To evaluate the current status of the management of hypertensive patients in Japan, we investigated 907 treated hypertensive patients (486 females and 421 males; mean age, 66.7 years) followed by cardiologists. According to the guidelines for the management of hypertensive patients in Japan in 2000 (JSH-2000), only 41.5% of the subjects achieved the target blood pressure, with a mean systolic blood pressure of 140.0±14.9 mmHg and a mean diastolic blood pressure of 80.0±10.7 mmHg. There were no differences between patients with and without concurrent disease or among age groups (<60, 60-69, 70-79, and 80 years and over) in systolic blood pressure levels achieved. However, the diastolic blood pressure decreased with age, indicating an increase of the pulse pressure. Overall, the prescription rates were: calcium channel blockers (CCBs), 73.0%; angiotensin converting enzyme inhibitors (ACE-inhibitors), 31.3%; angiotensin receptor blockers (ARBs), 18.9%; β-blockers, 16.2%; and diuretics, 10.1%. Although some selection of antihypertensive drugs was based on evidence from previous trials on hypertensive patients with diabetes mellitus, chronic heart failure and renal insufficiency, overall, CCBs were selected in all age groups and in all comorbid conditions. In conclusion, Japanese cardiologists do not appear to consider age and comorbidity when choosing antihypertensive managements. Based on current evidence, the management of hypertension should be individualized, with the blood pressure target level and antihypertensive medications chosen on the basis of age and comorbidity.
