Original ArticleContribution of Deep Microbleeds to Stroke Recurrence: Differences between Patients with Past Deep Intracerebral Hemorrhages and Lacunar Infarctions
Section snippets
Subjects
From April 2004 to December 2011, we enrolled patients consecutively admitted to our hospital within 7 days of experiencing deep ICHs or LIs (index strokes). Follow-up took place until March 2014 at the latest, and stroke recurrences were evaluated in all patients. We excluded patients with follow-up durations of less than 1 week, and those with unclear findings on MRIs due to motion or metal artifacts. All study procedures were approved by the Ethics Committee of Kushiro City General Hospital
Patients with Lacunar Infarctions as Index Strokes (LI Patients)
We consecutively enrolled 337 LI patients during the study period. Twenty-eight patients were excluded, including 6 with pacemakers, 7 who died within 7 days after the index stroke onset, 5 with unclear findings on MRIs, and 10 with insufficient records. Thus, 309 of the initial 337 LI patients were followed and stroke recurrences were investigated. The 309 patients were divided into 2 groups, those with deep MBs and those without. Table 1 presents stroke-related variables in the 2 groups.
Discussion
In this study, we examined the differences between patients with histories of deep ICHs and LIs in terms of the contribution of preexisting deep MBs to stroke recurrence.
