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.
