Giovanni Merlino: Why Does Stress Hyperglycemia Worsen Stroke Outcomes?
Giovanni Merlino, Head of the SOSD Stroke Unit at the University of Udine, shared on LinkedIn about a recent article he and his colleagues co-authored, published in JAHA, adding:
“Stress hyperglycemia worsens outcome in minor stroke. But through which mechanism?
In our new study in the JAHA — Journal of the American Heart Association, we used a causal mediation framework on 1316 patients (5 centers, Italy and the UK) and found that hemorrhagic transformation mediates ~15% of that effect on 3-month functional outcome.
The signal was strongest in younger, non-diabetic patients with elevated CRP, a possible target for future interventional trials.
A special congratulations to Francesco Bax, who led this work.
The causal mediation analysis at the core of this study is entirely his, and the result speaks for itself.”
