Association of Lok index with all-cause mortality among critically ill patients suffering from coronary artery disease: a cohort study based on MIMIC database

CONCLUSION: In critically ill CAD patients, a higher Lok index is significantly associated with an elevated ACM risk at 30 days, 90 days, or 365 days, indicating that a higher Lok index is independently associated with both short- and long-term ACM risks. Nevertheless, given the modest per-unit effect size and the retrospective design, the Lok index should not be used in isolation to guide individual treatment decisions.
