An Examination on the Risk Factors of Cerebrovascular Lesions of the Hypertensives in Tohoku Area

Abstract

The factor of the cerebrovascular death was studied from the findings of blood pressures, ocular fundi, electrocardiograms and of proteinuria, of a four year follow-up observation on 2679 hypertensive persons of farm and fishing villages in miyagi prefecture. The results follow: 1) Mortality from cerebrovascular disease was higher at the group with the items of severe ocular findings, of systolic blood pressure 180 mmHg and over, of abnormal ST. T waves in ECG and of proteinuria, compared with the group with less severe findings. 2) The risk becomes much greater when those items of high blood pressure, severer ocular findings than K.W.IIa, ECG findings of abnormal ST.T and of proteinuria accumulate each other. 3) Findings of proteinuria seems to be one of the important risk factors. 4) The risk of a group with the items of systolic pressure 180 mmHg and over, abnormal ST.T waves and proteinuria, was 18.3%. This risk seemed to show no significant difference from that of 12.4% at a group with the items of systolic pressure 180 mmHg and over, abnormal ST.T waves and severer ocular findings than K.W.IIa.
