Initiation of antithrombotic therapy (antiplatelet or anticoagulant) after intracerebral hemorrhage (ICH) has long been a matter of conflict among clinicians dealing with stroke patients. Given that the treatment of ICH in the acute phase is mostly supportive, one can understand the anxiety of the clinicians who want to prevent an ICH recurrence. However, according to American Heart Association/American Stroke Association (AHA/ASA) guidelines, the recommendation that “anticoagulation after nonlobar ICH and antiplatelet monotherapy after any ICH might be considered, particularly when there are strong indications for these agents” is not well established (Class IIb) and is based on evidence derived from nonrandomized studies (Level of Evidence B). That is why studies aiming to shed light on this matter are more than welcome from the scientific community of stroke.
The study by Murthy et al. is an attempt to enrich the scarce data regarding the impact of antiplatelet therapy (APT) initiation after ICH on functional outcomes. For that reason, the authors separately analyzed data from 3 large cohort studies [ICH study at Massachusetts General Hospital (MGH), Virtual International Stroke Trials Archive-ICH (VISTA-ICH), ICH database of Yale University School of Medicine], consisting of 1801 ICH patients in total. Inclusion criteria were: diagnosis of primary ICH in CT-scan, age >18 years, and complete follow up at 90 days. Exclusion criteria were: previous history of ICH, secondary cause of ICH, and prior use of anticoagulants.
