Secondary hypertension.

Endocrinologic causes of secondary hypertension are extremely rare in the elderly population. The most common correctable cause of secondary hypertension in elderly persons is renovascular hypertension (RVHT). With aggressive investigation and intervention, RVHT can be corrected with low mortality and morbidity at referral institutions. Angioplasty is less effective in elderly persons with RVHT. Results of revascularization are good in terms of improvement of blood pressure control and preservation of renal function in the elderly population.
