  • Efficacy and safety of intravascular ultrasound and coronary angiography in the left main coronary artery disease: a meta-analysis

    ObjectivesTo systematically review the efficacy and safety of intravascular ultrasound (IVUS) and coronary angiography-guided percutaneous coronary intervention (PCI) in left main coronary artery disease. MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) and cohort studies on the efficacy and safety of IVUS and coronary angiography-guided PCI in left main coronary artery disease from inception to March, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies; then, meta-analysis was performed using RevMan 5.3 software.ResultsA total of 7 studies involving 7 777 patients were included. The results of meta-analysis showed that: compared with PCI guided by coronary angiography, the incidence of cardiac death (OR=0.45, 95%CI 0.34 to 0.61, P<0.000 01), myocardial infarction (OR=0.67, 95%CI 0.53 to 0.84, P=0.004), major adverse cardiovascular events (OR=0.46, 95%CI 0.34 to 0.61, P<0.000 01), total deaths (OR=0.54, 95%CI 0.44 to 0.67, P<0.000 01), and in-stent thrombosis (OR=0.28, 95%CI 0.18 to 0.45, P<0.000 01) occurred in PCI guided by IVUS were lower. The differences were statistically significant. However, there were no statistical significance in the incidence of target revascularization in PCI (OR=0.80, 95%CI 0.40 to 1.61, P=0.54) and revascularization of target lesions (OR=0.68, 95%CI 0.36 to 1.27, P=0.23) between two groups.ConclusionsCurrent evidence shows that the IVUS-guided PCI can decrease the incidence of cardiac death, myocardial infarction, MACEs, stent thrombosis, total death and has no effect on target lesion revascularization and target vessel revascularization. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusion.
