-I/ARB in 91.6 % vs. 87.7 % of STEMI vs. NSTEMI patients, respectively. Combined use of the five drug classes recommended in the guidelines-ASA, P2Y12 antagonists, statin, beta blocker, and ACE-I/ARB-was reported in 81.1 % vs. 69.4 % of STEMI vs. NSTEMI patients, respectively.
In Germany a high proportion of patients with ACS are treated according to current guidelines, receiving primary revascularization as well as antithrombotic drugs and other agents for prevention of secondary events; associated bleeding complications were less frequent as compared with published registries.
