Rationale: Sarcopenia is defined, according to EWGSOP2, as a reduction in functionality (handgrip strength) and muscle mass (appendicular skeletal muscle index or ASMi). Its management in cardiorenal-metabolic units (UCRM) is increasing. The aim of this study is to assess the incidence of sarcopenia in the UCRM and establish its association with demographic, morphofunctional, and ultrasound parameters.

Methods: This is a prospective analytical study of 88 patients from the UCRM of the Virgen de la Victoria Hospital in Málaga, assessed between February 2022 and June 2023. Demographic data (age and sex), handgrip strength, bioimpedance or BIVA (ASMi lower than 7 kg/m² in men and lower than 5.5 kg/m² in women), and femoral rectus ultrasound (Y-axis lower than 0.96 cm and area lower than 3.6 cm as sarcopenia) were collected. The data were analyzed using the Jamovi 2.6.26 program, with the Shapiro-Wilk test for normality. T-Student or Mann-Whitney U tests were used for group comparisons, and Chi-square or Fisher's test for qualitative variables, considering p<0.05 as statistically significant.

Results: Four patient (6.5%) were diagnosed with sarcopenia, including three men and one woman, with a mean age of 81.5 years. Of the 88 patients, 41.3% had a low Y-axis and 62.7% had a low ultrasound area. Of the 43.5% with dynapenia, 32% had a low muscle area (p<0.032), while of the 22.6% of patients with low ASMi, 20.3% had a low muscle area (p<0.011) and low Y-axis (p<0.046).

Conclusion: 6.5% of the patients had sarcopenia, with no association found with the demographic and ultrasound variables studied. However, dynapenia and ASMi, as independent variables, were associated with low muscle area and low Y-axis. Further studies on the prevalence of sarcopenia in cardiorenal patients are needed to develop detection and treatment protocols.
