BACKGROUND: Cardiac hypertrophy and failure are major complications of hypertension. OBJECTIVES: The beneficial effect of treatment with antihypertensive drugs on serum levels of brain natriuretic peptide (BNP) was examined in patients with essential hypertension. METHODS: Antihypertensive drugs were administered to 88 hypertensive patients (44 diabetic and 44 nondiabetic) whose systolic blood pressure was greater than 140 mmHg and/or diastolic blood pressure was greater than 90 mmHg. Other antihypertensive drugs were added every two months until the blood pressure fell below 130/85 mmHg. Candesartan, benidipine, bisoprolol or celiprolol, and bunazosin were administered in this order. RESULTS: The mean systolic blood pressure was reduced from 163.7+/-11.6 mmHg to 121.8+/-7.5 mmHg after 12 months in patients with diabetes and from 167.6+/-12.3 mmHg to 122.8+/-7.5 mmHg in patients without diabetes. The mean diastolic blood pressure was also significantly reduced in patients with and without diabetes. Serum BNP levels were reduced from 52.2+/-38.8 pg/mL to 38.8+/-30.9 pg/mL in patients with diabetes and from 47.1+/-34.2 pg/mL to 35.8+/-22.5 pg/mL in patients without diabetes. In patients older than 70 years of age, serum BNP levels were reduced from 56.3+/-39.3 pg/mL to 40.2+/-23.0 pg/mL in those with diabetes and from 54.6+/-32.9 pg/mL to 38.0+/-16.0 pg/mL in those without diabetes. CONCLUSIONS: These results indicate that combination therapy with antihypertensive drugs is usually necessary to reduce blood pressure to below 130/85 mmHg and to improve serum BNP levels. |
