RESUMO
BACKGROUND: Previous cross-sectional studies have demonstrated that physical activity is associated with lower cardiovascular risk in patients with peripheral artery disease (PAD). However, it is not possible to establish causality, and longitudinal design studies are required. OBJECTIVE: To analyze the changes in cardiovascular risk parameters and physical activity levels after a 2-year follow-up in patients with symptomatic PAD. METHODS: This study started in 2015. In the first phase, 268 patients were included. In the second phase, after 2 years (median = 26 months), 72 patients were re-evaluated. Cardiovascular risk parameters, such as blood pressure, cardiac autonomic modulation, and arterial stiffness, and physical activity levels were measured at baseline and after 2 years of follow-up. Association among delta changes (values from follow-up - baseline) in physical activity and cardiovascular parameters were analyzed by multiple linear regression. The significance level was set at p < 0.05. RESULTS: Patients reduced their total physical activity levels compared to baseline (baseline = 2257.6 ± 774.5 versus follow-up = 2041 ± 676.2 min/week, p = 0.001). After follow-up, ankle-brachial index (0.62 ± 0.20 versus 0.54 ± 0.20, p = 0.003), and standard deviation of all RR intervals (43.4 ± 27.0 versus 25.1 ± 13.4 ms, p < 0.001) were lower, whereas carotid-femoral pulse wave velocity was higher (9.0 ± 3.0 versus 10.7 ± 3.4 m/s, p = 0.002) compared to baseline values. We did not observe any association among delta values of physical activity levels and cardiovascular risk parameters. CONCLUSION: Patients with PAD had reduced physical activity levels and impaired cardiovascular risk parameters during 2-year follow-up.
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.

Introdução e Objetivo: O impacto do câncer em pacientes com DAP sobre nível de atividade física diária, capacidade funcional, função cardiovascular e qualidade de vida ainda não é conhecido, sendo, portanto, o objetivo deste presente estudo. Métodos: Estudo transversal com 299 pacientes. Nível de Atividade física (acelerômetro), capacidade funcional (teste de caminhada de 6 minutos, Handgrip, Short Physical Performance Battery, Walking Impairment Questionnaire-WIQ e o Walking Estimated-Limitation Calculated by History), função cardiovascular (pressão arterial braquial, variabilidade da frequência cardíaca e rigidez arterial) e qualidade de vida (WHOQOL-bref) foram comparados entre os pacientes com DAP com e sem histórico de câncer. Resultados: Pacientes com DAP e câncer (N=27) apresentaram melhor desempenho no domínio da distância e da velocidade do WIQ (21±37 vs 14±26, p=0.036; 29±18 vs 22±15, p=0.022, respectivamente) comparado aos pacientes com DP sem câncer. Os outros parâmetros foram similares entre os grupos. Conclusão: Os pacientes com DAP e câncer apresentaram
Introduction and Objective: The impact of cancer in patients with PAD on the level of daily physical activity, functional capacity, cardiovascular function and quality of life is not yet known, thus being the objective of this present study. Methods: Cross-sectional study with 299 patients. Physical activity level (accelerometer), functional capacity (6-minute walk test, Handgrip, Short Physical Performance Battery, Walking Impairment Questionnaire-WIQ and the Walking Estimated-Limitation Calculated by History), cardiovascular function (brachial blood pressure, variability of heart rate and arterial stiffness) and quality of life (WHOQOL-bref) were compared between patients with PAD with and without a history of cancer. Results: Patients with PAD and cancer (N=27) performed better in the distance and speed domains of the WIQ (21±37 vs 14±26, p=0.036; 29±18 vs 22±15, p=0.022, respectively) compared to PD patients without cancer. The other parameters were similar between groups. Conclusion: Patients with PAD and cancer had better results for subjectively assessed functional capacity.
RESUMO
Objective: To analyze the longitudinal association between mental health and sleep quality in peripheral artery disease (PAD) patients in two periods of the COVID-19 pandemic. Methods: In this longitudinal study, 99 PAD patients were evaluated in two years of COVID-19 pandemic (2020 and 2021). Patients were interviewed by telephone call, and information regarding mental health (anxiety, unhappiness, stress and depression) and sleep quality (sleep change, difficulty to sleep and sleep improvement) were obtained. Patients were divided into: no symptoms (patients that reported no mental health symptoms, n=31, 68.2±9.4 y.o.) and one or more symptoms (patients with at least one mental health symptom, n=68, 68.1±9.4 y.o.). Results: In 2020, mental health symptoms were associated with sleep change (OR=5.018; p=0.020), difficulty to sleep (OR=12.250; p=0.003) and sleep improvement (OR=0.104; p=0.003). In 2021, mental health was associated only with sleep change (OR=3.522; p=0.035). Conclusion: The impact of mental health symptoms on sleep quality of PAD patients was attenuated along the coronavirus pandemic.
Objetivo: Analisar a associação longitudinal entre saúde mental e qualidade do sono em pacientes com doença arterial periférica (DAP) em dois períodos da pandemia de COVID-19. Métodos: Neste estudo longitudinal, 99 pacientes com DAP foram avaliados em dois anos de pandemia de COVID-19 (2020 e 2021). Os pacientes foram entrevistados por telefone, obtendo-se informações sobre saúde mental (ansiedade, infelicidade, estresse e depressão) e qualidade do sono (alteração do sono, dificuldade para dormir e melhora do sono). Os pacientes foram divididos em: sem sintomas (pacientes que não relataram sintomas de saúde mental, n=31, 68,2±9,4 anos) e um ou mais sintomas (com pelo menos um sintoma de saúde mental, n=68, 68,1±9,4 anos). Resultados: Em 2020, os sintomas de saúde mental foram associados à alteração do sono (OR=5,018; p=0,020), dificuldade para dormir (OR=12,250; p=0,003) e melhora do sono (OR=0,104; p=0,003). Em 2021, a saúde mental esteve associada apenas à alteração do sono (OR=3,522; p=0,035). Conclusão: O impacto dos sintomas de saúde mental na qualidade do sono de pacientes com DAP foi atenuado durante a pandemia de coronavírus.
RESUMO
OBJECTIVE: To verify the association of changes on physical activity levels during coronavirus disease 2019 (COVID-19) outbreak of individuals with normal weight and overweight/obesity, and the influence of sex in this relationship. METHODS: This cross-sectional study (survey research) was conducted in Brazil between May 5 and May 17, 2020. Participants (n=1,828 / 1,062 women >18 years) were invited through social media to answer a structured questionnaire via Google Forms. The online assessment included self-reported responses to questions on physical activity, overall health, weight, and height. Binary logistic regression analyzed the relationship between overweight/obesity (body mass index ≥25kg/m2), the impact of COVID-19 on physical activity level, and the influence of sex. RESULTS: Compared to normal weight people, those with overweight/obesity practice less moderate to vigorous physical activity (p<0.001). There were associations between women and men with overweight/obesity and the impact of COVID-19 on the physical activity practice compared to normal weight people, adjusted by age, education level, social isolation, and previous physical activity level (p<0.017). CONCLUSION: The study found an association of weight and changes in physical activity levels. Individuals with overweight/obesity were more likely to have a lower physical activity level during COVID-19 pandemic, regardless of sex.

RESUMO
OBJECTIVE: To examine the impact of hypertension on cardiovascular health in patients with symptomatic peripheral artery disease and to identify factors associated with uncontrolled hypertension. METHODS: A cross-sectional study including 251 patients with symptomatic peripheral artery disease (63.9% males, mean age 67±10 years). Following hypertension diagnosis, blood pressure was measured to determine control of hypertension. Arterial stiffness (carotid-femoral pulse wave velocity) and cardiac autonomic modulation (sympathovagal balance) were assessed. RESULTS: Hypertension was associated with higher carotid-femoral pulse wave velocity, regardless of sex, age, ankle-brachial index, body mass index, walking capacity, heart rate, or comorbidities (ß=2.59±0.76m/s, b=0.318, p=0.003). Patients with systolic blood pressure ≥120mmHg had higher carotid-femoral pulse wave velocity values than normotensive individuals, and hypertensive patients with systolic blood pressure of ≤119mmHg (normotensive: 7.6±2.4m/s=≤119mmHg: 8.1±2.2m/s 120-129mmHg:9.8±2.6m/s=≥130mmHg: 9.9±2.9m/s, p<0.005). Sympathovagal balance was not associated with hypertension (p>0.05). CONCLUSION: Hypertensive patients with symptomatic peripheral artery disease have increased arterial stiffness. Arterial stiffness is even greater in patients with uncontrolled high blood pressure.

ABSTRACT BACKGROUND: Meta-analyses have demonstrated that isometric handgrip training (IHT) decreases blood pressure in hypertensive individuals. Nonetheless, most studies were conducted in laboratory settings and its effects in real-world settings remain unclear. OBJECTIVE: To analyze the effects of IHT on office and ambulatory blood pressure in hypertensive patients attended within primary healthcare. DESIGN AND SETTING: Randomized controlled trial conducted in primary healthcare units within the Family Health Program, Petrolina, Pernambuco, Brazil. METHODS: 63 hypertensive patients (30-79 years old; 70% female) were randomly allocated into IHT or control groups. IHT was performed three times per week (4 x 2 minutes at 30% of maximal voluntary contraction, one-minute rest between bouts, alternating the hands). Before and after the 12-week training period, office and ambulatory blood pressure and heart rate variability were obtained. The significance level was set at P < 0.05 (two-tailed testing) for all analyses. RESULTS: IHT significantly decreased office systolic blood pressure (IHT: 129 ± 4 versus 121 ± 3 mmHg, P < 0.05; control: 126 ± 4 versus 126 ± 3 mmHg, P > 0.05), whereas there was no effect on diastolic blood pressure (IHT: 83 ± 3 versus 79 ± 2 mmHg, P > 0.05; control: 81 ± 3 versus 77 ± 3 mmHg, P > 0.05). Heart rate variability and ambulatory blood pressure were not altered by the interventions (P > 0.05 for all). CONCLUSION: IHT reduced office systolic blood pressure in hypertensive patients attended within primary care. However, there were effects regarding diastolic blood pressure, ambulatory blood pressure or heart rate variability. CLINICALTRIALS.GOV IDENTIFIER: NCT03216317.

BACKGROUND: This study aimed to analyze the effect of frailty on walking capacity and physical activity levels of patients with peripheral artery disease (PAD). METHODS: A cross-sectional study including 216 symptomatic PAD patients (e.g. claudication) was conducted. Moreover, the frailty profile was established, for which six-minute walk test, Walking Impairment Questionnaire (WIQ), and physical activity level were evaluated. RESULTS: Frailty was prevalent in 13.4%, 72.2%, and 14.4% of frail, pre-frail, and not-frail patients, respectively. Walking capacity was lower in frail patients than in not-frail patients (p < 0.024). The domains of distance and speed of WIQ were lower in frail patients than in not-frail patients, and these domains were also lower in pre-frail than in not-frail patients (p < 0.050 for all). The domain of stairs was lower in frail patients than in not-frail and pre-frail patients (p = 0.016). Physical activity levels were similar among groups (p > 0.050). CONCLUSION: Frailty is associated with further walking impairment in patients with PAD.

BACKGROUND: The mechanisms underlying functional impairments in symptomatic PAD patients are controversial and poorly understood. Endothelial dysfunction and arterial stiffness have been proposed as potential mechanisms related to functional impairment in symptomatic PAD patients, however, more studies are needed to confirm these associations. OBJECTIVE: To analyze the association between vascular function and walking impairment in patients with peripheral arterial disease (PAD) and symptoms of claudication. METHODS: This was a cross-sectional study that included 68 patients with symptomatic PAD. All patients underwent an objective (Six-minute walk test [6MWT], 4-meter walk test) and a subjective (Walking Impairment Questionnaire [WIQ]) measurement of walking impairment. Vascular parameters measured were pulse-wave velocity (PWV) and flow-mediated dilation (FMD). Multiple linear regression was performed to investigate the association among walking impairment variables with vascular function parameters. RESULTS: No significant associations between the claudication onset distance (PWV: b=.060, P = 0.842; FMD: b=-.192, P = 0.456), 6MWT (PWV: b=.007, P = 0..975; FMD: b=.090, P = 0.725), WIQ distance (PWV: b=.337, P = 0.117; FMD: b=-.025, P = 0.895) WIQ speed (PWV: b=.320, P = 0.181; FMD: b=-.028, P = 0.497), WIQ stairs (PWV: b=.256, P = 0.204; FMD: b=-.228, P = 0.230), 4-meter usual walk (PWV: b=-.421, P = 0.107; FMD: b=-.338, P = 0.112), 4-meter fast walk (PWV: b=-.496, P = 0.063; FMD: b=-.371, P = 0.086) and vascular function were found. CONCLUSIONS: In symptomatic PAD patients, vascular function is not associated to walking impairment, even when adjusting for comorbid conditions and diabetes.

OBJECTIVE: To describe physical activity habits and barriers for physical activity practice in patients with peripheral artery disease and claudication symptoms during Coronavirus 2019 (COVID-19) pandemic. METHODS: In this cross-sectional survey study, 127 patients with peripheral artery disease (59.8% men; 68±9 years old; and 81.9% had the peripheral artery disease diagnosis ≥5 years old) were included. The physical activity habits and barriers for physical activity practice were assessed through telephone interview using a questionnaire with questions related to: (a) COVID-19 personal care; (b) overall health; (c) physical activity habits; (d) for those who were inactive, the barriers for physical activity practice. RESULTS: Only 26.8% of patients reported practicing physical activity during the COVID-19 pandemic. Exercise characteristics more common among these patients include walking, performed at least 5 days a week, during 31-60 min at light intensity. In contrast, among physically inactive patients, pain, injury or disability (55%), the COVID-19 pandemic (50%), the need to rest due to leg pain (29%), and lack of energy (27%) were the most frequent barriers to physical activity practice. CONCLUSION: The physical activity level of patients with peripheral artery disease is impacted by the COVID-19 pandemic.

BACKGROUND: The Coronavirus 2019 (COVID-19) pandemic has had a negative impact on the population's behavior. In this context, the effect of the COVID-19 pandemic on drug treatment of patients with peripheral arterial disease (PAD) and intermittent claudication (IC) remains unclear. OBJECTIVES: To analyze the impact of the COVID-19 pandemic on drug treatment of patients with PAD and IC. METHODS: In this cross-sectional, observational study, 136 patients with PAD and IC were recruited from our database and answered a questionnaire by telephone involving the following questions: a) precautions related to COVID-19; b) general health status; and c) treatment of diseases. Subsequently, patients were divided into two groups according to difficulty in obtaining their drugs (DOD: difficulty obtaining drugs, or NDOD: no difficulty obtaining drugs) and overall health was compared between groups. RESULTS: Seventeen percent of patients reported difficulties with obtaining drugs during the pandemic. A higher proportion of these patients reported being sadder (56.5% vs. 24.8%, P < 0.01) and having more difficulty sleeping (56.5% vs. 24.8%, P < 0.01) than of the patients in the NDOD group (P <0.01). The groups did not differ in terms of impairment of walking capability, anxiety, stress, or depression (P> 0.05). CONCLUSIONS: A higher proportion of patients in the DOD group reported being sadder and having greater difficulty sleeping compared to the NDOD group during the COVID-19 pandemic.
RESUMO
BACKGROUND: Although 2-min step test (2MST) has been useful in general population, no study has investigated its validity in patients with peripheral artery disease (PAD). OBJECTIVE: To analyze the validity and reliability of the 2MST in patients with PAD and claudication symptoms. METHODS: Twenty-four patients with PAD and claudication symptoms were recruited and performed the 2MST comparing it to the six-minute walk test (6MWT). Test performance, step indicators, and heart rate were measured during the test. Validity was verified using Pearson correlation between the performance of 2MST (number of steps) and 6MWT (distance and number of steps). The reliability was analyzed by the intraclass correlation coefficient and by the limits of agreement of Bland and Altman. RESULTS: A similar performance was observed between the two 2MST (65⯱â¯10 steps vs. 66⯱â¯10 steps, pâ¯=â¯0.43) with a significant intraclass coefficient correlation of 0.945. The bias between tests was of 0.79 steps with the limits of agreement between -9.6 and 11.2 steps. The 90% minimum detectable difference was 3.2 steps. The number of steps in 2MST was significantly correlated with the number of steps in 6MWT (râ¯=â¯0.55, p<0.01). However, the number of steps in 2MST did not correlate with distance in the 6MWT (râ¯=â¯0.26, pâ¯=â¯0.23). The peak heart rate was lower in 2MST compared to 6MWT (p<0.05). CONCLUSION: The 2MST present adequate reliability and validity in patients with symptomatic PAD.

Background: Elevated screen time has been associated with addictive behaviors, such as alcohol and sugar intake and smoking. Considering the substantial increase in screen time caused by social isolation policies, this study aimed to analyze the association of increased screen time in different devices during the COVID-19 pandemic with consumption and increased desire of alcohol, smoking, and sweetened foods in adults. Methods: A sample of 1,897 adults with a mean age of 37.9 (13.3) years was assessed by an online survey, being composed by 58% of women. Participants were asked whether screen time in television, cell phone, and computer increased during the pandemic, as well as how much time is spent in each device. Closed questions assessed the frequency of alcohol and sweetened food consumption, smoking, and an increased desire to drink and smoke during the pandemic. Educational level, age, sex, feeling of stress, anxiety, depression, and use of a screen device for physical activity were covariates. Binary logistic regression models considered adjustment for covariates and for mutual habits. Results: Increased television time was associated with increased desire to drink (OR = 1.46, 95% CI: 1.12; 1.89) and increased sweetened food consumption (OR = 1.53, 95% CI: 1.18; 1.99), while an increase in computer use was negatively associated with consumption of alcohol (OR = 0.68, 95% CI: 0.53; 0.86) and sweetened foods (OR = 0.78, 95% CI: 0.62; 0.98). Increased cell phone time was associated with increased sweetened food consumption during the pandemic (OR = 1.78, 95% CI: 1.18; 2.67). Participants with increased time in the three devices were less likely to consume sweetened foods for ≥5 days per week (OR = 0.63, 95% CI: 0.39; 0.99) but were twice as likely to have sweetened food consumption increased during pandemic (OR = 2.04, 95% CI: 1.07; 3.88). Conclusion: Increased screen time was differently associated with consumption and desire for alcohol and sweets according to screen devices. Increased time in television and cell phones need to be considered for further investigations of behavioral impairments caused by the pandemic.
