This was a cross-sectional study with stable CAD patients, which performed a cardiopulmonary exercise test (CPET) on a treadmill and a 6-min walk test (6MWT) on nonconsecutive days. The accuracy of agreement between HRVT1 and HR6MWT was evaluated by Bland\u2013Altman analysis and Lin\u2019s concordance correlation coefficient (rc), mean absolute percentage error (MAPE), and standard error of estimate (SEE). Seventeen stable CAD patients on \u03b2-blockers treatment (male, 64.7%; age, 61\u00b1 10 years) were included in data analysis. The Bland\u2013Altman analysis revealed a negative bias of -0.41 \u00b1 6.4 bpm (95% limits of agreements, -13 to 12.2 bpm) between HRVT1 and HR6MWT. There was acceptable agreement between HRVT1 and HR6MWT (rc = 0.84; 95% confidence interval, 0.63 to 0.93; study power analysis= 0.79). The MAPE of the HR6MWT was 5.1% and SEE was 6.6 bpm. The ratio HRVT1\/HRpeak and HR6MWT\/HRpeak from CPET were not significantly different (81%\u00b1 5% vs. 81%\u00b1 6%, P= 0.85); respectively. There was a high correlation between HRVT1 and HR6MWT (r= 0.85, P&lt; 0.0001). Finally, the results of the present study demonstrate that there was an acceptable agreement between HRVT1 and HR6MWT in CAD patients on \u03b2-blockers treatment and suggest that HR6MWT may be useful to prescribe and control aerobic exercise intensity in cardiac rehabilitation programs.<\/jats:p>","DOI":"10.12965\/jer.2142488.244","type":"journal-article","created":{"date-parts":[[2021,10,26]],"date-time":"2021-10-26T23:49:35Z","timestamp":1635292175000},"page":"362-368","update-policy":"https:\/\/doi.org\/10.12965\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Agreement between heart rate at first ventilatory threshold on treadmill and at 6-min walk test in coronary artery disease patients on \u03b2-blockers treatment"],"prefix":"10.12965","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0758-3467","authenticated-orcid":true,"given":"Leonardo","family":"Calegari","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Igor","family":"Moreira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrei","family":"Falkowski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Basileu Caon","family":"Reol\u00e3o","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marlus","family":"Karsten","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu\u00eds Fernando","family":"Deresz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5137","published-online":{"date-parts":[[2021,10,26]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.cd001800.pub3"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.physio.2011.11.003"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijnurstu.2009.10.001"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1590\/s1413-35552012005000122"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1177\/1559827615625482"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1097\/01.hjr.0000189809.99353.76"},{"key":"ref7","first-page":"943","volume-title":"Brazilian cardiovascular rehabilitation guideline - 2020","author":"Carvalho","year":"2020"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.rehab.2016.01.011"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.rehab.2013.09.003"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1097\/00008483-200511000-00009"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1177\/2047487313500214"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjmed.2014.02.008"},{"key":"ref13","first-page":"873","volume-title":"Exercise standards for testing and training: a scientific statement from the American Heart Association","author":"Fletcher","year":"2013"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2003.11.037"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1249\/mss.0000000000001284"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1093\/eurjpc\/zwab007"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1177\/2047487319859450"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00150314"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1378\/chest.09-2624"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehz425"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.2307\/2532051"},{"key":"ref22","first-page":"249","volume-title":"Standards for the use of cardiopulmonary exercise testing for the functional evaluation of cardiac patients: a report from the Exercise Physiology Section of the European Association for Cardiovascular Prevention and Rehabilitation","author":"Mezzani","year":"2009"},{"key":"ref23","first-page":"92","volume-title":"Are first ventilatory threshold and 6-minute walk test heart rate interchangeable?
