“…The importance of exercise for cardiac function was addressed by investigators who reported on the safety of the six-minute walk-test for heart transplantation candidates (Cipriano et al)1 and on left ventricular systolic function (Berisha et al) 2. The circulatory response to a 50-meter walk in acute coronary syndrome was presented by Dias et al3 Furtado et al reported on blood pressure measurements during aerobic exercise in cardiac rehabilitation,4 whereas Oliveira et al reported on the effect of the walk test on the length of hospital stay for cardiac surgery patients 5.…”

Research in the field of cardiopulmonary disease in Brazil has been very active in recent decades. The combination of PUBMED, SCieLO, open access and online searching has provided a significant increase in the visibility of Brazilian journals. This newly acquired international visibility has in turn resulted in the appearance of more original research reports in the Brazilian scientific press. This review is intended to highlight part of this work for the benefit of the readers of “Clinics.” We searched through PUBMED for noteworthy articles published in Brazilian medical journals included in the Journal of Citation Reports of the Institute of Scientific Information to better expose them to our readership. The following journals were examined: “Arquivos Brasileiros de Cardiologia,” “Arquivos Brasileiros de Endocrinologia e Metabologia,” “Brazilian Journal of Medical and Biological Reviews,” “Jornal Brasileiro de Pneumologia,” “Jornal de Pediatria,” “Revista Brasileira de Cirurgia Cardiovascular,” “Revista da Associação Médica Brasileira,” Revista da Escola de Enfermagem U.S.P.” and “São Paulo Medical Journal.” These journals publish original investigations in the field of cardiopulmonary disease. The search produced 71 references, which are briefly examined.

“…Several echo-parameters were tested previously 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 for clinical outcome prediction in patients with HF. Different indices were also, proposed as predictors of survival 11 , 12 , 13 , 14 , 15 , 16 , 17 , quality of life 11 , 12 , 13 , 14 , 15 and exercise capacity 22 , 23 , 24 , 25 , 26 in these patients. Six-minute walk test (6-MWT) has been introduced as an accurate tool for assessing exercise capacity in HF patients, being safe, simple to perform and its results can predict clinical outcomes 18 , 19 , 20 , 21 .…”

“…Left ventricular (LV) systolic function indices 22 , 23 and those of global mechanical dyssynchrony 24 , 25 , 26 have been shown to independently predict exercise capacity in HF patients. However, the left atrial (LA) function indices and their relationship with exercise markers have not been completely tested yet in this setting.…”

AimWe aimed in this study to assess the role of left atrial (LA), in addition to left ventricular (LV) indices, in predicting exercise capacity in patients with heart failure (HF).MethodsThis study included 88 consecutive patients (60 ± 10 years) with stable HF. LV end-diastolic and end-systolic dimensions, ejection fraction (EF), mitral and tricuspid annulus peak systolic excursion (MAPSE and TAPSE), myocardial velocities (s′, e′ and a′), LA dimensions, LA volume and LA emptying fraction were measured. A 6-min walking test (6-MWT) distance was performed on the same day of the echocardiographic examination.ResultsPatients with limited exercise performance (≤ 300 m) were older (p = 0.01), had higher NYHA functional class (p = 0.004), higher LV mass index (p = 0.003), larger LA (p = 0.002), lower LV EF (p = 0.009), larger LV end-systolic dimension (p = 0.007), higher E/A ratio (p = 0.03), reduced septal MAPSE (p < 0.001), larger LA end-systolic volume (p = 0.03), larger LA end-diastolic volume (p = 0.005) and lower LA emptying fraction (p < 0.001) compared with good performance patients. In multivariate analysis, only the LA emptying fraction [0.944 (0.898–0.993), p = 0.025] independently predicted poor exercise performance. An LA emptying fraction < 60% was 68% sensitive and 73% specific (AUC 0.73, p < 0.001) in predicting poor exercise performance.ConclusionIn heart failure patients, the impaired LA emptying function is the best predictor of poor exercise capacity. This finding highlights the need for routine LA size and function monitoring for better optimization of medical therapy in HF.

“…The 6MWT is a submaximal exercise test that resembles the patient's daily activities, allowing an objective assessment of the physical condition (6,10,11). It is based on a routine activity, the walk, and easily accepted by the patients (12,13,14).…”

Comparative survey of the six-minute walk test on the treadmill and on the corridor in cardiac patients [I] Estudo comparativo do teste da caminhada de seis minutos na esteira e no corredor em pacientes cardiopatas [A] Benedita Kamily Oliveira Magalhães [a] , Caio César Guimarães de Freitas [b] , Natália Bitar da Cunha Olegario [c] , Framartinho Carlos Silva Araújo [d] , Guilherme Pinheiro Ferreira da Silva [e] [a] Graduate, Universidade de Fortaleza (Unifor), Fortaleza, CE -Brazil, e-mail: kamily2005@hotmail.com [b] Graduate, Universidade de Fortaleza (Unifor), Fortaleza, CE -Brazil, e-mail: caiocesargf@hotmail.com [c] MSc, Universidade de Fortaleza (Unifor), Fortaleza, CE -Brazil, e-mail: nath_bitar@hotmail.com [d] MSc, professor, Universidade de Fortaleza (Unifor), Fortaleza, CE -Brazil, e-mail: araujofram@hotmail.com [e] MSc, professor, Universidade de Fortaleza (Unifor), Fortaleza, CE -Brazil, e-mail: guilhermepinheiro87@hotmail.com [R] 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 (SatO 2 ). Results: It was statistically significant difference in the comparison between the tests for the variables: walked distance, SBP, DBP and SatO 2 (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 SatO 2 with no significant statistical differences. Only the HR presented statistical significance between groups at the end of the tests.
