Abstract
La disección coronaria espontánea (DCE) es una causa frecuente de infarto agudo de miocardio, sobre todo en mujeres de mediana edad y es cada vez más reconocida por sus implicancias fisiopatológicas, diagnósticas y terapéuticas particulares. La fisiopatología subyacente a la disección coronaria espontánea involucra diferentes aspectos de la disfunción vascular coronaria y sigue siendo en gran medida desconocida. Hemos identificado 3 áreas de investigación que involucran a diferentes mecanismos de disfunción vascular coronaria. En primer lugar, sabemos que la disfunción endotelial es un trastorno vascular presente en diferentes patologías coronarias y su contribución en la disección coronaria espontánea es aún desconocida. En segundo lugar, las hipótesis que abarcan el papel fisiopatológico potencial de las hormonas sexuales en la disección coronaria espontánea están respaldadas por la clara preponderancia femenina de la enfermedad y su relación con el embarazo, sin embargo, se desconoce el papel de la terapia hormonal exógena en el momento diagnóstico de la DCE. En tercer lugar, se desconoce el pronóstico clínico de los diferentes tipos angiográficos de DCE, existe cierta evidencia de una tasa de eventos adversos elevada en los casos de hematoma intramural contenido en el seguimiento a corto plazo, pero se desconoce su comportamiento clínico en el largo plazo. Los 3 mecanismos de disfunción vascular de la DCE mencionados serán estudiados en la presente tesis doctoral...
Spontaneous coronary artery dissection (SCAD) is a common cause of acute myocardial infarction, especially in middle-aged women and is increasingly recognized for its pathophysiological, diagnostic, and therapeutic implications. Pathophysiology underlying spontaneous coronary dissection involves different aspects of the coronary vascular dysfunction and remains largely unknown.We have identified 3 areas of research that involve different mechanisms of coronary vascular dysfunction. First, we know that endothelial dysfunction is a vascular disorderpresent in different coronary pathologies and its contribution in spontaneous coronary dissection is still unclear. Second, hypotheses encompassing the role of sex hormones in SCAD are supported by the clear female preponderance of the disease and its relationship with pregnancy, however, the role of exogenous hormone therapy in the time of diagnosis of SCAD is not clear. Third, the clinical prognosis of the different angiographic subtypes of SCAD is not well defined, there is some evidence of a higher rate of adverse events in cases of contained intramural hematoma at short-term follow-up, however its behavior is unknown in the long-term follow-up. The 3 mechanisms of vascular dysfunction of SCAD mentioned will be studied in the present doctoral thesis...
