Use of direct oral anticoagulants for chronic thromboembolic pulmonary hypertension

OBJECTIVES: Chronic thromboembolic pulmonary hypertension is one of the most prevalent forms of pulmonary hypertension and is a major complication of acute pulmonary embolism. One mainstay of chronic thromboembolic pulmonary hypertension treatment is lifelong anticoagulation. The recent advent of direct oral anticoagulants for acute pulmonary embolism treatment has provided a viable and effective alternative for treating this condition. However, little is known about the efficacy of this new class of drugs for treating chronic thromboembolic pulmonary hypertension. We aimed to evaluate the safety and efficacy of direct oral anticoagulants in the treatment of chronic thromboembolic pulmonary hypertension. METHODS: A cohort of chronic thromboembolic pulmonary hypertension patients who initiated treatment with direct oral anticoagulants between June 2015 and November 2016 were enrolled in this study. RESULTS: Sixteen patients used rivaroxaban, three used dabigatran and one used apixaban for a mean follow-up of 20.9 months. The mean age was 51 years, and eighteen patients were classified as functional class II/III. Eight patients underwent a pulmonary endarterectomy and exhibited clinical, hemodynamic and functional improvement and currently continue to use direct oral anticoagulants. No episode of venous thromboembolism recurrence was identified during the follow-up period, but there was one episode of major bleeding after a traumatic fall. CONCLUSIONS: Although direct oral anticoagulants appear to be a safe and effective alternative for treating chronic thromboembolic pulmonary hypertension, larger studies are needed to support their routine use.

Definição e classificação da hipertensão pulmonar / Pulmonary hipertension: definition and classification

A hipertensão pulmonar apresentou desenvolvimento bastante significativo nas últimas duas décadas, devido ao maior conhecimento fisiopatológico de suas mais diversas formas. Espelhando esse desenvolvimento, houve evolução da definição assim como do sistema de classificação da hipertensão pulmonar que divide os pacientes em 5 grupos distintos: hipertensão arterial pulmonar (HAP); Hipertensão pulmonar causada por doenças do coração esquerdo; Hipertensão pulmonar causada por doença pulmonar e/ou hipóxia; Hipertensão pulmonar tromboembólica crônica e Hipertensão pulmonar com mecanismos multifatoriais ou não esclarecidos. A classificação adequada dos pacientes é a base para a instituição terapêutica apropriada, particularmente considerando que a evidência atual que sustenta o uso das medicações disponíveis principalmente na doença arterial pulmonar. Sua adoção reforça a necessidade de avaliação diagnóstica abrangente em todos os casos de hipertensão pulmonar...

Pulmonary hypertension showed significant development in the last two decades due to higher pathophysiological knowledge of its various forms. Mirroring these developments, there was evolution of the definition as well as pulmonary hypertension classification system that divides patients into five groups: pulmonary arterial hypertension (PAH); Pulmonary hypertension caused by left heart diseases; Pulmonary hypertension caused by pulmonary disease and / or hypoxia; Chronic thromboembolic pulmonary hypertension and pulmonary hypertension with multifactorial mechanisms or unclear. The appropriate classification of patients is the basis for appropriate therapeutic institution particularly since the current evidence supporting the use of drugs available mainly in the lung artery disease. Its adoption reinforces the need for comprehensive diagnostic evaluation in all cases of pulmonary hypertension...

Impact of a program to promote health and quality of life of elderly / Impacto de um programa de promoção da saúde na qualidade de vida do idoso

Objective: To evaluate the effect on quality of life of elderly people enrolled in the Grupo de Assistência Multidisciplinar ao Idoso Ambulatorial (GAMIA) of the Geriatric Service of the Hospital das Clínicas of the Faculdade de Medicina of Universidade de São Paulo. Methods: In 83 elderly participants of group between 2000 and 2002 the quality of life was assessed by the World Health Organization Quality of Life (WHOQOL-bref) at the beginning and the end of the program. Functionality was assessed by the Katz and Lawton scales and socio-demographic data were obtained from medical charts. Results: Females predominated (79.5%) and overall mean age was 69.30 years. Data analysis showed a reduction in the physical domain of WHOQOL-bref (p = 0.014) and increased psychological health and environment domains (p = 0.029 and p = 0.007 respectively), detecting a trend of increase in social relationships and in general domains (p = 0.062 and p = 0.052 respectively). Conclusions: The clinical evaluation of elderly may have the predominant factor for the deterioration of their perception in the physical domain because of the detection of previously unknown diseases and determination of the use of new drugs. Improvement in psychological health and the environment can be related to psychological and social support that the elderly received from peers and professionals and the benefits of group activities, as well as the upward trend observed in the social relationships and general domains. Participation in a program to promote healthy aging was effective in improving the quality of life of the elderly.

Objetivo: Avaliar os efeitos na qualidade de vida de idosos matriculados no Grupo de Assistência Multidisciplinar ao Idoso Ambulatorial (GAMIA) do Serviço de Geriatria do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Métodos: Nos 83 idosos participantes do grupo entre 2000 e 2002, a qualidade de vida foi avaliada pelo World Health Organization Quality of Life (WHOQOL-bref) no início e no fim do programa. A funcionalidade foi avaliada pelas Escalas de Katz e Lawton e os dados sociodemográficos foram obtidos nos prontuários. Resultados: Houve predomínio do sexo feminino (79,5%) e a média geral de idade foi de 69,30 anos. A análise dos dados mostraram uma redução no domínio físico do WHOQOL-bref (p = 0,014) e a elevação dos domínios psicológico e meio ambiente (p = 0,029 e p = 0,007, respectivamente), detectando-se tendência de elevação nos domínios relações sociais e geral (p = 0,062 e p = 0,052, respectivamente). Conclusões: Como a avaliação clínica desses idosos revelou doenças desconhecidas previamente e determinou a utilização de novos medicamentos, a percepção que os idosos tinham, em relação à sua saúde, pode ter sido o fator preponderante para a piora no domínio físico. A melhora dos domínios psicológico e meio ambiente pode estar relacionada ao suporte psicológico e social que o idoso recebeu dos colegas e profissionais e dos benefícios das atividades em grupo, bem como às tendência de elevação observada nos domínios relações sociais e geral. A participação em um programa de promoção do envelhecimento saudável mostrou-se eficaz na melhora da qualidade de vida do idoso.
