ABSTRACT Introduction: Participants in cardiac rehabilitation programs have low adherence to their sessions, which makes extremely important to recognize the barriers that cause non-adherence, identifying whether the type of service and level of adherence influence these barriers. Methods: This is a cross-sectional observational study, in which 220 individuals (66.80±11.59 years) of both genders who are members of public and private exercise-based cardiac rehabilitation programs participated. The volunteers were divided according to the level of adherence, considering patients with low adherence (PLA) those with < 70% of attendance and high adherence (PHA) those with > 70%. Then, initial evaluation, Cardiac Rehabilitation Barriers Scale, analysis of socioeconomic level, Hospital Anxiety and Depression Scale, and Mini-Mental State Examination were applied. Results: Higher total barriers were found in PLA in the public service compared to PHA in the private service (P=0.023). In the subscale "perceived need", PHA in the public service showed higher values than PLA and PHA in the private service (P≤0.001). The "access" barrier was higher for PHA in the public service when compared to PHA in the private service (P=0.024). PHA in the public service exhibited a higher barrier regarding questions about distance, transportation problems, cost, and time constraints. Conclusion: The public program presents higher barriers in the questions and categories compared to the private program, mainly the PHA. Furthermore, there are differences in the profile of the participants regarding socioeconomic and anxiety levels, treatment time, ethnicity, and city where they live.

ABSTRACT BACKGROUND: Cardiac rehabilitation (CR) barriers are well-understood in high-resource settings. However, they are under-studied in low-resource settings, where access is even poorer and the context is significantly different, including two-tiered healthcare systems and greater socioeconomic challenges. OBJECTIVE: To investigate differences in characteristics of patients attending publicly versus privately funded CR and their barriers to adherence. DESIGN AND SETTING: Observational, cross-sectional study in public and private CR programs offered in Brazil. METHODS: Patients who had been attending CR for ≥ 3 months were recruited from one publicly and one privately funded CR program. They completed assessments regarding sociodemographic and clinical characteristics and the CR Barriers Scale. RESULTS: From the public program, 74 patients were recruited, and from the private, 100. Participants in the public program had significantly lower educational attainment (P < 0.001) and lower socioeconomic status (P < 0.001). Participants in the private program had more cognitive impairment (P = 0.015), and in the public program more anxiety (P = 0.001) and depressive symptoms (P = 0.008) than their counterparts. Total barriers among public CR participants were significantly higher than those among private CR participants (1.34 ± 0.26 versus 1.23 ± 0.15/5]; P = 0.003), as were scores on 3 out of 5 subscales, namely: comorbidities/functional status (P = 0.027), perceived need (P < 0.001) and access (P = 0.012). CONCLUSION: Publicly funded programs need to be tailored to meet their patients' requirements, through consideration of educational and psychosocial matters, and be amenable to mitigation of patient barriers relating to presence of comorbidities and poorer health status.

ABSTRACT Background: Parkinson's disease (PD) produces autonomic changes, indicating lower parasympathetic modulation and global variability, but these changes need further studying regarding geometric methods. Objective: To investigate the autonomic modulation in individuals with PD using heart rate variability (HRV) indices obtained through geometric methods. Methods: This is a cross-sectional study that assessed 50 individuals, split into two groups: PD group (PDG; n=26; 75.36±5.21 years) and control group (CG; n=24; 75.36±5.21 years). We evaluated the autonomic modulation by measuring the heart rate beat-to-beat for 30 min with the individual in supine rest using a heart rate monitor and assessed geometric indices (RRtri, TINN, SD1, SD2, SD1/SD2 ratio, and qualitative analysis of the Poincaré plot). Results: Significant reductions were found in RRtri, TINN, SD1, and SD2 indices among PDG compared to CG. Regarding the SD1/SD2 ratio, no significant changes were detected between the groups. The Poincaré plot demonstrated that individuals with PD had lower beat-to-beat dispersion in RR intervals, in addition to greater long-term dispersion of RR intervals compared to CG. Conclusions: The results suggest a reduction in the parasympathetic autonomic modulation and global variability in individuals with PD compared to controls, regardless of sex, age, and body mass index.

RESUMO Introdução: A doença de Parkinson (DP) produz alterações autonômicas, que indicam menor modulação parassimpática e variabilidade global, mas que devem ser investigadas quanto aos métodos geométricos. Objetivo: Investigar a modulação autonômica em indivíduos com DP, por meio de índices de variabilidade da frequência cardíaca (VFC) obtidos pelos métodos geométricos. Métodos: Estudo transversal, no qualforam avaliados 50 voluntários, divididos em dois grupos: o grupo doença de Parkinson (GDP; n=26; 75,36±5,21 anos) e o grupo controle (GC; n=24; 75,36±5,21 anos). Para a avaliação da modulação autonômica a frequência cardíaca foi captada batimento a batimento por meio de um cardiofrequencímetro com os indivíduos em decúbito dorsal por 30 min e índices geométricos da VFC foram avaliados (RRtri, TINN, SD1, SD2 e plot de Poincaré). Resultados: Houve reduções nos índices RRtri, TINN, SD1 e SD2 para o GDP em comparação ao GC. Para a relação SD1/SD2, diferenças significantes não foram observadas entre os grupos. O plot de Poincaré mostrou que indivíduos com DP têm menor dispersão batimento a batimento dos intervalos RR, bem como maior dispersão dos intervalos RR a longo prazo em relação ao GC. Conclusão: Os resultados sugerem haver diminuição da modulação autonômica parassimpática e da variabilidade global em indivíduos com DP em relação a indivíduos sem a doença, as quais são independentes de sexo, idade e índice de massa corporal.

This study examined the relationship between resting heart rate (RHRr) and anthropometric, metabolic and hemodynamic parameters in subjects aged 80 years and over. One hundred thirteen individuals were divided into two groups (RHR:<66 beats/min and ≥66 beats/min). Anthropometric parameters (weight, height, body mass index and waist circumference (WC) were measured. Hemodynamic parameters (systolic (SBP) and diastolic (DBP) pressure) were measured and pulse pressures (PP) were obtained. Metabolic parameters were fasting blood glucose, triglycerides and total cholesterol. In elderly aged 80 and over, RHR influenced the changes observed in DBP, PP and triglycerides. Additionally, subjects with RHR≥66 beats/min had higher DBP, glucose, total cholesterol and lower PP as compared with elderly with RHR<66 beats/min. Men demonstrated greater weight, height, and WC than women while women had higher percentage of body fat, trunk fat, and higher total cholesterol. Thus, subjects with 80 years old and over who present RHR≥66 have higher DBP and lower PP and heart rate variability compared with the elderly with RHR<66.

PURPOSE: this study evaluated the effects of a multidisciplinary program on autonomic modulation in overweight or obese children and adolescents. METHODS: fifteen individuals with 10,93 ± 2,28 years were submitted to autonomic evaluation using heart rate variability before and after a program based on physical exercises for three months, three times a week, 60 minutes per session and psychological and nutritional counseling. Data was analyzed using the paired t-test or Wilcoxon test and the level of significance was set at P < 0.05. RESULTS: multidisciplinary program was able to promote benefits in autonomic modulation observed thought temporal (SDNN: 39,96 ± 10,33 x 49,44 ± 12,31; p = 0,019; rMSSD: 28,97 ± 11,50 x 37,26 ± 11,17; p = 0,018), spectral (LFnu: 64,49 ± 12,21 x 56,74 ± 11,18; p = 0,014; HFnu: 35,50 ± 12,21 x 43,25 ± 11,18; p = 0,014) and geometrical (SD1: 20,51 ± 8,13 x 26,36 ± 7,90; p = 0,018 SD2: 52,31 ± 13,04 x 64,58 ± 16,33; p = 0,031) indices in overweigh and obese children and adolescents. Also, after the intervention there was a reduction on resting heart rate (88,53 ± 9,24 x 83,09 ± 7,93; p = 0,023) and there were changes in the classification of overweigh 26,67% x 46,66% and obesity 73,33% x 53,33%, although not significant changes in body mass index. CONCLUSIONS: exercise program together with nutritional and psychological counseling is able to promote benefits in autonomic modulation in children and adolescents who are overweight or obese.

OBJETIVO: avaliar a influência de um programa multidisciplinar na modulação autonômica de crianças e adolescentes com sobrepeso e obesidade. MÉTODO: quinze indivíduos com 10,93 ± 2,28 anos foram submetidos a avaliação da modulação autonômica por meio da variabilidade da frequência cardíaca antes e após um programa de atividades físicas conduzido por três meses, com frequência de três vezes na semana por 60 minutos cada sessão, associado com aconselhamento nutricional e psicológico. Para análise estatística foi utilizado teste T para dados pareados ou teste de Wilcoxon com significância de p < 0,05. RESULTADOS: o programa multidisciplinar foi capaz de influenciar positivamente a modulação autonômica o que pode ser observado por índices temporais (SDNN = 39,96 ± 10,33 vs. 49,44 ± 12,31; p = 0,019; rMSSD = 28,97 ± 11,50 vs. 37,26 ± 11,17; p = 0,018), espectrais (LFnu = 64,49 ± 12,21 vs. 56,74 ± 11,18; p = 0,014; HFnu = 35,50 ± 12,21 vs. 43,25 ± 11,18; p = 0,014) e geométricos (SD1 = 20,51 ± 8,13 vs. 26,36 ± 7,90; p = 0,018; SD2 = 52,31 ± 13,04 vs. 64,58 ± 16,33; p = 0,031) de variabilidade em crianças e adolescentes com sobrepeso e obesidade. Adicionalmente, após a intervenção houve redução da frequência cardíaca de repouso (88,53 ± 9,24 vs. 83,09 ± 7,93; p = 0,023) e mudanças na classificação da obesidade dos indivíduos para sobrepeso 26,67% vs. 46,66% e obesidade 73,33% vs. 53,33%. Apesar disso, não houve diferença significante no índice de massa corporal. CONCLUSÕES: um programa de exercícios associado com aconselhamento nutricional e psicológico foi capaz de promover benefícios na modulação autonômica em crianças e adolescentes com sobrepeso e obesidade.
