Key result
A 1680-kJ meal induced a 17±2 mm Hg decline in supine mean arterial blood pressure in 8 of 16 elderly patients with unexplained syncope (P<.001).
Why the study?
Does a meal induce postprandial hypotension and alter hemodynamic parameters in elderly patients with unexplained syncope compared to controls?
Population
16 elderly patients with unexplained syncope and 9 elderly controls (total n=25)
Comparison
1680-kJ meal vs Elderly controls without syncope
Design
Case-control

Postprandial hypotension may contribute to unexplained syncope in elderly patients; hypothesis-generating, larger prospective studies needed before clinical adoption.
Case-Control (n=25)
Does a meal induce postprandial hypotension and alter hemodynamic parameters in elderly patients with unexplained syncope compared to controls?
p-value: p=<.001
Postprandial hypotension may be an important causative factor in elderly patients with unexplained syncope, driven by splanchnic blood pooling without a compensatory increase in peripheral vascular resistance.
R. W. Jansen (1995) conducted a case-control in Unexplained syncope (n=25). 1680-kJ meal vs. Elderly controls without syncope was evaluated on Change in supine mean arterial blood pressure after a meal (p=<.001). A 1680-kJ meal induced a 17±2 mm Hg decline in supine mean arterial blood pressure in 8 of 16 elderly patients with unexplained syncope (P<.001).
