Cardiovascular disease
Muscle ultrasonography and frailty in cardiac surgery
Correlation between muscle ultrasonographic assessment of rectus femoris and Clinical Frailty Scale in elective cardiac surgical patients
The secondary objectives of this study are to: 1. Determine the association between preoperative muscle ultrasonographic assessment on MT, CSA and echogenicity of RF, and physical performance and activity level. 2. Determine the association between preoperative muscle ultrasonographic assessment on MT, CSA and echogenicity of RF, and postoperative outcomes up to 30 days after surgery.

All adult patients scheduled for elective cardiac surgery admitted to the cardiothoracic surgical ward a day before surgery will be asked to participate in the cohort study. They will be enrolled if written informed consent is made. We will recruit 85 consecutive patients undergoing major elective cardiac surgery, including coronary artery bypass graft, valve surgery or aortic intervention.；
登录查看We will exclude patients undergoing emergency cardiac surgery, or patients with known musculoskeletal or neurological disorders that are associated with lower limb muscle atrophy (e.g. poliomyelitis, stroke, peripheral neuropathy); previous major surgery at lower extremity (e.g. hip replacement, metal implants at femur); or conditions that influence or are unsuitable for muscle ultrasonographic assessment, such as localised infection, skin disorders or compromised skin integrity, severe edema over thigh, and cognitive impairment (inability to provide consent).；
