          Abstract

          RESUMEN Introducción: El infarto de miocardio sin obstrucciones coronarias significativas (MINOCA) es una conocida entidad que se ha redefinido recientemente al excluir la injuria miocárdica no isquémica. ReSCAR fue un registro prospectivo, multicéntrico de pacientes hospitalizados por síndrome coronario agudo (SCA) desde enero hasta agosto de 2022. Objetivo: Un objetivo principal del registro fue definir la prevalencia de pacientes con MINOCA, sus características basales clínicas y paraclínicas y evolución intrahospitalaria. Los resultados del análisis respectivo son la base de esta publicación. Material y métodos: Registro nacional prospectivo y multicéntrico de SCA. Diagnóstico de MINOCA de acuerdo con la Cuarta Definición Universal de Infarto de Miocardio. Análisis de las características basales, evolución y diferencias significativas respecto de los pacientes con coronariopatía obstructiva. Los centros participantes debían contar con determinación de troponina de alta sensibilidad y la posibilidad de realizar cinecoronariografía. Resultados: Se incluyeron 984 pacientes de 15 centros. Ochenta y cinco pacientes (8,6 %) tuvieron diagnóstico final de MINOCA al alta. Cuarenta y cuatro pacientes (51,8 %) eran mujeres, la mediana de edad fue de 65 años (53-63), 55 (64,7 %) pacientes eran hipertensos, 44 (51,8 %) dislipidémicos, 9 (10,6 %) diabéticos y 23 (27,1 %) fumadores. La mediana de troponina al ingreso (expresada como múltiplo del percentilo 99) fue de 2,42 (0,85-10,21) y el 71,8 % se presentó con un ECG sin cambios isquémicos. La angiografía coronaria fue normal en el 72,9 % de los pacientes y con lesiones menores de 50 % en el resto. Se realizó resonancia cardíaca a 16 pacientes. La mediana del score GRACE fue de 115 puntos (98-139), lo cual perfila un riesgo intermedio; con una tasa de eventos combinados de accidente cerebrovascular/infarto o muerte de 1,2 %, sin haberse registrado sangrados BARC 2 o más. La prescripción al alta de aspirina fue del 72,9 %, clopidogrel 27,1 %, estatinas 88,2 %, beta bloqueantes 67,1 % y antagonistas cálcicos 22,4 %. Conclusión: En este registro, los pacientes con MINOCA representan una proporción significativa de aquellos con SCA. La tasa de complicaciones intrahospitalarias, incluida la mortalidad, fue baja. Impresiona existir una fuerte oportunidad para profundizar los estudios para confirmar este diagnóstico, sus mecanismos fisiopatológicos y su tratamiento.

          ABSTRACT Background: Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a well-known condition that has been recently redefined after excluding non-ischemic myocardial injury. ReSCAR was a prospective, multicenter registry of patients hospitalized for acute coronary syndrome (ACS) from January to August 2022. Objective: One of the main objectives of the registry was to define the prevalence of patients with MINOCA, their baseline clinical and paraclinical characteristics, and in-hospital outcome. This publication focuses on the results of the respective analysis. Methods: We conducted a nationwide, multicenter, prospective study of patients with ACS. The diagnosis of MINOCA was made following the Fourth Universal Definition of Myocardial Infarction. The baseline characteristics of the patients wereanalyzed, as well as their outcome and significant differences with patients with obstructive coronary artery disease. The participating centers should have the availability to measure high-sensitivity cardiac troponin and perform coronary angiography. Results: A total of 984 patients from 15 centers were included. Eighty-five patients (8.6%) had a final diagnosis of MINOCA at discharge. Median age was 65 years (53-63), 48 (51.8%) were women, 55 (64.7%) had hypertension, 44 (51.8%) had dyslipidemia, 9 (10.6%) were diabetics and 23 (27.1%) were smokers. Median high-sensitivity cardiac troponins on admission (expressed as multiples of the 99th percentile) were 2.42 times higher (0.85-10.21) and the ECG had no ischemic changes in 71.8% of the patients. Coronary angiography was normal in 72.9% of the patients and the rest of the cases had coronary artery stenoses < 50%. Sixteen patients underwent cardiac magnetic resonance imaging. The median GRACE score was 115 (98-139), which corresponds to intermediate risk. The event rate for the composite outcome of stroke/myocardial infarction or death was1.2%, and there were no bleeding events BARC ≥type 2. The discharge prescription rate was 72.9% for aspirin, 27.1% for clopidogrel, 88.2% for statins, 67.1% for beta-blockers, and 22.4% for calcium channel blockers. In this registry, patients with MINOCA represent a significant proportion of those with ACS. Conclusion: The rate of in-hospital complications, including mortality, was low. There seems to be a strong opportunity for further investigations to confirm the diagnosis, pathophysiological mechanisms, and treatment of MINOCA.

          The REDCap consortium: Building an international community of software platform partners

          The Research Electronic Data Capture (REDCap) data management platform was developed in 2004 to address an institutional need at Vanderbilt University, then shared with a limited number of adopting sites beginning in 2006. Given bi-directional benefit in early sharing experiments, we created a broader consortium sharing and support model for any academic, non-profit, or government partner wishing to adopt the software. Our sharing framework and consortium-based support model have evolved over time along with the size of the consortium (currently more than 3200 REDCap partners across 128 countries). While the "REDCap Consortium" model represents only one example of how to build and disseminate a software platform, lessons learned from our approach may assist other research institutions seeking to build and disseminate innovative technologies.

            Systematic review of patients presenting with suspected myocardial infarction and nonobstructive coronary arteries.

            Myocardial infarction with nonobstructive coronary arteries (MINOCA) is a puzzling clinical entity with no previous evaluation of the literature. This systematic review aims to (1) quantify the prevalence, risk factors, and 12-month prognosis in patients with MINOCA, and (2) evaluate potential pathophysiological mechanisms underlying this disorder.

              Contemporary Diagnosis and Management of Patients With Myocardial Infarction in the Absence of Obstructive Coronary Artery Disease: A Scientific Statement From the American Heart Association

              Myocardial infarction in the absence of obstructive coronary artery disease is found in ≈5% to 6% of all patients with acute infarction who are referred for coronary angiography. There are a variety of causes that can result in this clinical condition. As such, it is important that patients are appropriately diagnosed and an evaluation to uncover the correct cause is performed so that, when possible, specific therapies to treat the underlying cause can be prescribed. This statement provides a formal and updated definition for the broadly labelled term MINOCA (incorporating the definition of acute myocardial infarction from the newly released "Fourth Universal Definition of Myocardial Infarction") and provides a clinically useful framework and algorithms for the diagnostic evaluation and management of patients with myocardial infarction in the absence of obstructive coronary artery disease.
