The stress hyperglycemia ratio (SHR) is a recently introduced biomarker significantly associated with poor outcome in AIS. Objectives: This study aimed to investigate in what extent frailty, measured by MPI, and SHR affects the 3-months outcome of AIS patients > 65 years-old. Methods: Consecutive patients with AIS >65 years-old who underwent intravenous thrombolysis (IVT) from 2015 to 2019 were enrolled in a German and an Italian Stroke Unit. The SHR was calculated by dividing the fasting plasma glucose at admission with glycated haemoglobin. Demographics and clinical premorbid data, stroke-related variables, including baseline and post-treatment NIHSS score were included in a logistic regression model. The 3-months functional outcome was evaluated by using modified Rankin scale (mRS); good outcome was defined as mRS 0-2, poor as mRS ≥ 3. Results: 155 AIS patients were enrolled in the study. Median MPI was 0.19 [0.13-0.31]; 118 (76.1%) patients were classified as “robust” and 37 (23.9%) as “frail”. In regression analysis, age, NIHSS and MPI demonstrated as the most significant predictor of 3-months good outcome in the whole cohort. In robust patients, SHR values were significantly associated with the outcome. Conclusions: MPI is associated with the 3-months outcome in our cohort, in particular with good outcome. Conversely, SHR seems to be associated with a 3-months poor outcome in “robust” patients but not in frail patients.
