O impacto da força de preensão manual na força muscular respiratória de pacientes cardiopatas

Abstract

Introduction: Cardiovascular diseases represent a major public health challenge worldwide due to their high prevalence and high treatment costs. Due to their chronic nature, they can compromise other body systems. Objective: To assess the impact of handgrip strength on the respiratory muscle strength of patients with heart disease in a cardiovascular rehabilitation program. Methods: This was a descriptive, observational, cross sectional study with a sample of 35 individuals undergoing cardiovascular rehabilitation. A questionnaire was administered with personal, sociodemographic and health data. Handgrip strength was measured by dynamometry and respiratory muscle strength by manovacuometry. The analysis was carried out using IBM® SPSS® version 21 software, with descriptive statistics. Correlation was assessed using Pearson's correlation test; the significance level adopted was 5%. Results: 68.6% were men; 37.1% were aged between 60 and 69; 71.4% were white; moderate positive associations were found between muscle strength and maximum respiratory pressures. Conclusion: The findings of this study indicate a significant association between handgrip strength and respiratory muscle strength in patients with heart disease. [resumo fornecido pelo autor]
