Abstract:
During the past four years authors encountered a total of 25 tourists suffered from cerebral (CI: 14 cases) and acute myocardial infarction (AMI: 11 cases) while staying in Kusatsu Hot Spring. The subjects consisted of 13 males and 12 females, ranging from 49 to 85 years old (mean 68±9.5). Analytical study relating to the time of onset of diseases, bathing, drinking and others was performed in these patients. The results obtained were as follows.
1) Higher incidence was observed from May to October in CI, while from March to April and in September in AMI. A majority of the subjects suffered from CI or AMI within two days after arrival in Kusatsu. Attack occurred during bathing in one subject, within six hours after bathing in one, and from six to 24 hours after bathing in the others, respectively. Furthermore, a hourly distribution of the onset of disease showed the high incidence of CI between 3:00 and 9:00, and of AMI between 21:00 and 0:00.
2) Bathing was done one to four times within 24 hours before onset in all subjects. Meanwhile, drinking was in 56% of the subjects.
3) Out of 21 subjects investigated six cases were under medication with hypotensive drugs.
From the results above described, a role of bathing playing in pathogenetic mechanism in thrombotic diseases such as CI and AMI was briefly discussed.
