Pathologic Findings of Coronary Stents: A Comparison of Sudden Coronary Death Versus Non‐cardiac Death
Bibliographic record
Abstract
There are few histologic studies of intracoronary stents found at autopsy. We studied histologic findings of 87 intracoronary stents from 45 autopsy hearts. There were 40 patients with chronically implanted stents and five shorter than 30 days. Of five patients with recent stent placement, the cause of death was related to the stent (in-stent thrombosis) in one case. Of the 40 patients with chronic stents, there were 16 sudden coronary deaths and 24 noncoronary deaths (controls). There were no late stent thromboses in the coronary deaths. In the coronary deaths, 26% of stents showed restenosis versus 11% in controls (p = 0.1). The rate of healed infarcts and cardiomegaly was similar in the coronary and noncoronary groups, and acute thrombi in native arteries were seen only in three hearts in the coronary group. We conclude that the cause of death is rarely impacted by in-stent findings at autopsy, especially in chronically implanted stents.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
