    Objective: To evaluate the reliability and reproducibility of self-administration of the 6MWT using a free smartphone APP for step counting. Methods: In the first phase, 83 participants (44 ± 10 years, 27 ± 5 kg/m²) underwent a supervised 6MWT in a 30 m covered runner usinga a triaxial accelerometer and smartphones to compare the total step count (Npac and Npapp). We developed a multiple regression equation to estimate the distance walked on the 6MWT (D6MWT) (R² = 0.609). In the second phase, 25 participants (40 ± 10 years, 27 ± 5 kg/m²) performed the 6MWTsup and two other outdoor 6MWT (D6WMTauto1 and D6MWTauto2) using APP for Npapp counts. Results: Npac was significantly higher than Npapp (mean difference, 58 ± 136 m, p = 0,001). The reliability among these measures was weak (intraclass correlation coefficient (ICC), 0,04: 95% confidence interval (95%CI), -0,52-0,40, coefficient of variation (CV) = 42,9%). The limits of agreement between measures were also not adequate (46%), with mean difference of -8,7%. D6MWTauto2 was not significantly different from D6MWTauto1 (mean difference, 1,94 ± 30,27 m, p = 0,761). The confidence limits were lower 10% with an average difference of 0,2%. The reliability among measurements was also excellent (ICC, 0,91; 0,81-0,96; CV 6,4%). D6MWTauto1 was not significantly different from D6MWTsup (1,68 ± 61 m; p = 0,894) with moderate reliability was not significantly different from D6MWT (ICC, 0,75; 0,42-0,89; CV = 27,5%). Acceptable confidence limits (19%) with significant negative correlation between mena difference and mean values. The difference between D6MWTauto2 and D6MWTsup was not significant (3,64 ± 60,57 m, p = 0,766), good reliability (CCI = 0,79; 0,50-0,91; CV = 6%). Confidence limits lower than 19% with significant negative correlation. Conclusion: The 6MWTauto is valid and presents excellent reliability and reproducibility. Our results suggest that the use of 6MWT in people with higher CAR, when necessary, should be used with caution.

    Existe Diferença Na Distância Entre O Primeiro E O Segundo Teste De Caminhada De Seis Minutos Em Pacientes Hospitalizados Com Infarto Agudo Do Miocárdio?

    The 6-Minute Walk Test (Tc6') Is A Widely Used Instrument To Evaluate The Functional Capacity Of Patients With Heart Disease, Besides Stratifying The Prognosis And Therapeutic Efficacy. Repetition Of The Test Is Recommended As Standard Practice, With A One-Hour Rest Interval Between Tests. Studies Dedicated To Outpatient Assessment In Several Populations Have Shown That When Tests Are Performed More Than Once The Distance May Be Higher In The Second Test. However, In The Case Of Patients After Hospitalized Acute Myocardial Infarction (Ami), There Are No Reports In The Literature About The Need To Repeat The Test Applied Early. According To The Literature, The Functional Capacity Of These Patients Is Influenced By The Coronary Microcirculation, And There Is No Record Of The Relation Between The Coronary Artery Culprit For The Event (Infarct-Related Artery) And The Need Of Two Tests On The Tc6'. Objective: To Evaluate If There Is Difference In The Distance Covered Between The First And Second Tc6'; And To Inves
