Abstract

fetched live from OpenAlex

Background Myocardial infarction with no obstructive coronary arteries (MINOCA), and ischemia with no obstructive coronary arteries (INOCA), are female-predominant conditions; clinical trials are lacking to guide medical management for the common underlying vasomotor etiologies. Data on long-term outcomes of (M)INOCA patients following attendance at a women's heart centre (WHC) are lacking. Methods Women diagnosed with MINOCA (n = 51) or INOCA (n = 112) were prospectively followed for 3 years at the Leslie Diamond WHC (LDWHC) in Vancouver. Baseline characteristics, diagnoses, chest-pain type, major adverse cardiac events, hospital encounters, medications, and Seattle Angina Questionnaire (SAQ) responses were compared between the baseline and 3-year timepoints. The χ 2 test was used to compare categorical variables; the Student t test was used for continuous variables. Results MINOCA patients had significantly more nonexertional chest pain and more diagnoses of vasospasm than did INOCA patients, who had more exertional chest pain and more diagnoses of coronary microvascular dysfunction. Following the baseline timepoint, both groups had significant reductions in cardiovascular emergency room visits, with INOCA patients also experiencing fewer cardiovascular hospitalizations. At 3 years, the most commonly prescribed medications were calcium-channel blockers, long-acting nitrates, and beta-blockers, with MINOCA patients having more acetylsalicylic acid use, and INOCA patients having more short-acting nitrate and ranolazine prescriptions. Both groups observed significant improvements in SAQ scores, with greater improvements observed in INOCA patients. Patients with depression or who were prescribed ranolazine at 3 years had worse SAQ scores at baseline. Conclusions The 3-year outcomes of (M)INOCA patients indicate that the LDWHC's comprehensive care model effectively improves diagnostic clarity, reduces the number of hospital encounters, optimizes medication management, and improves self-reported patient well-being.

Not 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.
