Normal blood pressure is less common than "hypertension" in the elderly, and most hypertension is primary, or essential. Nevertheless, secondary hypertension in the elderly should be considered in patients with suggestive features, as the prevalence of secondary hypertension increases with age. The most common causes of secondary hypertension in the elderly are renal parenchyma diseases, primary aldosteronism, renal vascular stenosis and drug induced. Timely recognition and treatment of secondary hypertension will reduce the morbidity and mortality associated with uncontrolled hypertension.
Key words: hypertension, high blood pressure, elderly, secondary causes.
