Tailored Anti-platelet Therapy After DES Implantation in High-risk Patients

Clopidogrel monotherapy has been found effective in reducing ischaemic cardiovascular and haemorrhagic complications in patients with drug-eluting stent (DES) placement. However, concerns remain about the safety of long-term clopidogrel monotherapy in high-risk patients with HPR (high platelet reactivity) who do not respond adequately to clopidogrel. This study aims to evaluate the effectiveness of a patient-tailored antiplatelet therapy strategy that considers platelet aggregation in high-risk patients with DES placement beyond 12 months after stenting.
