Guidelines for the management of hypertension have recommended strict control of blood pressure to help prevent cardiovascular disease. The aim of the present study was to evaluate the current status of blood pressure control and trends over the past two decades. Four hundred patients treated for hypertension at Kyushu University Hospital were included in the present study. Blood pressure levels and prescribed antihypertensive drugs were examined in 2011. The average blood pressure was 129/ 74 mmHg, and the number of prescribed antihypertensive drugs was 2.2. Angiotensin II receptor antagonists, angiotensin-converting enzyme inhibitors, calcium channel blockers, diuretics, alpha-blockers, and beta-blockers were prescribed in 66%, 5%, 78%, 21%, 12%, and 27% of the cases, respectively. Systolic blood pressure was significantly higher, and diastolic blood pressure was significantly lower in patients aged 80 years or older compared with the younger patients (<80 and ≥80 years, 128/75 mmHg and 133/68 mmHg, respectively). The number of prescribed antihypertensive drugs was similar between the two groups. Sixty-five patients were continuously treated for 20 years. The average blood pressure of these patients significantly decreased from 142/87 mmHg in 1991 to 128/71 mmHg in 2011, accompanied with an increase in the number of antihypertensive drugs from 1.6 in 1991 to 2.7 in 2011. These findings suggest that the revised guidelines for the management of hypertension may have contributed to increased awareness and better management of blood pressure levels.
