Abstract
Cervical angina is a form of non-cardiac chest pain that originates in the cervical spine or cervical cord; it is an under-recognized and easily underdiagnosed condition. Patients with cervical angina often report delayed diagnosis. Here, we report the case of a 62-year-old woman with a history of cervical spondylosis and undiagnosed recurrent chest pain who presented with numbness in the left upper arm and was diagnosed with cervical angina. Although most cases of cervical angina involve uncommon self-limited diseases that improve with conservative treatment, timely diagnosis can reduce patient anxiety and unnecessary office visits and tests. The critical aspect of chest pain evaluation is to rule out fatal disease. Once fatal disease is ruled out, cervical angina should be considered in differential diagnosis if there is a history of cervical spine disease, if the pain radiates to the arm, if it is elicited by cervical spine range of motion or upper extremity movement, or if the chest pain lasts less than a few seconds.

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.

Abstract
STUDY DESIGN This study employed a retrospective study design. OBJECTIVE This retrospective cohort study aimed to compare the outcomes of anterior cervical discectomy and fusion (ACDF), and those of conservative treatment for patients with cervical angina. SUMMARY OF BACKGROUND DATA Cervical angina is typically characterized by intolerable and paroxysmal angina-like precordial pain, which is caused by cervical disk degeneration in patients without definitive cardiovascular abnormalities. Diagnosis is either delayed or neglected because of its various clinical manifestations. Whether conservative or surgical treatment is appropriate remains controversial because of the lack of comparative studies. MATERIALS AND METHODS From 2009 to 2016, 163 patients with cervical angina with advanced chest pain, tightness, or palpitation were retrospectively studied. Twenty-three patients underwent ACDF, and the other 140 patients were treated nonsurgically by medication, physical therapy, collar immobilization, or stellate ganglion block. Japanese Orthopedic Association (JOA) score and 20-point autonomic nervous system (ANS) score were assessed pretreatment and posttreatment. Patients' satisfaction was assessed using the Odom criteria. RESULTS The average age of the patients was 50 years, and most of them were females. The average follow-up was 25.5 months. The pretreatment JOA and 20-point ANS scores in the conservative and ACDF groups were 13.3 versus 11.7 (P=0.110) and 13.0 versus 13.3 (P=0.928), respectively. Generalized estimating equation analysis showed that posttreatment JOA and ANS scores at each observation interval improved significantly in the ACDF group (P<0.001). Angina-like symptoms also improved significantly in the ACDF group (P<0.001). During an average 2-year follow-up, good or excellent results were obtained in 78.2% of surgical patients and 35% of nonsurgical patients. CONCLUSIONS Compared with conservative therapy, surgical treatment with ACDF for cervical angina provided better and more consistent relief from angina-like symptoms and overall sympathetic symptoms. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVE Cervical chest pain (CCP), as 1 atypical symptom associated with cervical spondylosis, often overlaps with other chest-related diseases. CCP obviously relieved after ultrasound-guided cervical nerve root block near a herniated disc should be considered as a potential pathologic source. The purpose of this study is to investigate whether coblation discoplasty can alleviate CCP after positive ultrasound-guided nerve root block. METHODS From August 2016 to September 2019, 21 patients with high suspicion of CCP experienced over 50% pain relieve after ultrasound-guided diagnostic nerve root block. Through 12 months of follow-up, the primary efficacy was assessed with visual analogue scale (VAS) of CCP, and secondary outcomes included: neck pain VAS, neck disability index (NDI), the proportion of significant CCP relief, the rating of CCP alleviation, the patient satisfaction index (PSI), and analgesic consumption. Adverse events were recorded to evaluate safety. RESULTS Following postoperative 12 months, a time-course analysis confirmed a robust decline in VAS of CCP (P < 0.0001), and a similar recovery trend was shown in VAS of neck pain and NDI (P < 0.0001). After treatment, the number of patients taking analgesics decreased (P < 0.0001), and around 60% of patients reported notable relief and satisfaction with treatment. No serious complications were observed. CONCLUSIONS After positive ultrasound-guided nerve root block, coblation discoplasty can provide up to 12 months of relief for intractable CCP.

Abstract
OBJECTIVE Cervical angina, or pseudoangina pectoris, is a noncardiac syndrome of chest pain that often mimics angina pectoris but is a disease of the spine. Diagnosis of cervical angina can be difficult and is often overlooked, although once identified, it can be successfully managed through conservative therapies and/or a variety of surgical interventions. Ultimately, cervical angina is an important component of the list of differential diagnoses in noncardiac chest pain. In the present study, the authors report the first comprehensive systematic review of the range of cervical and thoracic pathologies associated with cervical angina, as well as the different treatment methods used to manage this condition. METHODS A systematic review was performed according to PRISMA guidelines and using PubMed, Web of Science, and Cochrane databases from database inception to April 29, 2020, to identify studies describing spinal pathologies related to cervical angina. The following Boolean search was performed: ("cervical" OR "thoracic") AND ("angina" OR "chest pain") AND ("herniation" OR "OPLL"). Variables extracted included patient demographics, cervical angina pain location, pathology and duration of symptoms, treatment and/or management method, and posttreatment pain relief. RESULTS Upon careful screening, 22 articles published between 1976 and 2020 met the study's inclusion/exclusion criteria, including 5 case series, 12 case reports, and 5 retrospective cohort studies. These studies featured a total of 1100 patients, of which 95 met inclusion criteria (mean patient age 51.7 years, age range 24-86 years; 53.6% male). Collectively, symptom durations ranged from 1.5 days to 90 months. Cervical herniation (72.6%) accounted for the majority of cervical angina cases, and surgical interventions (84.4%) predominated over physical therapy (13.0%) and medical management strategies (9.1%). Every patient assessed at follow-up reported relief from symptoms related to cervical angina. CONCLUSIONS Cervical angina is a noncardiac syndrome of chest pain associated with a broad range of cervical and thoracic spinal pathologies, the most common of which is cervical disc herniation. Although difficult to diagnose, it can be successfully treated when identified through first-line conservative management or surgical interventions in refractory cases.

Abstract
Cervical angina is an often-overlooked etiology of noncardiac chest pain that may mimic true angina pectoris but is due to cervical spine disease. Diagnosis can be difficult, and treatment ranges from conservative therapy to surgical management. However, of patient’s refractory to conservative therapy, approximately ninety percent experience postoperative relief of angina symptoms. Here, we present a case report on cervical angina and performed a systematic review of the literature. A 34-year-old male with prior surgery for thoracic outlet syndrome presented with persistent anterior neck and chest pain as well as posterior left scapular and upper lateral arm pain. The pain was refractory to 12 months of conservative therapy. Cardiac workup was negative and cervical spine imaging revealed a C6–7 herniation with neuroforaminal stenosis. A systematic literature search was conducted in PubMed, Web of Science, and Cochrane databases from database inception to April 2020. Studies reporting cervical level, average symptom duration, location of pain, and postoperative pain improvement were included. The patient's atypical symptoms were completely resolved after C6–7 anterior cervical discectomy and arthroplasty. To our knowledge, this is the first study which reports on the use of arthroplasty in the treatment of cervical angina. The systematic review included 11 articles from 1989–2020 consisting of 1,186 total patients and 109 patients (age range, 36–84 years; 60.7% male) meeting inclusion criteria. Symptom duration range was 2 days to 90 months, with the most common location of pain being localized to the anterior chest wall (66.7% of patients). All patients (100%) had postoperative resolution of their pain symptoms. The most common herniation level was C6–7 (87.3% of patients). We conclude that a broad and multidisciplinary approach is necessary for the diagnosis and management of noncardiac chest pain. When cervical disease is identified as the underlying cause for the angina-like pain, conservative therapy should be sought. Refractory cases should be treated surgically depending on the cervical pathology.

Abstract
Cervical angina has been defined as chest pain that resembles true cardiac angina but originates from the disorders of the cervical spine. Thus, physicians and spine surgeons alike should raise awareness of this unusual condition for diagnosis and treatment. Particularly when neurologic signs and symptoms are present, there should be a strong suspicion for cervical angina in any patient with inadequately explained noncardiac chest pain. Cervical angina can be diagnosed according to negative cardiac workups, positive neurologic examination, and cervical radiographic findings (herniated disk, spinal cord compression, or foraminal encroachment). However, the mechanisms of pain production in cervical angina remain unclear. Previous studies attributed the pain to cervical nerve root compression, cervical sympathetic afferent fibers, referred pain, or lesions of the posterior horn of the spinal cord. Conservative treatments, which include neck collar fixation, head traction, and nonsteroidal anti-inflammatory drugs, have been determined to be successful in most patients with cervical angina. But when conservative treatment fails, anterior cervical surgery with complete decompression of the spinal cord and/or nerve root has been identified to effectively relieve cervical angina symptoms.

Abstract
Objective Cervical angina is an underrecognized type of noncardiac chest pain and its mechanism of pain remains obscure. The objective of the current study was to investigate the clinical outcomes of different surgical strategies for patients with cervical angina and to analyze the potential pathogenesis of Luschka's joint osteophyte. Methods From February 2013 to March 2018, a prospective study on cervical angina was performed in our hospital. All patients who were diagnosed with both noncardiac chest pain and cervical pathology were identified. During admission, they consulted with a cardiologist and underwent strict cardiac workups to exclude true angina pectoris. The included 41 patients were randomly divided into two groups according to different surgical strategies of whether or not to remove Luschka's joint osteophyte during anterior cervical decompression surgery: the osteophyte resection (OR group) and the nonresection (NR group). Results The OR group consisted of 21 patients (8 men and 13 women) with a mean age of 54.7 years (range, 41–65 years). The NR group was composed of 20 patients (9 men and 11 women) with an average age of 56.3 years (range, 43–68 years). Before surgery, the mean duration of symptoms was 6.1 months (range, 4–20 months). The Luschka's joint osteophytes were located at C6–C7 (19 cases, 46.3%), C5–C6 (17 cases, 41.5%), and C4–C5 (4 cases, 12.2%). Their average area was 34.85 mm2 and the average length were 5.09 mm. No statistically significant differences in demographic characteristics were detected between the two groups (P > 0.05). After operation, there were significant improvements in the Japanese Orthopedic Association score and the Neck Disability Index score in both groups (P < 0.05). However, the visual analogue scale score for chest pain in the OR group was statistically lower than that in the NR group (1.4 ± 1.0 vs 2.1 ± 1.6, P < 0.05). In the OR group, the results of cervical spine surgery were excellent in 18 patients (85.7%), and fair in 3 patients (14.3%). In the NR group, there were 10 patients (50.0%) with excellent results, 9 patients with fair results (45.0%), and 1 patient with poor results (5.0%). Notably, there were statistically significant differences between the two groups (χ2 = 6.265, P = 0.044). The average follow‐up was 31 months (24–52 months). Conclusion Anterior cervical decompression surgery with resection of Luschka's joint osteophyte can effectively reduce cervical angina symptom and improve the patient's quality of life. In addition to nerve root compression, Luschka's joint osteophyte may be another pathogenic factor in cervical angina.

Abstract
Cervical angina has been widely reported as a cause of chest pain but remains underrecognized. This series demonstrates the varied clinical presentation of patients with cervical angina, the delay in diagnosis, and the extensive cardiac examinations patients with this condition typically undergo prior to a definitive diagnosis. Recognition of this condition in patients with acute chest pain requires a high index of suspicion and an awareness of the common presenting features and clinical findings of cervical angina.

Abstract
Object
The aims of this study were to review the clinicoradiological findings in patients who underwent decompressive surgery for proximal and distal types of muscle atrophy caused by cervical spondylosis and to discuss the outcome and techniques of surgical intervention.
Methods
Fifty-one patients (43 men and 8 women) with proximal (37, with arm drop) and distal muscle atrophy (14, with wrist drop) underwent cervical decompression (39 anterior decompressions and 12 open-door C3–7 laminoplasties with microsurgical foraminotomy) for muscle weakness in the upper extremities. The clinical course, type of spinal cord compression, abnormal signal intensity on high-resolution MR imaging, and postdecompression improvement in muscle power were reviewed at a mean follow-up of 2.6 years (range 0.8–9.4 years).
Results
The most commonly affected vertebrae were C4–5 and C5–6, and C5–6 and C6–7 in patients with proximal or distal muscle atrophy, respectively; the respective numbers of affected vertebrae were 1.5 and 2.2. Transaxial MR imaging showed medial compression of the spinal cord in 20 patients (in 12 with proximal and 8 with distal muscle atrophy), paramedial compression in 22 (17 and 5 patients, respectively), and foraminal compression in 9 (8 and 1 patient, respectively). Increased signal intensity on MR imaging was observed in 85.0, 22.7, and 11.1% of cases of medial, paramedial, and foraminal compression, respectively. Increased signal intensity at the affected muscle segment level was observed in 52.9, 40.0, and 0% of cases, respectively. Sixty-two percent of patients with proximal muscle atrophy gained 1 or more grades of muscle power on manual muscle testing (MMT), whereas 64.3% with distal muscle atrophy failed to gain even 1 grade of improvement. The recovery of muscle power correlated with disease duration and the percent voltage of Erb point or wrist-stimulated muscle evoked potentials but not with preoperative MMT, longitudinal range of spinal cord compression, signal change on T2-weighted MR imaging, or surgical procedure.
Conclusions
Surgical outcome in patients with distal muscle atrophy was inferior to that in patients with proximal atrophy. The distal type was characterized by a long preoperative period, a greater number of cervical spine misalignments, a narrow spinal canal, and increased signal intensity on T2-weighted MR imaging. It is essential to perform a careful neurological evaluation, including sensory examination of the lower limbs, as well as neuroradiological and neurophysiological assessments to avoid confusion with motor neuron disease and to detect the coexistence of amyotrophic lateral sclerosis, especially when surgical treatment of cervical spondylosis is planned. The results of careful physical examination, MR imaging studies, and electromyography studies should be comprehensively evaluated to ascertain the pathophysiology of the muscle atrophy. It is very important to distinguish the pathophysiology caused by nerve root impingements from anterior horn dysfunction when making decisions about treatment strategy. Surgical treatment—with or without foraminotomy—for amyotrophy in cervical spondylosis requires urgent action with regard to human neuroanatomy and neural innervation of the paralyzed muscles.
