Abstract

fetched live from OpenAlex

Coronaryheart disease (CHD) remains one of the main causes of morbidity, early disability and mortality in the adultpopulation, despite significant achievements in the diagnosis and correction of coronary blood flow disorders. An undoubtedachievement at the present stage is the improvement of conservative and X-ray endovascular methods of treatment, but ithas led to an increase in the number of patients with diffuse coronary disorders. We have developed a method of combinedtreatmentof coronary heart disease through direct myocardial revascularization (CABG) in combination with the programYurLeonIII, which allows to improve the results in this group of patients. Aim. To compare the immediate and end resultsof combined surgery (CABG + YurLeon III) with isolated direct myocardial revascularization. Materialand methods.Thestudyincluded 730 patients diagnosed with coronary heart disease, exertional angina pectoris (stages III, IV), who underwentsurgicalrevascularizationof the myocardium in Pirogov National Medical and Surgical Center, Russian Federation. Therewere445 men (60.96%) and 285 (39.04%) women, aged 50 to 73. 580 patients underwent coronary bypass surgery (CABG).150 patients underwent coronary bypass surgery supplemented with indirect revascularization of YurLeon III (CABG +YurLeonIII). Patients underwent gated-SPECT, echocardiography, computer tomography, and quality of life evaluation with the use of SF-36 questionnaire. Results. At the intraoperative stage in the early postoperative period, there were no significantdifferencesin complication rates between t two groups (p > 0.05). 1 year after surgery, statistically significant differences inEF were noted: 55.10 ± 5.98% (after CABG + YurLeon III), 50.07 ± 6.54% (after CABG)(p < 0.05); perfusion defect:18.56 ±9.56%(after CABG) and 8.38 ± 5.79% (after CABG + YurLeon III) (p < 0.05); quality of life: increased in PF, BP, andRE indicators — by 39, 64, and 30 points (after CABG + YurLeon III); by 30, 29, and 26 points (after CABG) (p < 0.05). Conclusion.Coronarybypass surgery, supplemented with YurLeon III, is an effective and safe method of surgical treatment ofpatients with coronary heart disease, especially with diffuse disorders of the coronary arteries. It allows to additionally supplymyocardiumwith the blood.

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.
