- Background: The absolute benefit of drug-eluting stents (DES) in low-risk patients and lesions is not well
Hypothesis: The long term clinical outcomes after percutaneous coronary intervention in a single coronary
artery disease may not be affected by the type of stent.
Methods: This study assessed and compared 2-year clinical outcomes of 304 consecutive patients (147 BMS
patients and 157 DES patients) treated with a single coronary stent (4.0 mm) for single de novo large coronary
artery disease in 3 referral cardiac centers. The primary outcome was a composite of major adverse cardiac
events at 2 years after the index procedure.
Results: The reference vessel diameter was similar in both groups (3.92 ± 0.29 mm in BMS vs 3.95 ± 0.24 mm
in DES, P = 0.50). Late loss was larger in the BMS group (1.04 ± 0.83 mm vs 0.73 ± 0.91 mm in DES,
P = 0.03). The incidence of major adverse cardiac events at the 2-year clinical follow-up was very low, 24 of
304 patients (7.9%), regardless of stent type deployed (7.5% in BMS vs 8.3% in DES, P = 0.83).Therateof
target vessel revascularization was also similar in both groups (4.8% in BMS vs 5.7% in DES, P = 0.80).
Conclusions: Two-year clinical outcomes after PCI with a single large coronary stent (4.0 mm) were excellent.
The clinical outcomes were not affected by the type of stent used.
