[The possibilities of ultrasound testing in diagnostics of sarcopenia in older patients with chronic heart failure.].

The article presents the results of a study of the possibility of ultrasound testing of sarcopenia in older people suffering from chronic heart failure. All patients (63 persons, mean age 77,2±7,7 years) underwent dual-energy X-ray absorptiometry. Sarcopenia was diagnosed in 31 patients (FNIH sarcopenia project, 2014). The area of the shoulder muscles (m. Biceps brachii), thigh (m. Rectus femoris) and 3 muscles of the forearm (m. brachioradialis, m. extensor carpi radialis longus, m. extensor carpi radialis brevis) was estimated. By performing multiple linear regression analysis, 2 ultrasound models of sarcopenia diagnosis with diagnostic accuracy of 92% and 93,6% are proposed. Models are based on the sum of limb muscle areas adjusted for gender, height and body weight.
