Authors' conclusion

In this updated meta-analysis of RCTs, after accounting for modifier effects from recent studies, ICI-guided PCI was associated with significantly reduced cardiovascular events compared with angiography-guided PCI. Geographic heterogeneity across trials was present mainly for target vessel revascularization, explained in large part by differences in lesion characteristics and procedural technique.

Study context

Population
Patients undergoing percutaneous coronary intervention (PCI) in the drug-eluting stent era
Participants
24,634 patients · 28 randomized controlled trials (RCTs)
Comparison
Intracoronary imaging (ICI)-guided PCI vs angiography-guided PCI

Pooled result

As reported in the abstract

Target lesion failure, cardiac mortality, MI, target vessel revascularization, stent thrombosis and all-cause mortality · mean follow-up 22 months
ICI-guided PCI vs Angiography-guided PCIRR
target lesion failure; I2 = 61%
0.72(95% CI 0.61–0.85)
cardiac mortality; I2 = 5%
0.73(CI 0.58–0.91)
MI; I2 = 0%
0.86(CI 0.75–0.97)
target vessel revascularization; I2 = 41%
0.69(95% CI 0.57–0.83)
stent thrombosis; I2 = 0%
0.55(95% CI 0.40–0.76)
all-cause mortality; I2 = 0%
0.82(95% CI 0.70–0.96)
