The prevalence of migraine and Raynaud's phenomenon in Japanese patients with vasospastic angina (group I) were compared with those in 2 control groups: one with effort angina (group II) and the other group without known ischemic heart disease (group III). There were no significant differences among the 3 groups with respect to age and sex. The prevalence of migraine in group I was 23 of 100, as compared with 4 of 100 in group II (p<0.01) and 11 of 100 in group III (p<0.05). The prevalence of Raynaud's phenomenon in group I was 9 of 100, as compared with 3 of 100 in group II and 4 of 100 in group III. Thus, in Japan, the prevalence of migraine in patients with vasospastic angina was higher than those in the 2 control groups, whereas the prevalence of Raynaud's phenomenon did not differ significantly among the 3 groups. The prevalence of Raynaud's phenomenon in Japanese patients with vasospastic angina was different from that reported from North America, although the prevalence of migraine was the same. This may be partially explained by racial differences.
