This meta-analysis evaluated the clinical outcomes of intravascular ultrasound (IVUS)-guided versus angiography-guided percutaneous coronary intervention (PCI) in patients with unprotected left main coronary artery disease (ULMCAD). Analyzing data from four randomized controlled trials involving 1446 patients, the study found no significant difference in major adverse cardiovascular events (MACE) between the two approaches (RR 0.57, 95% CI 0.30-1.09; P = 0.09).
Key findings
- No significant difference in MACE between IVUS-guided and angiography-guided PCI (RR 0.57, 95% CI 0.30-1.09; P = 0.09).
- Cardiac mortality rates were similar between the two groups (RR 0.68, 95% CI 0.27-1.73; P = 0.41).
- No significant differences in myocardial infarction rates (RR 0.93, 95% CI 0.68-1.28; P = 0.66).
- Target lesion revascularization rates were comparable (RR 0.67, 95% CI 0.36-1.22; P = 0.18).
Why it matters
Understanding the effectiveness of IVUS-guided PCI compared to traditional angiography-guided PCI is crucial for optimizing treatment strategies in patients with ULMCAD, potentially impacting clinical decision-making and patient outcomes.
