RESUMO
Abstract Objective: Women with ST-segment elevation myocardial infarction (STEMI) have worst outcomes than men. The objective of the study was to determine gender differences in mortality in patients with STEMI. Methods: Cohort study including patients with STEMI. We recorded demographic and clinical data, laboratory tests, and in-hospital mortality in patients who underwent primary angioplasty and pharmacoinvasive strategy. Kaplan-Meier analysis was used to assess mortality differences between both genders. Results: A total of 340 patients were analyzed, 296 males and 44 females. Mean age of the female group was 64.3 ± 12.3 years. About 98% of females were among Killip-Kimball Class I-II. They had higher risk scores compared to man, longer ischemic time and first medical contact with a difference in comparison to man of 47 and 60 min, respectively. Mortality was 9.1% (4) in the female group. Conclusions: Although the proportion of women had higher mortality than man, we did not found any difference with statistical significance probably due to the lack of representation. We need more awareness in the female population about STEMI, since longer first medical contact time and longer total ischemic time might be one possible explanation of a higher mortality.
Resumen Objetivo: Las mujeres con infarto agudo al miocardio con elevación del segmento ST (SICA CEST) tienen peor pronóstico que los hombres. El objetivo fue determinar las diferencias de mortalidad en género en pacientes con SICA CEST. Metodos: Estudio de cohorte de pacientes con SICA CEST. Se recolectaron datos demográficos, clínicos, de laboratorio y mortalidad intrahospitalaria. Se realizó un análisis de Kaplan-Meier para valorar la mortalidad y determinar diferencias de género. Resultados: Se analizaron 340 pacientes, 296 hombres y 44 mujeres. Se observó que las mujeres tuvieron mayores puntajes en los scores de riesgo, mayor tiempo de primer contacto y tiempo total de isquemia encontrando una diferencia con el grupo de hombres de 47 y 60 minutos respectivamente. La mortalidad intrahospitalaria fue de 9.1% (4) sin diferencia estadísticamente significativa en comparación con los hombres. Conclusiones: Aunque la proporción de mujeres tuvo mayor mortalidad no se encontró diferencia estadísticamente significativa en comparación con los hombres probablemente por el tamaño de la muestra debido a baja representación del grupo femenino. Se necesita mayor conciencia en relación al infarto en el grupo de mujeres, ya que mayor tiempo de primer contacto y mayor tiempo total de isquemia pueden ser una posible explicación de una mayor mortalidad.
