RESUMO

Objective: The objective of the study is to identify clinical and angiographic characteristics of patients with ST-segment elevation myocardial infarction (STEMI) but without clinical manifestations of COVID-19 infection during the pandemic, compared with patients 1 year before the pandemic. Methods: Observational study that included 138 consecutive patients hospitalized with STEMI who underwent primary percutaneous coronary intervention (PCI) without COVID-19 infection during the 2020 pandemic. A group of 175 STEMI patients treated with PCI in the year before the pandemic served as the control group. Results: During the periods analyzed, compared with the control group, patients admitted during the pandemic without clinical manifestations of COVID-19 did not have significant differences in demographic characteristics, comorbidities, or delayed time and location of the acute myocardial infarction. Furthermore, there were no differences between the two groups concerning levels of CK-MB and NT-proBNP, or in inflammation markers and left ventricular ejection fraction. In patients without COVID-19 during the pandemic compared with control, we found a higher intracoronary thrombus burden (thrombus grade 5; 78.3% vs. 62.9%, respectively. p = 0.002). Accordingly, the use of glycoprotein IIB/IIIa inhibitors (37.7% vs. 26.3%, p = 0.03) was higher in these patients. Conclusions: This study demonstrates an increased thrombus burden in STEMI patients without clinical manifestation of COVID-19 during the pandemic compared with the same time period in the previous year.


Objetivo: Identificar las características clínicas y angiográficas de los pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMCEST) sin manifestaciones clínicas de COVID-19 durante la pandemia y compararlos con los pacientes en el año previo. Métodos: Estudio observacional que incluyó 138 pacientes consecutivos que fueron hospitalizados por IAMCEST y que fueron tratados con angioplastía primaria (ACTP) sin manifestaciones clínicas de COVID-19 durante la pandemia de 2020. Se seleccionó a un grupo control de 175 pacientes con IAMCEST tratados con ACTP en el año previo a la pandemia. Resultados: Los pacientes atendidos durante la pandemia no tuvieron diferencias significativas en cuanto a las características clínicas, demográficas, comorbilidades, tiempo de retraso y localización del infarto. Además, no hubo diferencias entre ambos grupos en los niveles de CK-MB, NT-proBNP, marcadores de inflamación ni en la fracción de eyección del ventrículo izquierdo. En los pacientes sin COVID-19 tratados durante la pandemia encontramos mayor carga trombótica intracoronaria (trombo grado 5; 78.3% vs. 62.9%, respectivamente. p = 0.002). De igual manera, el uso de inhibidores de la glucoproteina IIB/IIIa (37.7% vs. 26.3%, p = 0.03) fue mayor. Conclusiones: Este studio demostró un aumento en la carga trombótica en los pacientes con IAMCEST sin manifestaciones clínicas de COVID-19 durante la pandemia al compararlos con los pacientes tratados por la misma patología en el año previo.
