          Abstract

          RESUMEN Introducción: El tratamiento con inhibidores de la fosfodiesterasa 5 a pacientes con cardiopatías adquiridas y congénitas, con hipertensión pulmonar, puede mejorar la calidad y pronóstico de vida, tanto en cardiopatías quirúrgicas como no quirúrgicas, con hipertensión pulmonar grave. Objetivos: Analizar los resultados de la monoterapia con sildenafilo en pacientes quirúrgicos y no quirúrgicos, con cardiopatías congénitas y adquiridas e hipertensión pulmonar grave. Método: Estudio descriptivo en 60 pacientes que recibieron sildenafilo para hipertensión arterial pulmonar grave, secundaria a cardiopatías adquiridas izquierdas, congénitas. Se observó: dosis, duración del tratamiento, tolerancia, evolución clínica y ecocardiográfica, clase funcional y tratamiento quirúrgico según resultados del cateterismo cardiaco. Resultados: En el período entre diciembre de 2017 a diciembre de 2018 se operaron con hipertensión arterial pulmonar grave, 20 enfermos con trastornos valvulares cardíacos izquierdos, 8 congénitos y 3 tumores cardíacos primarios, con administración de sildenafilo en dosis de 100 a 150 miligramos diarios. Hubo otros 29 pacientes con cardiopatías, que aunque no eran quirúrgicos, mejoraron su calidad y pronóstico de vida. Conclusiones: Resultó útil la indicación de sildenafilo, para mejorar la calidad y el pronóstico de vida, tanto en pacientes quirúrgicos como no quirúrgicos con cardiopatías e hipertensión pulmonar grave.

          ABSTRACT Introduction: Treatment with phosphodiesterase 5 inhibitors in patients with acquired and congenital heart disease, with pulmonary hypertension, can improve the quality and prognosis of life, both in surgical and non-surgical heart disease, with severe pulmonary hypertension. Objectives: To analyze the results of sildenafil monotherapy in surgical and non-surgical patients, with congenital and acquired heart disease and severe pulmonary hypertension. Method: Descriptive study in 60 patients who received sildenafil for severe pulmonary arterial hypertension, secondary to congenital left acquired heart disease. It was observed: dose, duration of treatment, tolerance, clinical and echocardiographic evolution, functional class and surgical treatment according to cardiac catheterization results. Results: In the period between December 2017 and December 2018, 20 patients with left heart valvular disorders, 8 congenital and 3 primary cardiac tumors, with sildenafil daily administration doses of 100 to 150 milligrams, were operated with severe pulmonary arterial hypertension. There were 29 other patients with heart disease, which although they were not surgical, improved their quality and prognosis of life. Conclusions: The prescription of sildenafil was useful to improve the quality and prognosis of life, both in surgical and non-surgical patients with heart disease and severe pulmonary hypertension.

            Sildenafil citrate therapy for pulmonary arterial hypertension.

            Sildenafil inhibits phosphodiesterase type 5, an enzyme that metabolizes cyclic guanosine monophosphate, thereby enhancing the cyclic guanosine monophosphate-mediated relaxation and growth inhibition of vascular smooth-muscle cells, including those in the lung. In this double-blind, placebo-controlled study, we randomly assigned 278 patients with symptomatic pulmonary arterial hypertension (either idiopathic or associated with connective-tissue disease or with repaired congenital systemic-to-pulmonary shunts) to placebo or sildenafil (20, 40, or 80 mg) orally three times daily for 12 weeks. The primary end point was the change from baseline to week 12 in the distance walked in six minutes. The change in mean pulmonary-artery pressure and World Health Organization (WHO) functional class and the incidence of clinical worsening were also assessed, but the study was not powered to assess mortality. Patients completing the 12-week randomized study could enter a long-term extension study. The distance walked in six minutes increased from baseline in all sildenafil groups; the mean placebo-corrected treatment effects were 45 m (+13.0 percent), 46 m (+13.3 percent), and 50 m (+14.7 percent) for 20, 40, and 80 mg of sildenafil, respectively (P<0.001 for all comparisons). All sildenafil doses reduced the mean pulmonary-artery pressure (P=0.04, P=0.01, and P<0.001, respectively), improved the WHO functional class (P=0.003, P<0.001, and P<0.001, respectively), and were associated with side effects such as flushing, dyspepsia, and diarrhea. The incidence of clinical worsening did not differ significantly between the patients treated with sildenafil and those treated with placebo. Among the 222 patients completing one year of treatment with sildenafil monotherapy, the improvement from baseline at one year in the distance walked in six minutes was 51 m. Sildenafil improves exercise capacity, WHO functional class, and hemodynamics in patients with symptomatic pulmonary arterial hypertension. Copyright 2005 Massachusetts Medical Society.

              Macitentan for the treatment of inoperable chronic thromboembolic pulmonary hypertension (MERIT-1): results from the multicentre, phase 2, randomised, double-blind, placebo-controlled study

              Macitentan is beneficial for long-term treatment of pulmonary arterial hypertension. The microvasculopathy of chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary arterial hypertension are similar.
