Clinical Observation on Ambulatory Blood Pressure or the Hypertension Patients with Stroke

To explore circadian rhythm of blood pressure in the hypertension patients with stroke. Methods: 45 cases of hypertension with stroke and 27 cases of hypertension with non-stroke were measured by ambulatory blood pressure. Results: There was no significant difference (P0. 05) between average 24-hours systolic diastolic pressure and that of the daytime pressure. The average nighttime systolic diastolic pressure in the stroke group were remarkablely higher(P0. 01) than that of the non-stroke group. Blood pressure load was non-dippers type, but significant difference (P0. 05) existed between the two groups. Conclusion: Among the hypertension patients with stroke, the average nighttime blood pressure was higher than that of the daytime, and the circadian rhythm was disappeared.
