To the Editors: Most hypertensive and nonhypertensive subjects studied with 24-hour ambulatory blood pressure monitoring have a reproducible decrease in blood pressure during sleep. This normal diurnal pattern may be absent in one of three elderly subjects (1); pregnant subjects with pre-eclampsia; patients with malignant hypertension, sleep apnea, the Cushing syndrome, diabetes mellitus, orthostatic hypotension, or congestive heart failure; and cardiac transplant recipients (2). Patients with autonomic nervous system dysfunction may also lack a normal nocturnal decline in blood pressure (3).
