Abstract
Background. Heart failure is one of the most significant medical problems of our time, which is associated with the increase in the prevalence of the disease over the past decade. The six-minute walk test is a simple, accessible, and informative tool for assessing the physical activity of patients with heart failure. The test results correlate with peak oxygen consumption and can be used to monitor the effectiveness of rehabilitation programs. The aim of the study is to evaluate the effectiveness of the six-minute walk test as a tool for measuring the level of physical activity and functional status in patients with heart failure, and to determine its correlation with clinical indicators and quality of life in this category of patients. Materials and methods. In this study, conducted on the basis of the UMC "Heart Center" Astana, Kazakhstan, private institution "National Laboratory Astana ", data of patients with heart failure of class I-IV according to a special classification were analyzed. The main objective of the study was to evaluate the effectiveness of the test as a tool for monitoring physical activity and functional status of patients. Results. The results showed that the test is a reliable method for assessing the dynamics of physical capabilities and can be used to individualize rehabilitation programs. Conclusion. The 6MWT remains an important component of clinical practice, helping to optimize functional outcomes and improve the quality of life of patients with heart failure.
