En el presente trabajo se intenta establecer si alguno de los componentes dei clásico Patrón de Conducta Tipo A (PCTA) puede seguir siendo utilizado con alguna credibilidad a la hora de localizar el eventual riesgo de trastomo coronario. La muestra estuvo conformada por mujeres que habían sufrido un infarto de miocardio. Utilizando el Factor S del Jenkins Activity Survey, se formaron dos grupos de mujeres: con alta y baja puntuación. A todas se les registro la tasa cardíaca durante una prueba de esfuerzo, midiendo, además, la incidência sintomatológica diversa a lo largo de tres meses tras la alta en el Hospital. Nuestros resultados nos permiten sugerir que el Factor S del JAS, que mide prisa e impaciência, parece un critério apropiado para investigar el riesgo de enfermedad coronaria. Así, Ias mujeres que puntuaron alto en este factor mostraban perfiles psicofisiológicos específicos cartacterizados por la lenta recuperación tras la tarea o fase de esfuerzo. Además, estas mujeres experimentaron una mayor incidência de sintomas psicológicos. Se discute que Ias mujeres Tipo A parecen encontrarse más sensibilizadas en la percepción de Ias situaciones de estrés, y sus conseqüências.<br>The present work tries to settle down if some of the components of Type A Behavior Pattern (TABP) can be used with some credibility to locate an eventual risk of coronary dysfunction. The sample was composed by women that had suffered a myocardial infarct. Using the S Factor of the Jenkins Activity Survey, two groups of women were formed: with high and low score. To all these women the heart rate during a test of effort was measured, and also, the incidence of diverse symptoms along three months after the hospital depart. Our results allow us to suggest that the Factor S of the JAS, which measures speed and impatience, seems an appropriate approach to investigate the risk of coronary illness. So, the women that punctuated high in this factor showed specific psychophysiological profiles, in which a slow recovery after the effort phase was observed. Also, these women experienced a higher incidence of psychological symptoms. This fact makes us suggest that Type A women seem to be more sensitive in the perception of the stress situations.
