[Clinical characteristic of secondary hypertension in the elderly].

The prevalence of secondary hypertension is higher in the elderly population. Renal hypertension is the most prevalent. The prevalence of renovascular hypertension (RVH) increases with age. Since RVH in the elderly is frequently associated with systemic atherosclerosis, other atherosclerotic disorders including ischemic heart disease need to be evaluated. The prevalence of primary aldosteronism and Cushing's syndrome decreases with age, while that of pheochromocytoma persists in the elderly population. Due to lack of classical symptoms, special attention should be paid to find pheochromocytoma in the elderly.
