Abstract
BACKGROUND: Cardiac syndrome X (CSX) is linked with changes in microcirculation, without significant changes in main coronary vessels. According to European Society of Cardiology 2013 stable coronary artery disease (CAD) criteria, CSX was replaced by microvascular angina (MA). The main feature of MA should be regional myocardial ischaemia; however, there are several works on this subject which failed to demonstrate the presence of perfusion defects. AIM: To determine the effect of non-pharmacological procedures (cardiac rehabilitation) in patients diagnosed with MA on changes in left ventricular perfusion as assessed by myocardial single photon emission computed tomography, along with potential related improvements in exercise capacity. METHODS: Toward this goal we screened for the presence of CAD in a group of 528 women, of whom 55 were not only diagnosed with MA but also agreed to participate in our study, which involved myocardial perfusion imaging (MPI) studies, during which exercise tests and cardiac rehabilitation were performed. RESULTS: Comparison of results obtained at the beginning of the study with data obtained after completion of a three month period of cardiac rehabilitation showed improvements in both exercise test parameters (length of test, metabolic equivalents, blood pressure control during extortion) and MPI parameters for the left ventricle (both at rest and stress, global and regional). CONCLUSIONS: Cardiac rehabilitation is a very useful tool of choice in the treatment of patients with MA.

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 it
