Abstract

Objective:

Although hypertension is a common disease in elderly population, special attention needs to be paid since elderly individuals often have multiple diseases and atypical presentations and show marked individual differences in the physiological function. Most guidelines for the management of hypertension emphasize these points and, thus, may contribute to an improvement in the management of elderly hypertension. The present study was designed to investigate changes in blood pressure, the prevalence and treatment rate of hypertension, and the achievement rate of the target blood pressure in the elderly during the last 14 years.

Design and Method:

Among 102,610 participants who visited our hospital for a physical check-up from 2002 to 2015, 27,542 elderly participants (≥65 year-old, male 18,805) were divided into two groups; young-old (65–74 year-old, n = 22,295) and old-old (≥75 year-old, n = 5,247) participants. Changes in blood pressure, the prevalence and treatment rate of hypertension, and the achievement rate of the target blood pressure were investigated. Subjects with blood pressure≥140/90 mmHg or using antihypertensive medication were diagnosed as hypertension, and the target of blood pressure was less than 140/90 mmHg.

Results:

The main results are shown in the table. Over the past 14 years, the prevalence and treatment ratio of hypertension and the achievement rate of the target blood pressure were increased and the blood pressure of the hypertensive elderly under hypertensive treatment was decreased.

Conclusions:

Guidelines for the treatment of hypertension generally have beneficial influence on the management of elderly hypertension. The mean blood pressure in the elderly was markedly reduced during the last 14 years, mainly due to the reduction in blood pressure in the elderly under medication. However, the prevention of hypertension has not been achieved yet.
