Demonstrates that sarcopenia correlates with elevated B-type natriuretic peptide in acute decompensated heart failure, highlighting skeletal muscle loss as an indicator of disease severity.
).Sarcopenia was present in 52.6% of study patients. B-type natriuretic peptide (BNP) levels were significantly higher in ADHF patients with sarcopenia than in those without sarcopenia (1666 versus 429 pg/mL, P < 0.0001). Receiver operator curves were used to compare the predictive accuracy of SMI and FFMI for higher BNP levels. Areas under the curve for SMI and FFMI were 0.743 and 0.717, respectively. Multiple logistic regression analysis showed sarcopenia as a predictor of higher BNP level (OR = 18.4; 95% CI, 1.86-181.27; P = 0.013).Sarcopenia is associated with increased disease severity in ADHF. SMI based on DXA is potentially superior to FFMI in terms of predicting the degree of severity, but FFMI is also associated with ADHF severity.
