Abstract
This chapter examines the association of anxiety disorders and anxiety symptoms with cardiovascular disease, focussing on hypertension (an independent risk factor for myocardial infarction and stroke) and coronary heart disease. In both cases, epidemiological data linking the cardiovascular disorder with specific anxiety disorders and anxiety symptoms are examined first, and evidence relating to putative mechanisms that may underlie these associations is explored. For hypertension, an association with panic attacks and panic disorder has been reported most consistently, but the literature relating to other forms of anxiety is inconsistent, especially as some studies have reported an association of anxiety with low blood pressure. Recent work which has attempted to elucidate this confusing situation is presented. Mechanisms which may be responsible for the link between hypertension and panic include autonomic nervous system dysfunction (which may be under serotonergic control), respiratory mechanisms, cytokines, platelet dysfunction and behavioural factors. While an association of depression with coronary heart disease has been studied extensively, the association with anxiety disorders has been slower to emerge. Studies contributing to this evidence base are examined, and as for hypertension putative mechanisms are discussed.

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.
