RIVERO, Mirza et al. Acute Coronary Syndromes in High Complexity Centers of Argentina. The ReSCAR Registry. Rev. argent. cardiol. [online]. 2023, vol.91, n.3, pp.205-211. ISSN 1850-3748.


: We conducted a multicenter registry to analyze the diagnostic and therapeutic approach to all types of acute coronary syndromes; this registry is the first to provide detailed information on conditions without significant epicardial coronary artery disease. Knowing the reality of current medical practice is important to find opportunities for improvement.


: Patients hospitalized for acute coronary syndrome between January and August 2022 in 15 centers of Argentina, with high-sensitivity cardiac troponin, coronary care unit, and catheterization laboratory available 24 hours, were prospectively recorded.


: A total of 984 consecutive patients were included, 22.2% with unstable angina, 39.1% with non-ST-segment elevation myocardial infarction (NSTEMI) and 24.1% with ST-segment elevation myocardial infarction (STEMI). Additionally, 4.1% presented as type 2 AMI, 1.2% as myocarditis, 0.7% as Takotsubo syndrome and 8.6% as myocardial infarction with non-obstructive coronary arteries (MINOCA). Median age was 66 years [interquartile range (IQR) 56.5-74] and 75.3% were men. An early invasive management was used in 84% of patients without ST segment elevation, and 76.5% of them had significant coronary artery disease. During hospitalization, 2.84% of the patients presented reinfarction, 2.43% recurrent angina, 2% postinfarction angina and 0.5% stent thrombosis. Bleeding events occurred in 4.4% of the patients, and overall in-hospital mortality was 3.76%.


: The registry has a good representation of the spectrum of patients with initial suspicion of “acute coronary syndrome”, managed in centers with an invasive initial strategy and with low rate of in-hospital complications and acceptable overall mortality.
