RESUMEN
Se examinó la asociación entre el estrés psicológico (EP) y la prehiperten sión (PH) en adolescentes. La muestra estuvo conformada por 690 adolescentes: 260 varones y 430 hembras, con una media de edad de 15 años, (DE=1,5), a quienes se les determinó su presión arterial (PA) en la escuela, en posición sentada y usando el método oscilométrico (Dinamap). Todos, sin excepción, completaron una encuesta sobre eventos de vida y evaluación de ajuste social, ambas escalas asociadas con estresores vitales en adolescentes. Los partici pantes se clasificaron de acuerdo a los niveles de PA en prehipertensos (PH) y normotensos (N). La presencia de EP se evaluó como graves acontecimientos estresantes en su vida. Se utilizó la prueba de Chi cuadrado para estudiar la asociación entre EP y la presencia de PH. Los resultados arrojaron la presencia de EP en 70 varones (26,9%) y 155 hembras (36,0%), mientras que la prevalencia de prehipertensión fue de 9,2% (n=24) en varones y 3,5% (n=15) en hembras. Al aplicar la prueba estadística de Chi cuadrado en todos los adolescentes no se demostró asociación significativas entre EP y la condición de prehipertensión (PH con EP = 15 vs. N con EP = 24 (P = 0,42)). Sin embargo, al clasificar los sujetos por género, se encontró una asociación significativa entre EP y PH en las hembras (PH con EP = 9 vs. N con EP = 6, (P = 0,04)). El resultado anterior sugiere que, a edades tempranas, las mujeres pueden ser más vulnerables que los hombres al EP como un factor determinante a la condición de PH.
The article examines the association between psychological stress (PS) and prehypertension (PH) in 690 adolescents, 260 males and 430 females, whose average age was 15.2 years (SD = 1.5). Their blood pressure (BP) was measured on separate days at school, by the oscillometric method (Dinamap) in a seating position. All of them completed a survey assessing life events and social readjustment (both scales associated with life stressors in adolescen ce). Participants were classified according to BP levels in prehypertensive (PH) and normoten sive (N). The presence of PS was evaluated as severe stressful life events. The Chi-square test was used to study the association between PS and the presence of PH. The results showed the presence of PH in 9.2% (n = 24) in males and 3.5% (n = 15) in females, while the presence of PS ocurred in 70 males (26.9%) and 155 females (36.0%).When applied to the whole data, the Chi-square statistical test showed no association between PS and the condition of prehyperten sion (PH with PS = 15 vs. N with PS = 24, (P= 0.42)). However, when subjects were classified by gender, there was a significant association between PS and PH in female adolescents (PH with PS = 9 vs N with PS = 6 (P = 0.04)). This result suggests that, at early ages, female adolescents may be more vulnerable than males to PS as a determining factor to the condition of PH.

The connection between fever and sudden death due to ventricular tachycardia has been usually reported in Brugada Syndrome. However the thermosensitive effects caused by fever have been recently described as a possible cause of sudden death in congenital long QT type II syndrome and in idiopathic ventricular fibrillation syndrome. We present a case where fever unmasked a congenital long QT type II syndrome.
La asociación entre fiebre y muerte súbita debido a taquicardias ventriculares clásicamente se ha reportado en el Síndrome de Brugada. Sin embargo, recientemente se ha descrito que los efectos termosensibles de la fiebre pueden ocasionar muerte súbita en el síndrome de QT Largo congénito tipo II y en el síndrome de fibrilación ventricular idiopática. Presentamos un caso clínico donde la fiebre desenmascaró un síndrome de QT largo congénito tipo II.
