Abstract
Background
Adjunctive thrombus aspiration (
TA
) during primary percutaneous coronary intervention (
PCI
) was reported to promote better coronary and myocardial reperfusion. However, long‐term mortality benefit of
TA
remains controversial. The objective of this study is to investigate the clinical impact of
TA
on long‐term clinical outcomes in patients with
ST
‐segment elevation myocardial infarction (STEMI) undergoing primary
PCI
.
Methods and Results
The
CREDO
‐Kyoto
AMI
Registry is a large‐scale cohort study of acute myocardial infarction patients undergoing coronary revascularization in 2005–2007 at 26 hospitals in Japan. Among 5429 patients enrolled in the registry, the current study population consisted of 3536 patients who arrived at the hospital within 12 hours after the symptom onset and underwent primary
PCI
. Clinical outcomes were compared between the 2 patient groups with or without
TA
. During primary
PCI
procedures, 2239 out of 3536 (63%) patients underwent
TA
(
TA
group). The cumulative 5‐year incidence of all‐cause death was significantly lower in the
TA
group than in the non‐
TA
group (18.5% versus 23.9%, log‐rank
P
<0.001). After adjusting for confounders, however, the risk for all‐cause death in the
TA
group was not significantly lower than that in the non‐
TA
group (hazard ratio: 0.90, 95%
CI
: 0.76 to 1.06,
P
=0.21). The adjusted risks for cardiac death, myocardial infarction, stroke, and target‐lesion revascularization were also not significantly different between the 2 groups.
Conclusions
Adjunctive
TA
during primary
PCI
was not associated with better 5‐year mortality in STEMI patients.
