[Tirofiban improved the prognosis of senior acute coronary syndrome patients received percutaneous coronary intervention].

Objective: To examine if tirofiban may improve the prognosis in aged acute coronary syndrome (ACS) patients received percutaneous coronary intervention (PCI).

Methods: Three hundred and twenty-five ACS patients (age ≥ 60 years), all received drug-eluting stents implantation, were assigned into tirofiban group (n = 210) to receive tirofiban+aspirin and clopidogrel and control group (n = 115) to received aspirin and clopidogrel only. The incidence of thrombolysis in myocardial infarction (TIMI) grade 3 after PCI, in-stent thrombosis, slight/severe bleeding, platelet decrease, myocardial infarction (MI) and target vessel revascularization (TVR) within 30 days and 12 months after PCI and 30 days and 12 months mortality post PCI.
