In a series of 63 patients, 60 with angina pectoris and 3 with cervical spondylosis and "thoracic spondylosis" showing angina like pain detailed assessments were made of the mode of onset of attack, including electrocardiography during attacks, X-ray examination of the thoracic and cervical vertebrae and neurological examinations, along with coronary arteriography in some cases, with the following results: 1. The cases of angina pectoris were classifiable grossly into two groups according to mode of onset of chest pain: Group A: Angina began with pain in the anterior chest (39 cases); Group B: Angina in the anterior chest was preceded by "pain" occurred elsewhere in the chest (21 cases). The cases in group B were further classified under two categories, types BI and BII, the former being characterized by a sudden onset of "pain" in a somatic area or areas other than the anterior chest where there is usually no dysesthesia, followed by development of retrosternal or precordial pain (6 cases), while the latter type of angina began with paroxysmal exacerbation of preexistent dysesthesia in the nape, shoulder and arms and eventuated in pain in the anterior chest (15 cases). There were two subtypes in the type BII angina viz. types BIIa and BIIb. There was no ECG evidence of ischemic changes at exacerbation of the nucha-omo-brachial dysesthesia in type BIIa while significant ischemic ECG changes were evident in association of aggravation of dysesthesia in the type BIIb patients. 2. Concomitant "cervical spondylosis" with radiographic evidence of abnormalities in cervical vertebrae and associated subjective symptoms accounted for 22.9% of group A and for 71.4% of group B. In no case of type BI was there evidence of such complication whilst all the cases of type BII had this complication. 3. The mode of appearance of pain in patients with cervical spondylosis showing angina like pain resembled to that of angina pectoris in type BII but ECG during attack did not reveal any significant ischemic changes. 4. As for interrelation between findings by selective coronary angiography (26 cases of angina pectoris) and complication of "cervical spondylosis", the complication of "cervical spondylosis" was higher in incidence in the group of cases with low-grade coronary arterial changes (degree of occlusion less than 50%) than in the group with greater arterial changes (degree of occlusion over 50%). The findings described suggest the possibility that the mode of manifestation of anginal attack may be modified by the concomitant presence of "cervical spondylosis".
