At a short interval, two cold pressor tests (Double Cold Pressor Test named by authors.) were carried out to 123 persons of over 30 years old. The difference between the first and the second blood prssure response, the response of next year, the relationship of the response to examinations for cerebro-cardiovascular diseases, etc. were discussed. The results were as follows.1. In the both cases of systolic and diastolic blood prssure, the difference between the rised blood pressure and the basal blood pressure at the first cold pressor test (ΔSBP1 and ΔDBP1) and the difference at the second test (ΔSBP2 and ΔDBP2) were not significanlty related to each basal blood pressure.2. ΔSBP1 was significantly related to ΔDBP2 and ΔDBP1 was significantly related to ΔDBP2 in persons of over 30 years old.3. ΔSBP1 was significantly related to ΔSBP at cold pressor test of next year in persons of over 30 years old. However, ΔDBP1 was significantly related to ΔDBP at cold pressor test of next year only in persons of 30∼59 years old.4. The correlationship between ΔSBP2-ΔSBP2 and ΔSBP of next year-ΔSBP1 was significant in persons of over 30 years old. However, the correlationship between ΔDBP2-ΔDBP1 and ΔDBP of next year-ΔDBP1 was significant only in persons of over 60 years old.5. Through the first to the second cold pressor test, the persons having the change of the degree of the two res ponses (ΔSBP1 and ΔSBP2) had the relatively significant prevalence of arteriosclerosis of eye ground. In the case of diastolic blood pressure response, such a relationship was not observed.
