Description
Nanru Peng, Peizhe Li, and Yimeng Liu test a blood sugar ratio as a death warning in critically ill patients with mitral valve disease. The stress hyperglycemia ratio compares the sugar spike of acute illness against a patient's long-run average. Using an intensive care database, the team sorted 3,506 patients into four bands by that ratio and tracked deaths over twenty-eight days.
Higher bands died more often, and the top quarter carried the greatest risk, above all in patients without diabetes. The risk curve bent into a U, so very low ratios were not safe either. The signal held across sexes and glucose states, running strongest in women and in prediabetes. A gradient-boosted model using the ratio reached strong accuracy for predicting death. The authors propose the ratio as a cheap guide for personal glucose care in the unit.
