Abstract:
Objective:To assess the usefulness of gray-scale ultrasonography and shear wave elastography in assessing the condition of skeletal muscle in people with chronic heart failure(CHF).Methods:In this prospective study, there were 50 CHF patients and another 50 healthy people undergoing physical checkups served as the control group.The rectus femoris and the gastrocnemius medialis of all participants were evaluated by shear wave elastography and gray-scale ultrasonography.Data were collected using quantitative parameters including muscle thickness, cross-sectional area, fascicle length, pinnation angle, gray value and Young's modulus.Results:Compared with the control group, the thickness(7.80±2.01)mm, cross-sectional area(3.27±0.91)cm 2 and gray value(70.07±6.06)of the rectus femoris and the thickness(12.23±2.42)mm, fascicle length(35.90±1.38)mm and pinnation angle(18.07±3.05)degrees of the gastrocnemius medialis in the CHF group were statistically different[(12.90±2.57)mm, (4.94±2.08)cm 2, 60.93±9.77]for the rectus femoris and(15.90±2.62)mm, (37.83±2.83)mm, (20.75±2.59)degrees for the gastrocnemius medialis of the control group, t=7.71, 3.78, 3.94, 4.99, 4.47, 3.06, P<0.01), but there was no significant difference in Young's modulus of the rectus femoris and the gastrocnemius medialis between the two groups( t=1.10, 0.51, P>0.05).In the CHF group, the thickness, cross-sectional area and gray value of the rectus femoris in different New York Heart Association(NYHA)heart failure grades were statistically different( F=56.36, 69.98, 55.96, P<0.01), but no difference was found in the gastrocnemius medialis with the same ultrasound parameters( P>0.05).When participants in the CHF group was divided into subgroups based on left ventricular ejection fraction(LVEF), there was no significant difference between the subgroups in values of the ultrasonic parameters for the rectus femoris and the gastrocnemius( P>0.05). Conclusions:Gray-scale ultrasound may quantitatively evaluate the skeletal muscle of CHF patients to guide early rehabilitation training to improve their prognosis.
