We aimed to evaluate the prognostic value of HR recovery in functional improvement among adults with severe aortic stenosis undergoing percutaneous aortic valve implantation (TAVI). Methods: We performed a 6 min walk test (6MWT) in 93 individuals before TAVI and 3 months after the procedure. The change in walking distance was calculated. During the pre-TAVI 6MWT, we analyzed the differences between baseline HR, HR at the end of the test, and HR at the 1st, 2nd, and 3rd minute of recovery. Results: After 3 months, 6MWT distances improved by 39 \u00b1 63 m and reached a total of 322 \u00b1 117 m. Multiple linear regression proved the differences between HR after 2 min of recovery and baseline HR in pre-TAVI after a 6MWT was the only significant predictor of waking distance improvement during follow-up. Conclusions: Our study suggests that analysis of HR recovery after a 6MWT may be a helpful and easy parameter to assess improvements in exercise capacity after TAVI. This simple method can help to identify patients in whom no significant benefit in functional improvement can be expected despite successful valve implantation.<\/jats:p>","DOI":"10.3390\/ijerph20054270","type":"journal-article","created":{"date-parts":[[2023,2,28]],"date-time":"2023-02-28T02:28:09Z","timestamp":1677551289000},"page":"4270","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Early Heart Rate Recovery after a 6-min Walking Test Predicts Clinical Benefits in Patients after Percutaneous Aortic Valve Implantation"],"prefix":"10.3390","volume":"20","author":[{"given":"Krzysztof Artur","family":"Aleksandrowicz","sequence":"first","affiliation":[{"name":"Department of Physiotherapy, Faculty of Health Sciences, Wroclaw Medical University, 50-367 Wroclaw, Poland"},{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katarzyna Maria","family":"Aleksandrowicz","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz Grzegorz","family":"Witkowski","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"},{"name":"Department of Cardiology, Faculty of Medicine, Institute of Heart Diseases, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Micha\u0142","family":"Kosowski","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"},{"name":"Department of Cardiology, Faculty of Medicine, Institute of Heart Diseases, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piotr","family":"K\u00fcbler","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"},{"name":"Department of Cardiology, Faculty of Medicine, Institute of Heart Diseases, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karolina","family":"Grze\u015bkowiak","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Grzegorz Piotr","family":"Gola\u0144ski","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Damian Janusz","family":"Kulig","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maciej Filip","family":"Rachwalik","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, Faculty of Medicine, Institute of Heart Diseases, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roman","family":"Przybylski","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, Faculty of Medicine, Institute of Heart Diseases, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1699-739X","authenticated-orcid":false,"given":"Krzysztof","family":"Reczuch","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"},{"name":"Department of Cardiology, Faculty of Medicine, Institute of Heart Diseases, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcin","family":"Protasiewicz","sequence":"additional","affiliation":[{"name":"Institute of Heart Diseases, University Hospital, 50-556 Wroclaw, Poland"},{"name":"Department of Cardiology, Faculty of Medicine, Institute of Heart Diseases, Wroclaw Medical University, 50-367 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1686","DOI":"10.1056\/NEJMoa1200384","article-title":"Two-year outcomes after transcatheter or surgical aortic-valve replacement","volume":"366","author":"Kodali","year":"2012","journal-title":"N.
