This study presents the effects of AF on sarcopenia indices, including ultrasonographic muscle architecture.\nMaterials and methods:  In this study conducted in neurology units, 72 subjects with AF (mean age: 71 \u00b1 11years, 49% female) were compared with 538 without AF (mean age:66\u00b112years; 53% female) in terms of sarcopenia indices [anthropometry; Short Physical Performance Battery (SPPB); hand grip strength (HGS); bioimpedance analysis (BIA) indices; skeletal muscle mass index (SMMI) normalized to weight, height and body mass index (BMI); and phase angle (PhA)]; muscle ultrasonography [thickness, cross-section area (CSA), fiber length (fL) and pennation angle (PeA) of rectus femoris (RF), biceps brachii (BB), vastus lateralis (VL), vastus intermedius (VIM) and gastrocnemius medialis (GCM)]; possible causes of sarcopenia such as malnutrition; and consequences of sarcopenia [fall, fatigue, SarQol] along with sarcopenia screening (SARC-F). Possible associations were tested in multiple exploratory linear models, and partial r(pr) and p were reported.\nResults: Participants with AF exhibited significantly higher SARC-F and SarQol scores. In multivariable models adjusted for age, sex, height, and body weight, AF was independently linked to lower mean and maximum HGS (pr = \u20130.137, p = 0.014; pr = \u20130.130, p = 0.02), reduced PhA (pr = \u20130.193, p &lt; 0.001), decreased RF thickness (pr = \u20130.120; p = 0.004), and diminished RF+VIM thickness (pr = \u20130.098; p = 0.019). Additional muscle ultrasound parameters, including BB-CSA, RF-CSA, BB-brachialis thickness, VL fL, and PeA and BIA indices, including SMMI(height), SMMI(weight), and SMMI(BMI), tended to be lower in AF.\nConclusion: AF is linked to impaired muscle health and reduced quality of life. Management should include thigh muscle ultrasound and strategies to prevent malnutrition.<\/jats:p>","DOI":"10.55730\/1300-0144.6136","type":"journal-article","created":{"date-parts":[[2026,2,15]],"date-time":"2026-02-15T02:35:56Z","timestamp":1771122956000},"page":"38-47","source":"Crossref","is-referenced-by-count":0,"title":["Sarcopenia in atrial fibrillation: a\u00a0prospective study"],"prefix":"10.55730","volume":"56","author":[{"given":"MEHMET AK\u0130F","family":"TOP\u00c7UO\u011eLU","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"EZG\u0130","family":"YILMAZ","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D\u0130N\u00c7 DO\u011eAN","family":"\u00d6GE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"AL\u0130 NA\u0130M","family":"CEREN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"RIDVAN MUHAMMED","family":"ADIN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ETHEM MURAT","family":"ARSAVA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34691","published-online":{"date-parts":[[2026,2,12]]},"container-title":["Turkish Journal of Medical Sciences"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,10,22]],"date-time":"2026-10-22T14:44:23Z","timestamp":1792680263000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.tubitak.gov.tr\/medical\/vol56\/iss1\/7"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,2,12]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,2,12]]}},"URL":"https:\/\/doi.org\/10.55730\/1300-0144.6136","relation":{},"ISSN":["1300-0144"],"issn-type":[{"value":"1300-0144","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,2,12]]}}}
