NPPB and hydrops fetalis: Sarcopenic HF patients were significantly older (74.5 [68.7–80.2] vs. 68.4 [60.9–74.8] years; p = 0.001), had a lower proportion of women (3.6 vs. 24.3%, p = 0.013), higher N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) levels (3693.2 [1183.3–5000.0] vs. 1066.4 [521.3–2453.6] pg/mL; p < 0.001) and lower left ventricular ejection fraction (LVEF) (31.1 [26.2–47.5] vs. 40.0 [30.0–55.0] %; p = 0.025) compared to non‐sarcopenic HF patients.
