The effect of postprandial hypotension on rehabilitation of the frail elderly with cerebrovascular disease.
A total of 15 elderly patients recovering from stroke were included in a random, observer-blind, crossover trial to investigate the effects of postprandial cardiovascular changes. Exercise capability, sitting and erect blood pressure and heart rate were recorded pre- and postprandially; a control group received water only. Exercise capability decreased significantly (P < 0.05) in the control group, but not in the test group. Systolic and diastolic blood pressures in the erect position post-exercise were significantly (P < 0.05) reduced in the test group 15 min after eating; in the control group there was no significant change. A significant (P < 0.05) increase in heart rate in the erect position was seen postprandially in the test group after exercise, but not in the control group. All other changes recorded did not reach statistical significance. No reduction in exercise capability occurred in patients exhibiting postprandial hypotension after food, as simultaneous increases in heart rate probably resulted in output being maintained.
