Secondary hypertension, issues in diagnosis and treatment

Abstract

Secondary hypertension (SH) often implies a correctable form of nonessential hypertension. Often certain clinical clues prompt a more extensive evaluation of the causes of the hypertension. Renovascular disease, intrinsic renal disease, primary hyperaldosteronism, and obstructive sleep apnea represent the most common causes of SH. This article defines the disorder and details its epidemiology, prevalence, pathophysiology, physical findings, and treatment strategies.
