ABSTRACT

Estudos recentes têm sugerido uma associação entre hipertensão arterial pulmonar (HAP) e tireoidopatias (hipotireoidismo e hipertireoidismo). Esta associação tem um bom prognóstico, porque o aumento na pressão da artéria pulmonar geralmente é leve e reversível com o tratamento da tireoidopatia. O mecanismo exato envolvido na patogênese desta associação não está estabelecido, e a influência direta dos hormônios da tireoide e a autoimunidade são consideradas como hipóteses. Devido à alta prevalência de doenças da tireoide em pacientes com HAP, testes de função tireoidiana devem ser considerados na investigação de todo paciente com HAP. Neste artigo de revisão, descrevemos a prevalência de HAP em pacientes com doenças da tireoide e a prevalência de tireoidopatias em pacientes com HAP, assim como destacamos os principais efeitos das doenças da tireoide no sistema respiratório. A seguir, relatamos os efeitos do tratamento destas patologias.


Recent studies have suggested an association between pulmonary arterial hypertension (PAH) and thyroid diseases (hypothyroidism and hyperthyroidism). This combination has a good prognosis, because the increase in the pulmonary artery pressure is usually slight and reverses after the treatment of the thyroid disease. Although the exact mechanism involved in the pathogenesis of this combination has not yet been established, it has been hypothesized that thyroid hormones and autoimmunity have a direct influence. Due to the high prevalence of thyroid disease in patients with PAH, thyroid function tests should be considered in the investigation of every patient with PAH. In this review, we describe the prevalence of PAH in patients with thyroid diseases and the prevalence of thyroid disease in patients with PAH, as well as addressing the principal effects that thyroid diseases have on the respiratory system. In addition, we report the treatment effects in patients with these diseases.
