Secondary hypertension

In patients with hypertension and chronic renal parenchymal disease, BP should be controlled to 130/85 mmHg or lower (125/75 mmHg) in patients with proteinuria in excess of 1 g/day. Reducing dietary sodium (< 7 g/day) and protein (< 0.6-0.7 g/kg) helps control high BP and renal function in patients with renal insufficiency. As first antihypertensive drug, ACE inhibitors or long-acting Ca antagonists are recommended. In patients with renovascular hypertension, angioplasty is the first choice increasingly to be accompanied by stenting, and surgical revascularization is the next choice. As antihypertensive drugs, beta blockers, ACE inhibitors, and AII-receptor blockers are recommended. Hypertension accompanied by endocrine disease with adenoma or tumor is almost cured or improved by surgical removal. Spironolactone and Ca antagonists are used in patients with idiopathic aldosteronism (bilateral hyperplasia). Alpha and beta blockers are used in patients with pheochromocytoma during preoperative period.
