Physical Exercise in the Management of Erectile Dysfunction in Patients with Heart Failure

Erectile dysfunction (ED) is a highly prevalent problem that affects the quality of life, prognosis and survival of patients with heart failure (HF). In the management of ED, physical exercise is a therapeutic strategy that reduces disease-related symptoms and optimizes drug use. However, the repercussions of physical exercise on ED in individuals with HF still need to be elucidated. In this sense, the objective of this study was to evaluate the effects of physical exercise on erectile function (EF) in HF patients. This was a systematic review conducted according to PRISMA guidelines. Patients with HF, male and ejection fraction ≤ 45% were submitted to physical exercise of different modalities. The search for scientific articles was conducted in the electronic databases (PubMed, LILACS, Cochrane-Library, Science Direct) from the inception until October 2018, according to the MeSH dictionary descriptors, which were suitable for all databases. Results: Three studies were analyzed, includinng 99 male subjects, age ranging from 53 years (± 7.48) to 58 years (± 12). Seventy subjects were submitted to a physical exercise program and 29 were in the control group. In all studies, physical exercise showed positive results in the management of ED regardless of erectile dysfunction (ED) classification status and intensity of exercise used. It was concluded that physical exercise of different intensities was considered an effective therapeutic intervention to improve EF in individuals with HF and ED

Validação do Índice Internacional de Função Erétil (IIFE) para uso no Brasil / Validation of the International Index of Erectile Function (IIFE) for use in Brazil

FUNDAMENTO: O Índice Internacional de Função Erétil tem sido proposto como método de avaliação da função sexual, auxiliando no diagnóstico e na classificação da disfunção erétil. No entanto, não foi realizada a validação do IIFE para a língua portuguesa. OBJETIVO: Validar o Índice Internacional de Função Erétil em pacientes portadores de doenças cardiopulmonares e metabólicas. MÉTODOS: A amostra foi composta por 108 participantes portadores de doenças cardiopulmonares e metabólicas de dois programas de reabilitação cardiopulmonar e metabólica (RCPM) do sul do Brasil. A avaliação da clareza do instrumento foi realizada por meio de escala com variação de 0-10, a validação de construto foi realizada pela análise fatorial confirmatória (KMO = 0,85, Barllet p < 0,001), a consistência interna foi analisada pelo alfa de Cronbach. Foram analisados, ainda, os preceitos de reprodutibilidade e confiabilidade interavaliadores por meio do teste reteste. RESULTADOS: Os itens foram julgados muito claros, com médias superiores a 9. A consistência interna resultou em 0,89. A maioria das questões relacionou-se corretamente com seus respectivos domínios, com exceção das três questões do domínio satisfação sexual e uma questão relacionada à função erétil. Os itens apresentaram excelente estabilidade de medida e concordância substancial quase perfeita. CONCLUSÃO: Demonstrou-se que o IIFE é válido e bem compreendido por pacientes que participam de programa de reabilitação cardiopulmonar e metabólica.

BACKGROUND: The International Index of Erectile Function has been proposed as a method for assessing sexual function assisting the diagnosis and classification of erectile dysfunction. However, IIEF was not validated for the Portuguese language. OBJECTIVE: Validate the International Index of Erectile Function in patients with cardiopulmonary and metabolic diseases. METHODS: The sample consisted of 108 participants of to Cardiopulmonary and Metabolic program Rehabilitation (CPMR) in southern Brazil. The clarity assessment of the instrument was performed using a scale ranging from zero to 10. The construct validity was carried out by confirmatory factor analysis (KMO = 0.85; Barllet p < 0.001), internal consistency by Cronbach's alpha and reproducibility and interrater reliability via the test retest method. RESULTS: The items were considered very clear with averages superior to 9. The internal consistency resulted in 0.89. The majority of items related correctly with their domains, with exception of three questions from sexual satisfaction domain, and one from erectile function. All items showed excellent stability of measure and substantial to almost perfect agreement. CONCLUSION: The present study showed that the IIEF is valid and reliable for use in participants of a cardiopulmonary and metabolic rehabilitation program.
