Therapeutic strategies aiming at the reduction of the antiplatelet intensity should not overlook the ischemic risk in patients with coronary syndromes

Abstract

De-escalation of dual antiplatelet therapy (DAPT) is gaining traction as a strategy to reduce bleeding risks while ensuring ischemic outcomes. Undiscriminating de-escalation, notably in patients with high ischemic risk, might expose them to major adverse cardiac events. Platelet function and genetic tests are emerging tools to guide de-escalation, but both present specific drawbacks. Recent meta-analyses have aimed to consolidate the findings of individual trials to provide clearer insights. Yet, limitations remain for patients with concomitant high bleeding and ischemic risks. These high-risk patients are frequently underrepresented in clinical trials, and, therefore, currently available guidelines lack evidence-based recommendations for this subset. While DAPT de-escalation strategies hold promise, the choice of approach, whether clinically or assay-guided, remains complex and should be individualized.
