目的：观察老年脑梗塞患者恢复期血压昼夜变化的方式及可能影响的因素。方法：应用２４ 小时血压监测仪测定４５ 例老年半球梗塞患者昼夜血压变化，并与年龄、性别、血压情况相似的老年非脑梗塞者进行比较。结果：老年脑梗塞患者恢复期的昼夜平均收缩压和舒张压与对照组相比无显著差异，而昼夜收缩压相对差小于对照组（ Ｐ＜ ０ ．０５） ，原有高血压史的脑梗塞患者的昼夜收缩压相对差（ Ｐ＜ ０ ．０１） ，昼夜收缩压百分率（ Ｐ＜ ０ ．０５） ，昼夜舒张压相对差（ Ｐ〈０ ．０５） 显著低于对照组。结论：提示有高血压史的脑梗塞患者恢复期的血压昼夜变化仍有异常。
Objective: To observe the changes of circadian blood pressure during convalescence in elderly patients with cerebral infarction and the possible influencing factors. Methods: The changes of diurnal blood pressure in 45 elderly patients with hemispheric infarction were measured by 24-hour blood pressure monitor and compared with those of non-cerebral infarction patients with similar age, sex and blood pressure. Results: The average systolic and diastolic blood pressure in convalescence of elderly patients with cerebral infarction had no significant difference compared with the control group, but the difference of day and night systolic pressure was less than that of the control group (P <0.05) The diurnal and systolic blood pressure (P <0.01), diurnal and systolic blood pressure (P <0. 05) and diurnal diastolic pressure (P <0. 05) were significantly lower than those of the control group. CONCLUSIONS: Circadian blood pressure changes during the convalescence of patients with a history of hypertension are suggestive of abnormalities.
