Abstract

The epidemiology of pulmonary hypertension (PH), especially pulmonary arterial hypertension (PAH), has not been evaluated in our country, therefore there is no reference parameter to establishing the representativeness of this information in the national order. This registry represents the first collaborative effort to provide a knowledge base of this disease, including 5 scientific societies that represent different specialties (pediatrics, rheumatology, pulmonology and cardiology) with data from 23 Argentine provinces. These efforts involved five societies of various adult (cardiology, rheumatology, and pulmonology) and pediatric (cardiology) specialties. Subjects were grouped (1-5) in accord with the 2013 Nice classification. A total of 627 patients (mean age, 50.8 ± 18 years; women, 69.2%) were recruited. Incident cases accounted for 53%. Functional class III-IV accounted for 69% at time of diagnosis and 33.4% at time of inclusion. Distributions in groups 1-5 were 63.6%, 15.9%, 8.3%, 9.7%, and 2.4%, respectively. Treatment consisted of diuretics (51.2%), mineralocorticoid receptor antagonists (44.7%), digoxin (16.6%), anticoagulants (39.2%), renin-angiotensin antagonists (15.5%), beta blockers (15.6%), and calcium channel blockers (8%). Rates of specific therapies usage in PAH vs. non-PAH group were 80.5% vs. 40.8% (phosphodiesterase-5 inhibitors: 71% vs. 38.6%; endothelin receptor antagonists: 54.4% vs. 14.5%; prostanoids: 14.3 vs. 3.1%; all p < 0.001). Three-year survival in PAH and non-PAH differed significantly (82.8% vs. 73.3%; p = 0.001). In the Argentine RECOPILAR registry, the clinic-epidemiologic profile was that of advanced-stage disease. Diagnostic workups and therapeutics interventions, including use of specific therapy for PAH, were consistent with current recommendations. Despite delays in diagnosis, survival was aligned with other contemporary registries.

La epidemiología de la hipertensión pulmonar (HP), especialmente la arterial (HAP), no ha sido evaluada en nuestro país, por lo cual no existe un parámetro de referencia para establecer la representatividad de esta información en el orden nacional. El presente registro representa el primer esfuerzo colaborativo para una base de conocimiento de esta enfermedad, incluyendo 5 sociedades científicas que representan a distintas especialidades médicas (pediatría, reumatología, neumonología y cardiología) con datos de 23 provincias argentinas. Los sujetos se agruparon (1-5) de acuerdo con la clasificación de Niza de 2013. El seguimiento se completó en 583 pacientes (93%) un año después del final de la inscripción. Se incluyeron 627 pacientes (edad media, 50.8 ± 18 años; mujeres, 69.2%). Los casos incidentes representaron el 53%. La clase funcional III-IV representaba 69% en el momento del diagnóstico y 33.4% en el momento de la inclusión. Las manifestaciones clínicas fueron disnea (81.8%), fatiga (54.1%), síncope (10.8%), dolor torácico (14.7%), palpitaciones (20.9%) e insuficiencia cardíaca (20.4%). Las tasas de uso de terapias específicas en la hipertensión arterial pulmonar (HAP) frente al grupo sin HAP fueron del 80.5% frente al 40.8%. La supervivencia a tres años en los subconjuntos de HAP y no HAP difirió significativamente (82.8% vs. 73.3%; p = 0.001). En el registro RECOPILAR argentino, que aborda principalmente la HAP, el perfil clínico-epidemiológico fue el d e una enfermedad en estadios avanzados. El diagnóstico y las intervenciones terapéuticas, incluido el uso de terapia específica para la HAP, fueron consistentes con las recomendaciones actuales.
