Abstract

Introduction The six minute walk test (6MWT) is considered an important tool in the evaluation of physical capacity, monitoration and the effectiveness of treatment in cardiac patients.Objective To compare the 6MWT on the treadmill and corridor in cardiac patients.Methods Participated 24 cardiac patients, being 12 male and 12 female with 56.7 ± 12.7 years age average, submitted to the six-minute walk test on the treadmill (6MWTT) and on the corridor (6MWTC) in an interval of seven days. The analyzed variables were: walked distance, respiratory rate (RR), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and oxygen saturation (SatO2).Results It was statistically significant difference in the comparison between the tests for the variables: walked distance, SBP, DBP and SatO2 (p > 0.05). The only statistically significant variable was the HR after the test application (p = 0.03).Conclusion After the two tests application, there was similarity in the variables: walked distance, SBP, DBP and SatO2 with no significant statistical differences. Only the HR presented statistical significance between groups at the end of the tests.

Highlights

The six minute walk test (6MWT) is considered an important tool in the evaluation of physical capacity, monitoration and the effectiveness of treatment in cardiac patients
The following hemodynamic parameters of the patients were verified at rest: respiratory rate (RR), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and oxygen saturation (SpO2)
Heart rate was the only variable that presents significant difference after the application of the 6MWT using treadmill (6MWTT) when compared to the 6MWTC (p = 0.03) (Table 2)

Summary

Introduction

The six minute walk test (6MWT) is considered an important tool in the evaluation of physical capacity, monitoration and the effectiveness of treatment in cardiac patients. Results: It was statistically significant difference in the comparison between the tests for the variables: walked distance, SBP, DBP and SatO2 (p > 0.05). Conclusion: After the two tests application, there was similarity in the variables: walked distance, SBP, DBP and SatO2 with no significant statistical differences. According to the Brazilian Ministry of Health, there are approximately 260,000 myocardial infarcts (MI) per year [1] The consequence of this fact is a significant increase in health care costs, including hospitalization, medicines, laboratory tests, outpatient visits and early retirement [2]. The patients with CD report more subjective dyspnea sensation when compared to healthy subjects of similar age and weight These patients present atrophy and respiratory muscles deconditioning, culminating in physical and social limitations witch decreases the quality of life of these individuals [4]
