[An analysis of characters and changes of the blood pressure in 29 cases on recurrence of cerebral infarction].
We investigated changes of the blood pressure in 29 stroke patients before stroke recurrence and after recurrence. Additional antihypertensive drugs were not administered to all patients after stroke recurrence. Twenty-five lacunar infarct patients and 4 atherothrombotic infarct patients were included in this study. A significant difference was observed between the systolic blood pressure(SBP) within 4 weeks before recurrence and that just after recurrence(132.8 +/- 17.2 mmHg vs. 157.4 +/- 21.3 mmHg, Wilcoxon rank sum test, p < 0.001), or between the SBP just after and 2 weeks after stroke recurrence(157.4 +/- 21.3 mmHg vs. 138.0 +/- 18.3 mmHg, Wilcoxon rank sum test, p < 0.001). The similar difference was found in the diastolic blood pressure(DBP) or in the mean arterial blood pressure(MABP). There was no significant difference in the SBP, the DBP or the MABP between the patients before and 2 weeks after the stroke recurrence. These results suggested that the elevation of the blood pressure at recurrence decreased spontaneously to the pre-recurrence level of the blood pressure in about 2 weeks.
