BackgroundCurrent guidelines recommend culprit-only revascularisation (COR) in haemodynamically stable patients with ST-segment elevation myocardial infarction (STEMI) and multivessel (MV) disease. Contrarily, growing body of evidence available from recent randomised controlled trials (RCTs) demonstrates improved outcomes with complete MV-percutaneous coronary intervention (PCI).Methods And ResultsWe performed a meta-analysis of RCTs comparing complete MV-PCI with non-complete MV-PCI in STEMI and MV disease. Complete MV-PCI was defined as revascularisation to non-infarct-related artery lesions during index procedure, non-complete MV-PCI-encompassed COR and staged approaches. Multiple databases and congress proceedings from major cardiovascular societies' meetings were screened for relevant studies. Primary endpoint was the composite of major adverse cardiac events (MACE) typically defined as death, recurrent myocardial infarction (MI) and repeat revascularisation. Secondary endpoints were cardiovascular mortality, recurrent MI and repeat revascularisation. Outcomes were analysed at longest available follow-up with differences accounted for with adjusted models by person-years. Seven RCTs (N=1303) were included. The median follow-up was 12 months. Complete MV-PCI reduced the odds of MACE compared with non-complete MV-PCI (OR (95% CIs) 0.59 (0.36 to 0.97), p=0.04) driven by reduction in recurrent MI (0.48 (0.27 to 0.85), p=0.01) and repeat revascularisation (0.51 (0.31 to 0.84), p=0.008). Complete MV-PCI was associated with a non-significant trend towards reduced cardiovascular mortality (0.54 (0.26 to 1.10), p=0.09) as well. In a sensitivity analysis, none of the baseline clinical variables significantly influenced overall estimates.ConclusionsIn STEMI and MV disease, complete MV-PCI as compared with non-complete strategy reduces MACE by 41%, driven by a 52% reduction in recurrent MI and 49% reduction in repeat revascularisation.Published by the BMJ Publishing Group Limited.
