Abstract
Dual antiplatelet therapy (DAPT) with acetylsalicylic acid and a P2Y12 inhibitor is an established therapy for a broad spectrum of patients with cardiovascular disease. The ischemic benefit of DAPT is partially offset by its increased bleeding risk, with intracranial hemorrhage (ICH) being the most serious complication. Although uncommon (0.2%-0.3% annually), its cumulative burden can be substantial given the number of patients afflicted by cardiovascular disease worldwide. Patients with a history of stroke or transient ischemic attack harbor a particularly high risk for ICH when treated with DAPT. Prediction rules may assist clinicians when weighing the risk/benefit ratio of prescribing DAPT for patients with stroke/transient ischemic attack in the nonacute, ambulatory setting. Currently, there are no reversal agents that can rapidly and effectively reverse the effect of P2Y12 inhibitors in routine practice, although a reversal agent for ticagrelor is under clinical investigation.
