Posttraumatic Stress Disorder and the Risk of Heart Failure Hospitalizations Among Individuals With Coronary Artery Disease
Bibliographic record
Abstract
BACKGROUND: Posttraumatic stress disorder (PTSD) is associated with maladaptive dysregulation of stress response systems, which could lead to an increased risk of heart failure. We investigated whether PTSD was independently associated with first and recurrent heart failure hospitalizations in the setting of coronary artery disease. METHODS: Individuals with stable coronary artery disease and without heart failure at baseline were enrolled in 2 parallel prospective cohort studies in metropolitan Atlanta, GA. Participants underwent a structured clinical interview to assess their lifetime history of PTSD. Current PTSD symptoms were assessed using the PTSD symptom checklist. Participants were followed up for a median time of 4.9 years. The primary end point was first or recurrent hospitalization for heart failure. Secondary end points included cardiovascular death and nonfatal myocardial infarction with and without hospitalization for heart failure. Survival analysis for repeated events was used to assess the association of PTSD with adverse events. RESULTS: We studied 736 individuals with a mean age of 60±10 years; 36% were Black, and 35% were women. In total, 69 (9.4%) patients met the criteria for PTSD. Having a PTSD diagnosis was associated with the primary end point of first or recurrent heart failure hospitalizations, with a hazard ratio of 4.4 (95% CI, 2.6-7.3). The results were minimally attenuated after adjusting for demographic and clinical factors (hazard ratio, 3.7 [95% CI, 2.1-6.3]). Similarly, a 10-point increase in the PTSD symptom checklist score was associated with a 30% (95% CI, 10%-50%) increase in heart failure hospitalizations. PTSD was not associated with an end point of cardiovascular death or nonfatal myocardial infarction, which excluded hospitalizations due to heart failure. CONCLUSIONS: Among patients with coronary artery disease, PTSD is associated with incident and recurrent heart failure hospitalizations. Future research is needed to investigate whether PTSD management can reduce the risk of heart failure.

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.
