Abstract

Background: Clinical disagreement over antiplatelet (AP) resumption in patients with primary intracranial hemorrhage (ICH) has long existed. This meta-analysis aimed to evaluate the benefits of AP resumption on preventing ischemic or thromboembolic events against its risks of promoting ICH recurrence or hematoma expansion.

Methods: All relevant articles published in Pubmed, EMBASE, the Cochrane Library, and Science Direct from January 1950 to March 2017 were sourced, and the combined relative risk (RR) was calculated.

Results: A total of 3648 articles were found, and after screening, 6 cohort studies including 1916 patients were included in this meta-analysis. AP resumption was associated with a decreased risk of ischemic or thromboembolic events (RR, 0.61; 95% confidence interval (CI), 0.48-0.79; P<0.01). There was no significant difference in the risk of ICH recurrence or hematoma expansion between patients with or without AP resumption (RR, 0.84; 95% CI, 0.47-1.51; P=0.56).

Conclusion: AP resumption in patients with primary ICH reduced the risk of ischemic or thromboembolic events, without significant increase of risk of ICH recurrence or hematoma expansion.
