对 11 名门诊（主动组，78 +/- 2 岁）和 11 名卧床不起（被动组，79 +/- 2 岁）老年患者进行了无创测量 24 小时血压 (BP)。两组的餐后血压均明显下降。主动组白天的血压变异性明显大于被动组。因此，只有被动组的患者表现出显着的血压昼夜差异以及显着的血压昼夜节律。我们得出以下结论：1）餐后血压降低会导致老年患者白天血压变异性，2）卧床患者中较大的血压变异性掩盖了血压的昼夜节律，3）卧床患者中存在血压的昼夜节律。
Twenty-four-hour blood pressure (BP) was determined noninvasively in 11 ambulatory (active group, 78 +/- 2 years old) and 11 bedridden (passive group, 79 +/- 2 years old) elderly patients. Postprandial reduction in BP was evident in both groups. BP variability during the daytime was significantly greater in the active group than in the passive group. Consequently, only patients of the passive group showed a significant day-night difference in BP and a significant circadian rhythm of BP as well. We conclude the following: 1) postprandial reduction in BP contributes to BP variability during daytime in elderly patients, 2) the greater BP variability seen in ambulatory patients obscures the day-night rhythm of BP, and 3) the day-night rhythm of BP exists in bedridden patients.
