This observational study included 60 patients who underwent cardiac surgery with a complicated postoperative course and with a prolonged intensive care unit stay of more than 72 h. We assessed handgrip and lower-extremity muscle strength and the six-minute walk test (6MWT) distance 3 days after the surgery and at discharge from the hospital. Some patients (53%) additionally underwent a course of neuromuscular electrostimulation (NMES). Two groups of patients were formed: first (6MWT distance at discharge of more than 300 m) and second groups (6MWT distance of 300 m or less). The patients of the second group had less lower-extremity muscle strength and handgrip strength on the third postoperative day, a longer aortic clamping time and a longer stay in the intensive care unit. Independent predictors of decreased exercise tolerance at discharge were body mass index, foot extensor strength and baseline 6MWT distance in the general group, duration of cardiopulmonary bypass in the NMES group and in the general group, and age in the NMES group. Thus, the muscle status on the third postoperative day was one of the independent factors associated with the 6MWT distance at discharge in the general group, but not in patients who received NMES. It is advisable to use these results in patients with complications after cardiac surgery with the use of NMES rehabilitation.<\/jats:p>","DOI":"10.3390\/ijerph19074329","type":"journal-article","created":{"date-parts":[[2022,4,4]],"date-time":"2022-04-04T09:49:41Z","timestamp":1649065781000},"page":"4329","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Factors Determining the Functional State of Cardiac Surgery Patients with Complicated Postoperative Period"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0963-4793","authenticated-orcid":false,"given":"Alexey N.","family":"Sumin","sequence":"first","affiliation":[{"name":"Laboratory of Comorbidity in Cardiovascular Diseases, FSBSI Research Institute for Complex Issues of Cardiovascular Diseases, Sosnovy Blvd. 6, 650002 Kemerovo, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pavel A.","family":"Oleinik","sequence":"additional","affiliation":[{"name":"Laboratory of Comorbidity in Cardiovascular Diseases, FSBSI Research Institute for Complex Issues of Cardiovascular Diseases, Sosnovy Blvd. 6, 650002 Kemerovo, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4420-4350","authenticated-orcid":false,"given":"Andrey V.","family":"Bezdenezhnykh","sequence":"additional","affiliation":[{"name":"Laboratory of Comorbidity in Cardiovascular Diseases, FSBSI Research Institute for Complex Issues of Cardiovascular Diseases, Sosnovy Blvd. 6, 650002 Kemerovo, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia A.","family":"Bezdenezhnykh","sequence":"additional","affiliation":[{"name":"Laboratory of Comorbidity in Cardiovascular Diseases, FSBSI Research Institute for Complex Issues of Cardiovascular Diseases, Sosnovy Blvd. 6, 650002 Kemerovo, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"386","DOI":"10.1097\/MCC.0000000000000319","article-title":"Postoperative complications of patients undergoing cardiac surgery","volume":"22","author":"Ball","year":"2016","journal-title":"Curr.
