%X Resumen: El t¨¦rmino s¨ªndrome X o angina microvascular se emplea habitualmente para definir a un grupo de pacientes que presentan dolor tor¨¢cico caracter¨ªstico, depresi¨®n del segmento ST durante el esfuerzo y arterias coronarias angiogr¨¢ficamente normales. Muchos datos apuntan a un posible origen isqu¨¦mico de los s¨ªntomas. Es m¨¢s frecuente en mujeres y en casi el 50 % de ellas, el dolor anginoso se atribuye espec¨ªficamente a cambios en la microvasculatura coronaria. Debido a que el pron¨®stico no es tan benigno como se cre¨ªa hace a os, en pacientes con angina y coronarias epic¨¢rdicas normales, se impone una evaluaci¨®n cl¨ªnica (incluyendo un cuidadoso an¨¢lisis de los factores de riesgo) e imagenol¨®gica, con el prop¨®sito de detectar isquemia funcionalmente significativa. La enfermedad coronaria microvascular es, por tanto, una enfermedad que requiere atenci¨®n por parte del m¨¦dico de asistencia. En este art¨ªculo se presenta una paciente con este diagn¨®stico, y se muestran las im¨¢genes electrocardiogr¨¢ficas, ecocardiogr¨¢fica, ergom¨¦tricas y angiogr¨¢ficas. / Abstract: The term cardiac syndrome X or microvascular angina is commonly used to describe a group of patients who show a typical chest pain, ST segment depression during exercise and angiographically normal coronary arteries. Many data suggest the symptoms may have an ischemic origin. It is more common in women, and, in almost 50% of them, anginal pain is specifically attributed to changes in the coronary microvasculature. The prognosis is not as benign as it was believed for years; therefore, in patients with angina and a normal epicardial coronary, a clinical and imaging assessment is necessary (including a careful analysis of risk factors) in order to detect a functionally significant ischemia. Therefore, coronary microvascular disease is a condition that requires attention by the attending physician. A patient with this diagnosis is reported in this article, and electrocardiographic, echocardiographic, ergometric and angiographic images are shown.
