[A case of postprandial hypotension in an elderly subject].
This is a case report of a 74-year old woman who from March 1994 to April 1995 was admitted to our hospital because of three episodes of syncope. Each general physical examination was normal except for a grade 2/6 systolic murmur. No abnormalities were disclosed after several resting electrocardiograms and Holter monitoring. The Schellong and the tilt tests were normal. During the last admission the patient had a syncope 30 minutes after a meal. Blood pressure reduction was documented and postprandial hypotension was diagnosed. Postprandial decreases in systolic blood pressure in the elderly may predispose the subject to symptomatic hypotension and to falls, dizziness, weakness, angina pectoris, stroke and syncope. The mechanism of postprandial hypotension is not fully understood. It is defined as a decrease in postprandial systolic blood pressure of 20 mmHg or more. Because postprandial hypotension is a common problem in older, frail, institutionalized patients, all physicians caring for elderly patients should be aware of the hypotensive effects of food intake and should consider postprandial hypotension in the evaluation of falls, syncope and other ischemic cerebral symptoms.
