Utilization of IVUS improves all-cause mortality in patients undergoing invasive coronary angiography.

ABSTRACT: Background and aims
Available data suggest that the use of IVUS for guidance of percutaneous coronary interventions (PCIs) improves the prognosis of patients undergoing complex interventions. We aimed to examine how the utilization of intravascular ultrasound (IVUS) affects patient survival irrespective of procedure complexity.Methods
The present analysis is based on the longitudinal ECAD registry of consecutive patients undergoing coronary angiography between 2004 and 2019. The incidence of death due to any cause was evaluated during a mean follow-up of 3.4 years. Cox regression analysis was used to determine the association of IVUS utilization with incident mortality.Results
Overall, data from 30,814 coronary angiography exams (mean age 64.9 ± 12.5 years, 70.3% male) were included, among which 4991 procedures (16.2%) were guided by IVUS. Utilization of IVUS was associated with a 35% reduction in mortality, independent of traditional risk factors (0.64(0.58-0.71), p < 0.0001). The effect of IVUS on mortality was equally present in patients undergoing IVUS-guided coronary interventions (0.75[0.67-0.84], p < 0.0001) as well as purely diagnostic coronary angiography exams (0.62[0.56-0.72], p < 0.0001). In patients without coronary intervention, IVUS utilization led to a higher frequency of aspirin (82.6% vs. 61.9% for IVUS vs. no IVUS, p < 0.0001) and statin therapy (74.9% vs. 62.5%, p < 0.0001).Conclusions
In a large longitudinal registry cohort of patients undergoing invasive coronary angiography, IVUS utilization was associated with lower long-term mortality. The beneficial role of IVUS utilization on survival was equally present for coronary interventions and diagnostic coronary angiograms. Our results support the use of intravascular imaging for decision making in interventional cardiology.
