ABSTRACT
Resumen La amiloidosis sistémica constituye una enfermedad poco frecuente, donde la infiltración cardíaca es la principal causa de morbimortalidad, sin importar la causa subyacente del depósito amiloide. Se reporta el caso de una paciente femenina de 48 años con síndrome nefrótico, insuficiencia cardíaca e inmunocompromiso, estableciéndose el diagnóstico de amiloidosis primaria con infiltración cardíaca secundaria a mieloma múltiple. Se discute brevemente la enfermedad, la importancia del juicio clínico apoyado en medios diagnósticos y los retos terapéuticos actuales.
Abstract Systemic amyloidosis constitutes a non common disease in which cardiac involvement is the leading cause of morbidity and mortality, regardless of the underlying pathogenesis of amyloid production. We present the case of a 48 years old female with nephrotic syndrome, heart failure and immunocompromise in which Primary Amyloidosis with cardiac involvement secondary to Multiple Myeloma is established as diagnosis. The disease is briefly discussed, as well as the value of clinical judgment supported on diagnostic means and the therapeutic challenges now days.
