Drug-eluting stents (DESs) have been shown to reduce the rate of repeat revascularization
compared with bare-metal stents (BMSs) after multivessel percutaneous coronary inter-
vention in carefully selected patients. However, the long-term safety and efficacy of DESs
in patients with multivessel disease outside the setting of randomized trials was unknown.
Therefore, all patients undergoing multivessel percutaneous coronary intervention with
BMSs, sirolimus-eluting stents (SESs), or paclitaxel-eluting stents (PESs) from January
2000 to December 2005 were investigated. The primary end point was all-cause mortality.
A total of 1,720 patients were recruited in 3 consecutive sequential groups of BMS (n 701;
January 2000 to April 2002), SES (n 293; April 2002 to February 2003), and PES (n
726; February 2003 to December 2005). Overall median follow-up was 1,440 days. There
was improved 3-year survival in the SES group (93.7%) compared with both the BMS
(86.1%) and PES groups (87.3%), which remained significant after propensity score ad-
justment for differences in baseline and procedural characteristics (SES vs BMS, adjusted
hazard ratio 0.53, 95% confidence interval 0.30 to 0.94; SES vs PES, adjusted hazard ratio
0.49, 95% confidence interval 0.28 to 0.87). There was no difference in mortality between
the PES and BMS groups. Both DES types significantly reduced the need for clinically
driven target-vessel and target-lesion revascularization without an excess in myocardial
infarction or stent thrombosis. In conclusion, both SESs and PESs significantly reduced the
need for repeated revascularization in these patients with no excess in mortality. SESs
might reduce mortality in patients undergoing multivessel percutaneous coronary
intervention. © 2009 Elsevier Inc. (Am J Cardiol 2009;103:203–211)
Historically, coronary artery bypass grafting has been the
gold standard of treatment for patients with multivessel
coronary artery disease.

Trials comparing percutaneous
coronary intervention using bare-metal stents (BMSs) have
shown equivalent mortality, but an increased need for re-
peated revascularization compared with coronary artery by-
pass grafting.

The Arterial Revascularization Therapies
Study Part II (ARTS-II) found equivalent 3-year survival
with drug-eluting stents (DESs) compared with historic cor-
onary artery bypass grafting and BMS groups from ARTS-I,
although freedom from revascularization was still inferior to
coronary artery bypass grafting.

Nonetheless, with recent
revelations about late and very late stent thrombosis, there
were concerns regarding the long-term safety of DESs,
particularly in patients treated for “off-label” indications.

Although there were reports of short-term clinical outcomes
after multivessel percutaneous coronary intervention with
DESs,

longer term comparisons between BMSs and
different DESs in unselected patients with multivessel dis-
ease were scarce. We therefore analyzed all patients un-
dergoing multivessel percutaneous coronary intervention
in our institution to ascertain the long-term safety of
BMSs, sirolimus-eluting stents (SESs), and paclitaxel-
eluting stents (PESs).
Methods
From January 2000 to December 2005, all patients under-
going multivessel percutaneous coronary intervention with a
single stent type as their standard treatment were enrolled.
We defined multivessel percutaneous coronary intervention
as intervention to 2 major epicardial coronary arteries or
bypass grafts during the same procedure. Initially, all pa-
tients were treated with BMSs, but on April 16, 2002, our
institution adopted the use of SESs (Cypher; Cordis, War-
ren, New Jersey) as the default strategy for all coronary
interventions. On February 16, 2003, SESs were replaced
by PESs (Taxus; Boston Scientific, Natick, Massachusetts)
as the default stent. This single-center registry therefore
consisted of 1,720 patients divided into 3 groups of consec-
utive patients of BMS (n = 701; January 2000 to April
2002), SES (n = 293; April 2000 to February 2003), or PES
(n = 726; February 2003 to December 2005). The sole
exclusion criterion was implantation of 1 different stent
