Does prompt treatment of hypertension after blood pressure check-ups reduce morbidity of cerebrovascular diseases?

In Japan, more than 20 million people utilize blood pressure check-up services in their work places or communities every year. To examine the relationship between prompt treatment of hypertension after these blood pressure check-ups and the severity, age at onset, and type of cerebrovascular diseases in these patients, a study was performed with the cooperation of all 174 independent physicians, 17 hospitals, and 4 welfare homes in the city of N.. All patients aged 50 years or more who visited a physician during the study period in this city were included in the study (n=978). Information on hypertensive control before the onset of cerebrovascular diseases was obtained from 668 patients. The results suggests that for those who had received prompt treatment after early detection of hypertension, the disease was less severe and the onset of the disease was delayed. Among our subjects, 47% of the patients claimed to have received prompt treatment after detection of hypertension. As N. is an ordinary Japanese city in terms of the promotion of health check-up programs, this percentage suggests that blood pressure check-up programs for the early detection of hypertension throughout Japan may have contributed to an overall reduction in severity for almost half of the patients with cerebrovascular diseases.
