Abstract 18268: Angina and Functional Capacity Among Women Presenting With Angina and Non-Obstructive Coronary Disease
Bibliographic record
Abstract
Introduction: Approximately 75% of women that undergo coronary angiography for angina do not have obstructive disease. However, a significant number have persistent angina, which can reduce their functional capacity and performance, impacting patients’ quality of life. There is a need for further studies that accurately compare angina and functional capacity among women angina with non-obstructive coronary disease (ANOCA). Objective: We examined the association between perceived anginal symptoms and functional capacity in patients with ANOCA Methods: A the Women’s Heart Center at the Christ Hospital, all women completed the Duke Activity Status Index (DASI) and Seattle Angina Questionnaire-7 (SAQ7) at the initial visit. DASI score range from 0 to 58.2 and assess functional capacity using self-assessment and VO2 peak formula with higher scores indicating better functional capacity. SAQ7 assesses angina symptoms, physical limitation, and quality of life; the score is from 0-100, where a lower score indicates a higher frequency of angina, increased physical limitation, and poor quality of life. DASI and SAQ7 scores were correlated. Sperman correlation and Mcnemar chi-square were used to compare DASI and SAQ7 score results. Results: Among 225 women with ANOCA, the mean DASI score was 16.73, and the mean SAQ7 score was 43.79. 63.1% reported a low score of SAQ7, and 79.6% reported a low DASI score. SAQ7 and DASI were moderately correlated (Spearman correlation of +0.42). Further analysis with McNemar chi- square showed that women with lower SAQ7 (score 0-49.4) tends to corresponds with low DASI (score 0-24.5) (Specificity 86.6%), compared to women with higher SAQ7 (score 49.5-100) and high DASI (score 24.6-58.2) (Sensitivity 32.5%) (p<0.001). Discussion: Anginal symptoms are correlated with reduced functional capacity among women with ANOCA. Further prospective studies are needed to evaluate the correlation between angina improvement and functional capacity.

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.
