Objectives. To evaluate the rate of use of antiplatelet pretreatment in patients with non-ST elevated acute coronary syndrome (NSTEACS) and its association with adverse events in two Argentine registries. Materials and methods. We retrospectively analyzed two Argentine acute coronary syndrome (ACS) registries from 2017 and 2022. We explored the incidence of pretreatment and the drug used. We evaluated the relationship between this strategy and a composite clinical outcome of in-hospital events: death + myocardial infarction + stent thrombosis + post-MI angina + transient ischemic event/cerebrovascular event, and with bleeding events (BARC 2 or higher). Subsequently, we performed a multivariate analysis by logistic regression with other clinical variables. Results. A total of 1297 patients were included; 75.6% were men, 25.6% diabetics, 27.1% smokers, 70.3% hypertensive, and 23.1% had a p...

Objetivo. Identificar predictores independientes de cirugía de revascularización miocárdica (CRM) en pacientes con síndrome coronario agudo sin elevación del segmento ST (SCASEST) del mundo real. Materiales y métodos. Se realizó un análisis preespecificado de forma individual de pacientes con SCASEST, a partir de dos registros argentinos prospectivos entre 2017 y 2022. Se analizó la diferencia en las características basales entre los pacientes que requirieron CRM y los que no requirieron esta intervención. Luego, se realizó un análisis de regresión logística para determinar predictores independientes en los pacientes que recibieron CRM como método de revascularización. Resultados. Se incluyeron 1848 pacientes con una mediana de edad de 54,8 (rango intercuartílico [RIC]): 53,7-56) años y una fracción de eyección de 42,1% (RIC: 41,2-43,1). Un total de 233 pacientes...
