High calcium score in an 83-year-old patient with non-ST elevation acute coronary syndrome and nonobstructive coronary artery disease: a case report
Bibliographic record
Abstract
Currently, multi-slice computed tomography (MSCT) coronary angiography is a leader in the diagnosis of coronary artery disease in patients with non-ST elevation acute coronary syndrome of low or moderate risk. High coronary calcium score (CCS) obtained by MSCT indicate a high probability of obstructive coronary artery disease. In the presented case of an 83-year-old patient with unstable angina, the CCS was 1394, and hemodynamically significant stenoses were detected. However, according to selective coronary angiography, no hemodynamically significant coronary lesions were found. High CCS suggests poor image quality in MSCT coronary angiography. High CCS is detected in most people over 70 years of age. Obviously, in this patient, a high CCS is mainly determined by age. Most studies on CCS did not include patients over 80 years of age. When deciding whether to perform MSCT coronary angiography, it is necessary to take into account the individual characteristics of a particular patient, which may affect the interpretation of results.

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.
