To achieve the objectives of the baseline evaluation of older persons with hypertension, age-related changes that affect blood pressure measurement, assessment of target-organ effects, cardiovascular disease risk, and comorbidities need to be recognized. Careful attention to recommended procedures for blood pressure measurement, conducting a history, performing a physical examination, and using laboratory tests will allow the physician to confirm the presence of hypertension; to assess its effects on target organs; to determine cardiovascular risk status relating to other factors; and to identify other diseases, laboratory abnormalities, or psychosocial factors that may affect subsequent management.
