RESUMEN
Objective:To investigate the relationship between sarcopenia and chronic heart failure(CHF)in the elderly.Methods:In the retrospective study 365 patients aged≥65 years were randomly divided into the CHF group(n=168)and the non-CHF group(n=188). Skeletal muscle mass(ASM) body mass and skeletal muscle mass index(SMI)were measured and compared between the two groups. The correlation between sarcopenia and CHF in the elderly was analyzed.Results:ASM was(15.46±3.02)kg and SMI was(5.12±0.76)kg/m 2in the CHF group which were significantly lower than those in the non-CHF group[(19.87±2.45)kg and(7.23±0.79)kg/m 2 respectively each P<0.01]. The proportion of subjects with sarcopenia in the CHF group was higher than that in the non-CHF group [26.19%(44 cases) vs. 6.38%(12 cases), P<0.01]. Multivariate Logistic regression analysis showed that age( OR=1.87, 95% CI: 1.132 to 2.285 P<0.05) CHF( OR=23.89, 95% CI: 5.394 to 98.842, P<0.01) gender( OR=20.43, 95% CI: 4.294 to 78.324, P<0.01) and body mass index( OR=23.43, 95% CI: 5.328 to 100.786, P<0.01)were risk factors for sarcopenia in elderly patients. Conclusions:CHF is associated with an increased incidence of sarcopenia in elderly patients.
