Adequate control of blood pressure (BP) is important to slow the progression of chronic renal failure (CRF). The Joint National Committee (JNC) VI recommends BP <130/85 mmHg, or <125/75 mmHg if urinary protein excretion exceeds 1 g/d. Angiotensin converting enzyme inhibitors (ACE-I) are considered as first-line agents. The current study ...
