My patient treated with oral anticoagulants: two faces of patients
Bibliographic record
Abstract
This paper presents two patients with atrial fibrillation. The first patient is a young 46-year-old, working, active male, who has only hypertension and pharmacologically well-controlled hyperthyroidism. He was diagnosed with persistent atrial fibrillation lasting four days (EHRA III, CHA2DS2-VASc 1 point, HAS-BLED 0 point). After excluding embolic material based on the transesophageal echocardiography and implementation of non-vitamin K antagonist oral anticoagulant (NOAC), effective electrical cardioversion was performed. Due to poorly tolerated recurrences of atrial fibrillation (EHRA III) in the clinical observation, the patient has been classified for circumferential pulmonary vein isolation (PVI), which was performed after a routine transesophageal echocardiography. The patient continued anticoagulation with NOAC before and post procedure for 2 months. Another patient is a 78-year-old man, treated chronically, so far only because of hypertension. He was admitted to the cardiology department due to the cardiovascular decompensation and increased symptoms of heart failure for 3 weeks prior to hospitalization. During the hospitalization, the patient was diagnosed with persistent atrial fibrillation (EHRA II, CHA2DS2-VASc 4 points, HAS-BLED 3 points), moderate mitral and tricuspid valve regurgitation, chronic renal failure stage III, microcytic anemia, thrombocytopenia, iron deficiency, benign prostatic hypertrophy and osteoarthritis of the spine. Additional aggravating factors were newly diagnosed cognitive function decline and considerable fragility of the patient (4th degree according to the Canadian Study of Health and Aging Clinical Frailty Scale). After the improvement of the patient status, taking into account the limitations and contraindications to anticoagulation, NOAC was administered. Electrical cardioversion was planned during next hospitalization. 1.

Multidisciplinary approach to the choice of appropriate anticoagulant therapy, depending on the patient’s condition, the planned treatment for restoring sinus rhythm (cardioversion or PVI) with regard to comorbidities, should be a priority in everyday clinical practice.

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.
