Machine learning insights on stress hyperglycemia ratio and mortality in congestive heart failure patients with cerebrovascular disease: an analysis of the MIMIC-IV database
The stress hyperglycemia ratio (SHR), calculated as Admission Blood Glucose (aBG) / (28.7 × glycated hemoglobin A1c (HbA1c) %) − 46.7, integrates acute and chronic glycemic status and predicts adverse cardiovascular events, yet its prognostic value remains unclear among CHF patients complicated with cerebrovascul...
