Abstract

Background and aims: Myocardial infarction complicating acute ischemic stroke (IS) is associated with high mortality, but evidence guiding the acute management is scarce. In particular, data on the risk of intracerebral hemorrhage (ICH) due to early cardiac catheterization including the peri-procedural application of antithrombotic drugs in patients with acute ischemic stroke are limited. Here, we aimed to evaluate the incidence and patient characteristics of ICH after cardiac catheterization in acute stroke patients to help to govern the risk of intracranial bleeding versus the benefits of myocardial reperfusion via cardiac catheterization. Methods: We screened a consecutive cohort of n =126 patients with acute ischemic stroke (IS) who underwent cardiac catheterization during the same hospital stay at a large German neurovascular center (LMU Munich). Eventually, we identified n = 42 patients with cardiac catheterization after acute stroke. N = 22/42 patients did not receive neuroimaging post cardiac catheterization and were discharged without any new neurological deficits, n = 20/42 had neuroimaging after cardiac catheterization and were included for final analysis. Results: Cardiac catheterization was performed within a median of 3,6 days after ischemic stroke (No-ICH 7,3 days (IQR, 3,8-16,2) vs. ICH 1,1 days (IQR, 0,8-74,6), p = 0,40), One patient showed new neurological deficits after cardiac procedures (n =1/42, 2,4 %). New or progressive ICH was ultimately found in 15 % (3/20) of cases. They were classified as HT1, PH1 and PH2 according to ECASS II criteria, respectively. With regards to the coronary catheterization, 85 % of all patients undergoing catheterization ultimately received percutaneous cardiac intervention. ICH was not significantly associated with any of the independent variables. Intrahospital death due to either ischemic stroke, ICH or cardiovascular events did not occur. Conclusion: The incidence of ICH in ischemic stroke followed by early cardiac catheterization and application of antithrombotic drugs was comparable to studies reporting on the incidence of ICH in ischemic stroke patients without catheterization. This study's results strengthen the hypothesis that in presence of both, acute myocardial infarction and acute ischemic stroke, the general risk for ICH is not prohibitive of cardiac catheterization.
