Impacto da atividade física na qualidade subjetiva do sono em cardiopatas: uma série de casos

Abstract

Cardiovascular diseases (CVDs) are conditions of multifactorial origin, with the presence of modifiable and non-modifiable factors. Among these factors, sleep is an important emerging factor in cardiovascular health; however, the benefits of its association with physical exercise are still uncertain. Therefore, the objective of this study was to analyze the characteristics of sleep and physical activity associated with sociodemographic variables in two distinct groups: one with individuals undergoing cardiovascular rehabilitation (n=13) and another with participants who had been discharged for a maximum of 2 years (n=10). Through a series of cases with a qualitative-quantitative approach, data were collected using the IPAQ and PSQI-BR questionnaires and statistically analyzed using Spearman's correlation. The results show that sleep quality is predominantly low in both groups; and in the post-discharge group, there is a greater decline in physical activity levels and greater adoption of sedentary behavior. Therefore, in this study, individuals in rehabilitation, despite having a more active lifestyle, were mostly classified as having slightly worse sleep quality when compared to those who had already been discharged. However, after rehabilitation, a low level of physical activity is prevalent, highlighting the difficulty of maintaining an active lifestyle after the program.
