BackgroundIncreases in daily physical activity levels is recommended for patients with peripheral artery disease (PAD). However, despite this recommendation, little is known about the physical activity patterns of PAD patients.ObjectiveTo describe the physical activity patterns of patients with symptomatic peripheral artery (PAD) disease.MethodsThis cross-sectional study included 174 PAD patients with intermittent claudication symptoms. Patients were submitted to clinical, hemodynamic and functional evaluations. Physical activity was objectively measured by an accelerometer, and the time spent in sedentary, low-light, high-light and moderate-vigorous physical activities (MVPA) were obtained. Descriptive analysis was performed to summarize patient data and binary logistic regression was used to test the crude and adjusted associations between adherence to physical activity recommendation and sociodemographic and clinical factors. For all the statistical analyses, significance was accepted at p < 0.05.ResultsPatients spent in average of 640 ± 121 min/day, 269 ± 94 min/day, 36 ± 27 min/day and 15 ± 16 min/day in sedentary, low-light, high-light and MVPA, respectively. The prevalence of patients who achieved physical activity recommendations was 3.4%. After adjustment for confounders, a significant inverse association was observed between adherence to physical activity recommendation and age (OR = 0.925; p = 0.004), while time of disease, ankle brachial index and total walking distance were not associated with this adherence criteria (p > 0.05).ConclusionThe patterns of physical activity of PAD patients are characterized by a large amount of time spent in sedentary behaviors and a low engagement in MVPA. Younger patients, regardless of the clinical and functional factors, were more likely to meet the current physical activity recommendations.
Resumo Fundamento: Estudos transversais anteriores demonstraram que a atividade física está associada a menor risco cardiovascular em pacientes com doença arterial periférica (DAP). No entanto, não é possível estabelecer causalidade e estudos com desenho longitudinal são necessários. Objetivo: Analisar as alterações nos parâmetros de risco cardiovascular e níveis de atividade física após 2 anos de acompanhamento em pacientes com DAP sintomática. Métodos: O presente estudo teve início em 2015. Na primeira fase, foram incluídos 268 pacientes. Na segunda fase, após 2 anos (mediana = 26 meses), foram reavaliados 72 pacientes. Parâmetros de risco cardiovascular, como pressão arterial, modulação autonômica cardíaca e rigidez arterial, e níveis de atividade física foram medidos na linha de base e após 2 anos de acompanhamento. A associação entre as alterações delta (valores após 2 anos – valores da linha de base) na atividade física e nos parâmetros cardiovasculares foi analisada por meio de regressão linear múltipla. O nível de significância foi estabelecido em p < 0,05 com DAP. Resultados: Pacientes reduziram seus níveis totais de atividade física em comparação com a linha de base (linha de base = 2.257,6 ± 774,5 versus acompanhamento = 2.041 ± 676,2 min/semana, p = 0,001). Após o acompanhamento, o índice tornozelo-braquial (0,62 ± 0,20 versus 0,54 ± 0,20, p = 0,003) e o desvio padrão de todos os intervalos RR (43,4 ± 27,0 versus 25,1 ± 13,4 ms, p < 0,001) foram menores, enquanto a velocidade da onda de pulso carotídeo-femoral foi maior (9,0 ± 3,0 versus 10,7 ± 3,4 m/s, p = 0,002) em relação aos valores basais. Não observamos associação entre os valores delta dos níveis de atividade física e os parâmetros de risco cardiovascular. Conclusão: Pacientes com DAP tiveram níveis reduzidos de atividade física e comprometimento em relação aos parâmetros de risco cardiovascular após 2 anos de acompanhamento.
