Pulmonary Artery Involvement in Patients with Takayasu Arteritis
Bibliographic record
Abstract
OBJECTIVE: This study was performed to explore the clinical manifestations and longterm prognosis in patients with Takayasu arteritis (TA) with pulmonary artery involvement (PAI). METHODS: The medical records of 194 patients with TA who underwent traditional catheter angiography or computed tomography of pulmonary artery from 2009 to 2016 were retrospectively reviewed. The clinical manifestations, angiographic features, and mortality of 128 patients with TA with PAI were further analyzed. RESULTS: Patients with TA with PAI had a higher risk of pulmonary hypertension (PH) than patients with TA alone (61.7% vs 7.6%, p < 0.001). Patients with PAI and PH more frequently developed dyspnea, hemoptysis, and lower limbs edema (all p < 0.05) than those without PH. Patients with PH also had a higher incidence of bilateral PAI (84.8% vs 34.7%, p < 0.001) and a higher pulmonary artery obstruction index [23 (interquartile range 20-27) vs 10 (6-15), p < 0.001]. Left heart disease was presented in 39 (30.5%) patients with TA with PAI. During the median followup of 38 (21-58) months, 19 and 2 deaths occurred among patients with and without PH, respectively. Among patients with PAI, the mortality rate was 7 times higher in patients with than without PH (p = 0.009). Independent predictors of mortality were the disease duration (p = 0.047), New York Heart Association class III/IV (p = 0.019), right ventricular systolic dysfunction (p = 0.019), and respiratory failure (p = 0.007). CONCLUSION: Patients with TA with PAI have a higher risk of developing PH than patients with TA alone. The presence of PH in patients with PAI increases the risk of early mortality.

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.
