Intravascular Imaging- vs Angiography-Guided Complex Percutaneous Coronary Intervention (PCI): 5-Year Outcomes From a Randomized Trial
Primary resultResult — go to the resultHazard ratio 0.68 95% CI 0.51–0.91Authors' conclusion
In patients with complex coronary artery lesions undergoing PCI, intravascular imaging guidance reduced the risk of a composite of cardiac death, target vessel-related myocardial infarction, or clinically driven target vessel revascularization at median follow-up of 5.3 years, compared to angiography guidance.
