Abstract
INTRODUCTION: The V-GOOD study evaluated the effectiveness of trimetazidine modified-release (MR) 80 mg once daily (OD) in patients with chronic coronary syndrome (CCS) who remained symptomatic despite antianginal therapies in routine clinical practice. METHODS: This prospective, observational study involved 1026 adult outpatients with symptomatic CCS from 70 sites in Brazil who were prescribed trimetazidine MR 80 mg OD plus background antianginal treatment. Data on number of angina attacks, short-acting nitrate consumption, prevalence of angina-free patients, severity of angina, patient-reported daily physical activity impairment, treatment adherence, tolerability, and cardiologist and patient satisfaction were collected at baseline (V1), then at 1 month (V2) and 3 months (V3). RESULTS: Following the addition of trimetazidine MR 80 mg OD, the mean ± standard deviation number of angina attacks per week decreased from 3.1 ± 2.8 at V1 to 1.0 ± 2.1 at V2, and 0.7 ± 1.7 at V3, with concurrent reductions in short-acting nitrate consumption, patient-reported daily physical activity impairment and the proportion of patients with limiting angina (Canadian Cardiovascular Society class III or IV), and increases in the proportion of angina-free patients (all p < 0.001 vs. V1). Most cardiologists rated trimetazidine MR 80 mg OD as satisfactory/very satisfactory (90.7% for effectiveness and 94.8% for tolerability); most patients rated the treatment schedule as convenient/very convenient (97.2%) and satisfactory/very satisfactory (97.1%). Treatment was well tolerated. CONCLUSIONS: These data support the symptomatic benefits and good tolerability associated with adding trimetazidine MR 80 mg OD to other antianginal therapies in patients with persistent symptoms.

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
