Images will be taken at two sites; the lateral thigh and bicep on the dominant side if able to identify, or else on the right side. On each visit, five images will be taken at each site (the lateral thigh and bicep). Participants will be measured 2-3 days from initiation in study, then 7 days after, and then weekly from the first measurement until time of advanced therapy, discharge, or death. This measurement sequence will then be repeated following advanced therapy up until discharge or death. Each measurement session will last about 20-30 minutes. This will be performed by the PI or members of the study team who have been trained by the research coordinator.",[9],[21],{"name":22,"role":23,"phone":24,"phoneExt":10,"email":25},"Amanda R Vest, MBBS","CONTACT","617-636-8068","avest@tuftsmedicalcenter.org",[27],{"facility":5,"status":28,"city":29,"state":30,"zip":31,"country":32,"countryCode":33,"cosmosGeoPoint":34,"geoPoint":39,"contacts":40},"RECRUITING","Boston","Massachusetts","02111","United States","US",{"type":35,"coordinates":36},"Point",[37,38],-71.05977,42.35843,{"lat":38,"lon":37},[41,45],{"name":42,"role":23,"phone":43,"phoneExt":10,"email":44},"Olivia Lovegreen","617-636-5000","OLovegreen@tuftsmedicalcenter.org",{"name":22,"role":23,"phone":10,"phoneExt":10,"email":10},{"type":47,"investigatorFullName":10,"investigatorTitle":10,"investigatorAffiliation":10,"oldNameTitle":10,"oldOrganization":10},"SPONSOR","100535536","changes-in-skeletal-muscle-thickness-in-patients-with-acute-heart-failure-100535536",false,"NCT06253104","Changes in Skeletal Muscle Thickness in Patients With Acute Heart Failure","Inclusion Criteria:\n\n1.

Advanced therapies such as OHT and VADs in the heart failure (HF) population may promote skeletal muscle mass and subsequent quality of life, but there is a lack of literature assessing muscle mass changes in HF patients before and after advanced therapies using US imaging. Therefore this observational study will provide further insight into the 1) changes in lean body mass during critical illness and 2) the feasibility of using bedside US to assess lean body mass in the inpatient setting.",[63,64,65,66],"Heart Failure","Muscle Atrophy","Skeletal Muscle Atrophy","Cardiogenic Shock","2025-04-18",{"date":69,"type":70},"2025-04-23","ACTUAL",{"date":72,"type":70},"2024-02-19",{"date":74,"type":59},"2026-12-31",{"name":5,"class":6},1]
