Resumen
El hipertiroidismo subclínico (HSC) puede definirse como aquella condición en la que existen bajos niveles de TSH en un paciente asintomático con niveles normales de T4 libre (T4L) y T3. La secreción de TSH puede incluso encontrarse suprimida en presencia de niveles normales de T3 y T4L. La introducción, a mediados de la década de los \'80, de las determinaciones más sensibles para medir los niveles de la TSH y los métodos de tercera generación han permitido detectar aproximadamente 0.01 microunidades/mL (0.01 mU/L). El HSC puede ser una entidad variada según se trate de enfermedad de Graves o de bocio multinodular evolucionado. Los pacientes con estas patologías no presentan signos clínicos de hipertiroidismo clínico evidente. La historia clínica detallada y la evolución llevan a evaluar el HSC por los efectos que puede producir sobre corazón y hueso. Una opción razonable de tratamiento para la mayoría de los pacientes es la utilización de bajas dosis de antitiroideos durante 12 meses, en un esfuerzo para inducir la remisión.

Abstract
Subclinical thyrotoxicosis may be defined as a low serum thyrotropin (TSH) concentration in an asymptomatic patient with normal serum free thyroxine (T4L) and triiodothyronine (T3). The introduction in the mid-1980s of sensitive assays for TSH and a third-generation assay capable of detecting approximately 0.01 μU per mL (0.01 mU per L). Subclinical hyperthyroidism may be a distinct clinical entity, related only in part to Graves´ disease or multinodular goiter. Persons with subclinical hyperthyroidism usually do not present with specific signs or symptoms associated with over hyperthyroidism. A detailed clinical story should be obtained, a physical and evolution conducted as part of an assessment of patients for subclinical hyperthyroidism and to ealuate the possible deleterious effects of excess thyroid hormone on end organs (heart, bone). A reasonable option for many patients is a therapheutic trial of low dose antithyroid agents for approximately six to 12 months in an effort to induce a remission.
