Endothelial Dysfunction Post-COVID Index (Biomarker Composite) Calculator
Endothelial Dysfunction Post-COVID Index (Explanation and Clinical Context) This calculator combines validated indices of endothelial stress and an exploratory composite to contextualize post-COVID vascular dysfunction. EASIX = LDH × Creatinine / Platelets — initially validated in hematologic and COVID-19 populations. Higher EASIX correlates with worse endothelial activation and outcomes. Age-adjusted EASIX (aEASIX-C
