RESUMO

Resumen OBJETIVO: Comparar la capacidad predictiva de mioglobina, creatincinasa total y hemoglobina en orina de lesión renal aguda en pacientes con traumatismo. MATERIAL Y MÉTODO: Estudio transversal, analítico, comparativo, observacional, en el que se identificaron todos los pacientes mayores de 18 años con diagnóstico de traumatismo o politraumatismo, provenientes del servicio de urgencias, de agosto de 2017 a enero de 2018 en el Hospital General Xoco de la Secretaría de Salud de la Ciudad de México, se midieron: mioglobina, creatincinasa total, concentraciones de creatinina y hemoglobina en orina a su ingreso. RESULTADOS: Se incluyeron 24 pacientes de 20 a 79 años de edad, con predominio del género masculino. Al comparar las áreas bajo la curva de las pruebas se determinó que no hubo significación estadística (p = 0.266) para la creatincinasa de ingreso porque mostró un área bajo la curva de 0.636, el intervalo de confianza al 95% se encontró por debajo de 0.500. Asimismo, la mioglobina de ingreso se observó en un área bajo la curva de 0.657 (p = 0.198; IC 95% 0.423-0.891). CONCLUSIONES: Las concentraciones de creatincinasa total y mioglobina no demostraron ser predictores adecuados de lesión renal al no haber diferencia significativa; sin embargo, se encontró que las concentraciones de creatinina al ingreso tienen mayor capacidad predictiva de lesión renal aguda en pacientes con traumatismo e hiperCKemia.


Abstract OBJECTIVE: To compare the predictive capacity of myoglobin, total creatine kinase and urine hemoglobin for acute renal injury in patients with trauma. MATERIAL AND METHOD: A cross-sectional, analytical, comparative, observational study was made with all adults over 18 years of age with a diagnosis of trauma or polytraumatism from August 2017 to January 2018 in the General Hospital of Xoco, Mexico City. Myoglobin, total creatine kinase, creatinine and hemoglobin levels were measured in urine at their admission. RESULTS: There were studied 24 patients from 20 to 79 years old, with a predominance of the male gender. When comparing the areas under the test curve it was determined that there was no statistical significance (p = 0.266) for the creatine kinase at the patient's admission, as it showed an area under the curve of 0.636, the 95% confidence interval was below 0.500. Likewise, the myoglobin at the patient's admission was observed under the curve area of 0.657 (p = 0.198; IC 95% 0.423-0.891). CONCLUSIONS: Levels of total creatine kinase and myoglobin did not prove to be adequate predictors of kidney injury because there was no significant difference. However, creatinine levels at admission have greater predictive capacity of acute renal injury in patients with trauma and hyperCKemia.

RESUMO

Resumen OBJETIVO: Establecer si la exposición al enojo una hora previa es factor de riesgo de infarto agudo de miocardio. MATERIAL Y MÉTODO: Estudio transversal, retrospectivo, analítico, mediante un diseño de caso cruzado. Se aplicó una encuesta y se revisó el expediente de pacientes para conocer sus niveles de enojo basales o habituales y los niveles de enojo 24, 12, 8, 4, 2 y una horas previo a padecer el síndrome coronario agudo. RESULTADOS: Se incluyeron 26 pacientes. El estrés emocional, en este estudio medido por el enojo, mostró no estar asociado con el síndrome coronario agudo de tipo infarto agudo de miocardio con y sin elevación del segmento ST. CONCLUSIONES: El enojo una hora previa funge como factor protector de síndrome coronario agudo de tipo infarto de miocardio. Es probable que nuestro estudio no haya mostrado diferencia debido a un sesgo de memoria o a que el tamaño de la muestra haya sido insuficiente para demostrar tal asociación.


Abstract OBJECTIVE: To establish if the exposure to anger one hour before is a risk factor of acute myocadial infarction. MATERIAL AND METHOD: A cross-sectional, retrospective, analytical, by a design of crossed case. A survey was conducted, and the file was reviewed of patients to know their basal or habitual levels of anger and the levels of anger 24, 12, 8, 4, 2, one hours prior to presenting the acute coronary syndrome, to assess if there is a relationship between these and between associated factors (dyslipidemia, smoking, uncontrolled glycemia). RESULTS: There were included 26 patients. Emotional stress, in this study measured by anger, showed not to be associated with acute coronary syndrome of acute myocardial infarction type with and without ST-segment elevation. CONCLUSIONS: Anger one hour prior acts as a protective factor of acute myocardial infarction coronary syndrome. It is likely that our study showed no difference due to a memory bias or that the sample size was insufficient to demonstrate such an association.
