Abstract

Spontaneous subarachnoid hemorrhage is mostly caused by the rupture of an aneurysm. Neurogenic stunned myocardium (NSM) is one of the most frequent complications caused by aneurysmal subarachnoid hemorrhage (aSAH). The possible pathogenesis of NSM may be that the catecholamine peak resulting from aSAH leads to subendocardial ischemia or coronary artery spasm. We designed this meta-analysis to find out whether beta-blockers (BB) can significantly reduce the incidence of NSM and improve the outcomes of aSAH. We systematically searched PubMed, Embase, Cochrane library, Elsevier and Medline from inception to Feb 2016. All studies related to the preadmission beta-blocker with aSAH were included. Three retrospective studies and 691 patients were included. The incidence of mortality [OR=0.68, 95%CI (0.08-3.50), P=0.57], cardiac dysfunction [OR = 0.55, 95% CI (0.05-6.49), P=0.63], cerebral vasospasm (OR=0.52 95% CI(0.18-2.56), P=0.50] had no statistical difference between the preadmission BB group and no BB group. The preadmission beta-blocker cannot decrease the incidence of mortality, cardiac dysfunction, cerebral vasospasm in patients with aSAH. A further research of the usefulness of preadmission beta-blocker in patients with aSAH ...Continue Reading
