“…However, the effects of ACT on the walking capacity in other conditions (e.g., walking fast, climbing stairs, the six-minute walking test, etc), as well as on the other parameters of functional capacity, such as strength and balance, are still unclear. This is relevant, since these patients also present alterations in different parameters of functional capacity [ 10 , 27 , 29 , 39 ].…”

Background Arm-crank exercise training (ACT) is an alternative exercise strategy for patients with symptomatic peripheral artery disease (PAD) due to the attenuation of pain symptoms during the exercise, as well as the benefits to functional capacity. Purpose The aim of this study is to describe the study protocol to analyze the effects of ACT exercise on cardiovascular function, functional capacity, cognition and quality of life in patients with symptomatic PAD. Methods This is a three-armed randomized, prospective, single-blind data collection, single-center, controlled study enrolling 45 patients with symptomatic PAD who will be randomized into 3 intervention groups: walking training (WT), ACT and control group. The WT and ACT will perform 2 sessions/week, 15 to 10 sets of 2 to 5 minutes at values of 13 to 15 on the Borg scale. Before and after 12 weeks of intervention, cardiovascular function (ambulatory blood pressure, office blood pressure, central blood pressure, heart rate variability, arterial stiffness and vascular function), functional capacity (six-minute walk test, 2 minute step test, handgrip test, Walking impairment questionnaire, Walking estimated limitation calculated by history, Baltimore activity scale for intermittent claudication, and short physical performance battery), cognition (executive function and memory), and quality of life (vascular quality of life questionnaire and World Health Organization Quality of Life) will be assessed. Results This is the first trial to evaluate the effects of ACT on regulatory mechanisms of the cardiovascular system in PAD patients. If the results are as expected, they will provide evidence the ability of ACT to promote cardiovascular benefits in the symptomatic PAD population.

“…Six-minute walk test . The six-minute walk test will be performed along a 30-meter-long corridor, as previously described [ 26 , 27 ]. Briefly, patients will be encouraged to “walk at their usual pace for six-minutes and cover as much ground as possible” and rest if necessary.…”

“…The 6MWT total distance was defined as the maximum distance achieved by the patients at the end of the test. In addition, the 6MWT total distance was relativised based on the results of 6MWT performed by healthy individuals using Brito's et al equation [21], previously used in patients with PAD [22].…”

Introduction The risk of malnutrition is an important predictor of functional capacity in the elderly population. However, whether malnutrition is associated with functional capacity in patients with peripheral artery disease (PAD) is poorly known. Purpose To analyse the association between the risk of malnutrition and functional capacity in patients with PAD. Methods This cross-sectional study included 135 patients with PAD of both genders, ≥50 years old, with symptomatic PAD (Rutherford stage I to III) in one or both limbs and with ankle-brachial index ≤0.90. The risk of malnutrition was assessed by the short form of the Mini Nutritional Assessment-Short Form and patients were classified as having normal nutritional status (n = 92) and at risk of malnutrition (n = 43). Functional capacity was objectively assessed using the six-minute walking test (6MWT, absolute maximal distance and relativized and expressed as a percentage of health subjects), short-physical performance battery (SPPB, balance, gait speed and the sit and stand test) and the handgrip test, and subjectively, using the Walking Impairment Questionnaire and Walking Estimated-Limitation Calculated by History. The association between the risk of malnutrition and functional capacity was analysed using bivariate and multivariate logistic regression adjustments for gender, age, ankle-brachial index, body mass index, use of statins, coronary arterial disease and stroke. For all statistical analyses, significance was accepted at p<0.05. Results Thirty-two per cent of our patients were classified with a risk of malnutrition. The risk of malnutrition was associated with the absolute 6MWT total distance (OR = 0.994, P = 0.031) relative 6MWT total distance (OR = 0.971, P = 0.038), lowest SPPB total score (OR = 0.682, P = 0.011), sit and stand (OR = 1.173, P = 0.003) and usual 4-meter walk test (OR = 1.757, P = 0.034). Conclusion In patients with PAD, the risk of malnutrition was associated with objective measurements of functional capacity.

“…Foi realizado um teste de caminhada de 6 minutos em um corredor de 30 metros de comprimento, seguindo o protocolo descrito anteriormente. 13 Dois cones foram colocados a 30 metros de distância e os pacientes foram orientados a caminhar o maior número possível de voltas ao redor dos cones. Também foram orientados a informar quando sintomas de claudicação (dor, desconforto, cãibras e cansaço) ocorreram para determinar a distância de início da claudicação.…”

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.
