Abstract: Critical limb threatening ischemia (CLTI) is associated with a one-year mortality rate of up to 25% making prompt diagnosis essentially. This study aims to investigate if cardiac biomarkers may serve as an effective tool for risk stratification in patients with lower extremity artery disease (LEAD). For this cross-sectional retrospective analysis, 21712 patients with LEAD were screened for eligibility from 2004 to 2020. Out of these patients, 367 were included and subdivided into those with CLTI and those without CLTI. Cardiac biomarkers, including N-terminal prohormone of brain natriuretic peptide (NT-proBNP), troponin, NT-proBNP/troponin ratio, creatin kinase myocardial band (CK-MB) and myoglobin, were retrospectively analyzed. Fifty-nine patients had CLTI (16.1%) with higher rates of NT-proBNP, NT-proBNP/troponin ratio, CK-MB and myoglobin (all p
