Cervical Radiculopathy as a Hidden Cause of Angina: Cervicogenic Angina
Bibliographic record
Abstract
Patients presenting with chest pain to the emergency department constitute a diagnostic challenge as 77% of the patients' symptoms are not cardiac. Diagnostic uncertainty is a pervasive issue in primary care. A 56-year-old man presented with non-traumatic chest pain and chronic neck pain for 2 years, as well as numbness in his right third and fourth fingers for 6 months. It was not associated with palpitation, orthopnea or pedal edema. Except for hyperglycemia, no abnormal findings were found in diagnostic tests. At that time, he was being treated for type 2 diabetes using glucose-lowering drugs in order to lower his blood glucose and lessen his risk of heart disease. The cause of his chest pain remained unknown. Following a second opinion from an orthopedist, the patient was diagnosed with cervical radiculopathy and was treated with analgesics and physical therapy. Because the treatments had only provided temporary pain relief for the previous 6 months, he sought chiropractic care for pain relief. The patient's vital signs were stable and within normal limits during the assessment. A restricted neck movement, a positive Spurling test, and hypoesthesia in the right C7 dermatome were seen. Cervical radiographs revealed degenerative spondylosis with right C5/C6 neuroforaminal stenoses and bilateral C6/C7 neuroforaminal stenoses. A provisional diagnosis of cervical spondylotic radiculopathy associated with cervicogenic angina (CA) was made. Chiropractic procedures, including cervical manipulation, instrumented soft tissue mobilization, and motorized intermittent neck traction, were performed two to three times per week. After 3 months, the patient reported that the chest pain, neck pain, and radicular symptoms had completely resolved. Repeated radiographs taken during the 11th month follow-up revealed a comparable improvement in the increased spacing of the restricted neuroforamina, which could signify a beneficial alteration related to cervical function retrieval. CA is an angina-like chest pain caused by cervical spine disorders. This study adds to our understanding of the biomechanical impact of cervical radiculopathy on chest pain, which has largely been overlooked during diagnostic workups. Once cervical radiculopathy has been identified, CA symptoms can be eased by alleviating the noxious input stemming from the pinched nerve roots.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
