RESUMO
Individuals diagnosed with systemic arterial hypertension (SAH) are considered risk groups for COVID-19 severity. This study assessed differences in cardiac autonomic function (CAF) and functional capacity (FC) in SAH individuals without COVID-19 infection compared to SAH individuals post-COVID-19. Participants comprised 40 SAH individuals aged 31 to 80 years old, grouped as SAH with COVID-19 (G1; n = 21) and SAH without COVID-19 (G2; n = 19). CAF was assessed via heart rate variability (HRV), measuring R-R intervals during a 10-min supine period. Four HRV indices were analyzed through symbolic analysis: 0V%, 1V%, 2LV%, and 2UV%. FC assessment was performed by a 6-min walk test (6MWT). G1 and G2 showed no significant differences in terms of age, anthropometric parameters, clinical presentation, and medication use. G2 exhibited superior 6MWT performance, covering more distance (522 ± 78 vs. 465 ± 59 m, p < 0.05). Specifically, G2 demonstrated a moderate positive correlation between 6MWT and the 2LV% index (r = 0.58; p < 0.05). Shorter walking distances were observed during 6MWT in SAH individuals post-COVID-19. However, the study did not find impaired cardiac autonomic function in SAH individuals post-COVID-19 compared to those without. This suggests that while COVID-19 impacted FC, CAF remained relatively stable in this population.
RESUMO
OBJETIVO: Descrever o estilo de vida de pacientes admitidos em uma unidade coronariana com diagnóstico de infarto agudo do miocárdio. MÉTODOS: Estudo de corte transversal, observacional, realizado entre março e junho de 2012, em um hospital da cidade de Juazeiro (BA). O questionário utilizado foi o FANTASTIC, que é uma ferramenta validada internacionalmente, inclusive no Brasil. O questionário foi aplicado aos pacientes durante os primeiros dias de internação na unidade fechada, e os dados secundários foram coletados nos prontuários. RESULTADOS: Responderam ao questionário 57 pacientes, sendo 63,2% do sexo masculino, com idade média 61,3±10,9 anos e índice de massa corporal médio de 27,0±4,4kg/m2. A média de pontuação pelo questionário foi de 57,2±7,2, e 63,2% apresentaram um "bom" estilo de vida pela classificação previamente padronizada. As mulheres apresentaram um escore de estilo de vida melhor do que os homens (61,1±5,1 pontos versus 55,0±7,3 pontos; p=0,001). Houve menor pontuação nos domínios nutrição, atividade física e tabagismo. CONCLUSÃO: Os pacientes com infarto agudo do miocárdio apresentaram um escore "bom" pelo questionário FANTASTIC. Alguns domínios, no entanto, mostram valores baixos, como atividade física, nutrição e tabagismo.
OBJECTIVE: To describe the lifestyle of patients admitted to a coronary care unit with acute myocardial infarction. METHODS: Observational cohort study, conducted between March and June, 2012, in a hospital of Juazeiro (BA), Brazil. The questionnaire used was FANTASTIC, that is an internationally validated tool, including Brazil. This was administered to patients during the first days in the coronary care unit and the secondary data were collected from the medical records. RESULTS: Fifty-seven patients answered the questionnaire, 63.2% male, mean age 61.3±10.9 years and mean body mass index of 27.0±4.4kg/m2 . Mean score of the questionnaire was 57.2±7.2; and 63.2% had a "good" lifestyle by previously standardized classification. Women had a better lifestyle score than men (61.1±5.1 points versus 55.0±7.3 points; p=0.001) There were lower scores in the areas nutrition, physical activity and smoking questionnaire. CONCLUSION: Acute myocardial infarction patients had a "good" score in the FANTASTIC questionnaire. Some domains, however, were undesirably low: physical activity, nutrition and smoking.
