ABSTRACT
BACKGROUND:
Long-term outcome of drug-eluting stents (DES) for ST-elevation myocardial infarction (STEMI) versus non-ST-elevation acute coronary syndrome (NSTE-ACS) remains unclear. This study sought to compare the long-term outcomes of biodegradable polymer-coated DES in patients with STEMI versus NSTE-ACS.METHODS:
We explored a post hoc analysis of the 5-year outcome of the CREATE trial in the subgroup of patients with STEMI (n=318) versus NSTE-ACS (n=1223) who were implanted with biodegradable polymer-coated DES. The primary outcome was the rate of major adverse cardiac events (MACE) at 5 years. Clopidogrel and aspirin for 6 months followed by chronic aspirin therapy were recommended.RESULTS:
STEMI patients showed a trend of increase in MACE (8.7% vs. 6.8%, log rank p=0.289) compared to NSTE-ACS patients at 5 years, and a greater risk of cardiac death (5.4% vs. 2.1%, log rank p=0.003), mainly driven by the higher cardiac death rate within the first month after stent placement (log rank p=0.003) and the last year of follow-up (log rank p=0.001). No significant difference in stent thrombosis was found between them (3.1% vs. 2.5%, log rank p=0.653). Prolonged clopidogrel therapy (>6 months) showed no effect on risk of MACE or stent thrombosis between the two groups (both p for interaction >0.1).CONCLUSIONS:
STEMI patients have a higher risk of cardiac mortality compared with NSTE-ACS patients after biodegradable polymer-coated DES placement, primarily attribute to more cardiac deaths that happened within the first month after the event and the last year of follow-up.Key words
