Intravascular ultrasound Guided PCI may lower risk of death, heart attack: JACC

USA: Intravascular ultrasound (IVUS) guidance although used infrequently in PCI procedure but when used it lowers long-term mortality, repeat revascularization, and heart attack risk, suggests a recent study in the journal JACC: Cardiovascular Interventions.

In real-world the benefit of the use of IVUS for guiding percutaneous coronary intervention (PCI) procedures is uncertain. Amgad Mentias, Division of Cardiovascular Medicine, University of Iowa Carver College of Medicine, Iowa City, Iowa, and colleagues, therefore, sought to explore if IVUS use in real-world patients is associated with improved long-term outcomes of PCI.

The researchers identified Medicare patients who underwent PCI from 2009 to 2017. They then evaluated the association of IVUS use with long-term risk of mortality, myocardial infarction (MI), and repeat revascularization. Propensity score matching and inverse probability weighting were used to adjust for baseline characteristics. Patients undergoing IVUS-guided PCI were matched to non-IVUS patients in the same hospital and year in order to account for hospital effects.
