title: Pathophysiology of hypertension in the elderly.
abstract: Combined systolic and diastolic arterial hypertension and isolated systolic hypertension in the elderly are proven risk factors for stroke, sudden death, coronary artery disease, and congestive heart failure. Because hemodynamics, vascular and cardiac adaptations, fluid volume, and endocrine functions are distinctly altered in the elderly hypertensive patient compared with a younger patient, antihypertensive treatment should be individualized, and an unsophisticated regimen, such as a stepped-care approach, is too rigid to be as beneficial for elderly hypertensive patients as for young hypertensive patients.
