Subclinical Cardiac Microdamage, Motor Severity, and Cognition in Parkinson's Disease
Bibliographic record
Abstract
BACKGROUND: We assessed if cardiac blood markers are associated with motor and cognitive function in patients with Parkinson's disease (PD). METHODS: High-sensitivity troponin I and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were evaluated in 285 PD patients. Furthermore, N-terminal pro-B-type natriuretic peptide levels were analyzed in 570 age, sex and cardiovascular risk factor matched healthy controls. Motor (UPDRS, Hoehn &Yahr) and cognitive function (Montreal Cognitive Assessemtn) were assessed at baseline in all 285 patients and after 1 year in 101 patients. RESULTS: N-terminal pro-B-type natriuretic peptide were significantly increased in 285 PD patients compared with 570 matched healthy controls. In PD patients, increased high-sensitivity troponin I and N-terminal pro-B-type natriuretic peptide levels were associated with worse motor function at baseline and also with motor decline after 1 year. N-terminal pro-B-type natriuretic peptide and high-sensitivity troponin I were inversely associated with cognitive function at baseline only in unadjusted models. CONCLUSIONS: Subclinical cardiac microdamage is associated with motor severity in PD patients. © 2020 The Authors.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
