Abstract

fetched live from OpenAlex

Stroke-heart syndrome describes the neurocardiogenic mechanisms that lead to the development of poststroke cardiovascular complications. We describe a 25-year-old man with Carvajal syndrome who developed advanced biventricular heart failure 2 months after a large territory ischemic stroke. His condition was managed with inotropic support initially and required biventricular assist devices as a bridge to possible heart transplantation. This case highlights the increased risk of cardiovascular complications after stroke through dysregulation of the brain-heart axis. Poststroke neuron death leads to systemic and local inflammation through noradrenaline, interleukin-1, and other proinflammatory cells. This cumulatively leads to endothelial dysfunction and cardiomyocyte fibrosis/necrosis within the heart.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
