Valvular heart disease and calcification in CKD: more common than appreciated
Bibliographic record
Abstract
Ischaemic heart disease, sudden cardiac death and arrhythmias, heart failure, stroke and peripheral arterial disease make up >50% of the causes of death in advanced chronic kidney disease (CKD). Calcification of the vascular tree and heart valves is partially related to these complications and has received growing attention in the literature. However, the main focus of research has been on the pathophysiology and consequences of vascular calcification, with less attention being paid to valvular calcification (VC) and its impact on the survival of CKD patients. Although VC has long been seen as an age-related degenerative disorder with minimal functional impact, several studies proved that it carries an increased risk of death and clinical consequences different from those of vascular calcification. In dialysis patients, the annual incidence of aortic valve calcification is nearly 3.3% and the reported prevalence of aortic and mitral VC varies between 25% and 59%. Moreover, calcification of both valves occurs 10-20 years earlier in CKD patients compared with the general population. Therefore, the purpose of this review is to summarize the current knowledge on the pathophysiology and relevance of VC in CKD patients, and to highlight specific clinical consequences and potential therapeutic implications.

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.
