The effects of implementation of guideline-directed medical therapy on relief of angina in patients with stable coronary artery disease in Serbia
Bibliographic record
Abstract
Introduction. Adherence to proposed lifestyle changes and prescribed medication in patients with stable coronary artery disease (SCAD) is poor. Objective. We sought to investigate the influence of adjusting guideline proposed medications on relief of angina in a large group of patients with SCAD in Serbia. Methods. The study included a total of 3,490 patients from 15 cardiology clinics with symptoms of stable angina and at least one of the following criteria: abnormal electrocardiogram (ECG), history of myocardial infarction (MI), positive stress test, significant coronary artery disease on coronary angiogram or previous revascularization. All the patients underwent comprehensive evaluation at initial visit and after two months. The relief of angina was study end-point defined as any reduction in Canadian Cardiology Society (CCS) class, number of angina attacks per week and/or number of tablets of short-acting nitrates per week. Results. Most patients were included based on abnormal ECG (48.4%). At Visit 1, the average number of prescribed classes of medications to a single patient increased from 4.16 ? 1.29 to 4.63 ? 1.57 (p < 0.001). At the follow-up, the patients had significantly lower blood pressure (141 ? 19 / 85 ? 11 vs. 130 ? 12 / 80 ? 8 mmHg; p < 0.001) and most of them reported CCS class I (63.3%). The average weekly number of angina attacks was reduced from 2.82 ? 2.50 at Visit 1 to 1.72 0 ? 1.66 at Visit 2, as well as average weekly use of short-acting nitrates to treat these attacks (2.69 ? 2.53 to 1.74 ? 1.47 tablets; p < 0.001 for all). Conclusion. Adjustment of prescribed medications to guideline recommendations in a large Serbian patient population with prevalent risk factors led to significant relief of angina.

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.
