    Sarcopenia is prevalent in patients with cardiovascular disease (CVD) and linked to functional decline and adverse outcomes.

  • 2

    The study identified TyG-BMI as the most informative composite biomarker for sarcopenia risk assessment in CVD patients.

  • 3

    A CatBoost machine learning model incorporating TyG-BMI demonstrated strong discriminative ability for sarcopenia across multiple cohorts.

  • 4

    The Cardiovascular Disease–Sarcopenia Risk Score (CVD-SRS) was derived and validated for consistent risk stratification in diverse populations.

  • 5

    Current sarcopenia diagnostic methods are often impractical in routine cardiovascular practice, highlighting the need for simpler tools.
