Persistent Impairment of Coronary Microvascular Dysfunction After Percutaneous Coronary Intervention in an Ice Swimming Champion
Bibliographic record
Abstract
Coronary microvascular dysfunction (CMD) is a recognized cause of persistent angina post-percutaneous coronary intervention (PCI), especially in patients without epicardial coronary stenosis. We report a case of a 58-year-old top-level sportsman and world champion ice swimmer with persistent dyspnea despite successful PCI for a mid-left anterior descending artery lesion. Follow-up angiography with optical coherence tomography showed no in-stent restenosis with good stent apposition. Angiography-derived microcirculatory resistance (AMR, Pulse Medical) and cardiac magnetic resonance imaging revealed CMD as the underlying etiology. This case demonstrates the utility and feasibility of AMR in identifying CMD post-PCI and supports its use in the diagnostic workup.

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.
