Features of the course of stable exertional angina against the background of iron deficiency anemia in outpatient practice
Bibliographic record
Abstract
Introduction. Iron-deficiency accompanies many diseases, including cardiovascular pathology, so timely diagnosis and correction of this condition is necessary. Aim. To study the features of the course of stable exertional angina against the background of iron deficiency anemia before and after correction with iron (III) polymaltose hydroxide in patients in primary health care using a computerized patient register. Materials and methods . 1210 patients with stable exertional angina aged 50–85 years (309 men, 901 women) were included. A special computer program was created for data analysis. In 500 out of 1210 patients, IDA was detected (385 women, 115 men). Mild anemia – 410 patients, moderate – 75, severe – 15. The main group – patients with stable exertional angina and Irondeficiency anemia (the first subgroup – patients treated with iron (III) polymaltose hydroxide and the second subgroup – patients who did not receive the drug iron (III) polymaltose hydroxide due to refusal of treatment or contraindications) and the control group – patients with stable exertional angina without Iron-deficiency anemia. All patients received standard therapy recommended for the treatment of stable exertional angina (the main group additionally received iron (III) polymaltose hydroxide). Results. In the first subgroup of the main group, after treatment with iron (III) hydroxide polymaltose, there was a statistically significant increase in hemoglobin levels by 11,7%, hematocrit by 5%, erythrocytes by 4%, serum iron by 112,8%, and an improvement in exercise tolerance by 48,7%, episodes of ST segment depression by 30,2%. In the second subgroup and the control group, there were no significant changes in the above parameters. Conclusion. Iron-deficiency anemia contributes to the severe course of stable exertional angina, which is confirmed by the high frequency of III-IV functional class exertional angina, a decrease in tolerance to exercise stress. Correction of Iron-deficiency anemia reduces the frequency of episodes of transient myocardial ischemia in the main group.

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.
