Retrospective cohort study compares cardiac function and quality of life in IVUS versus angiography-guided PCI in ACS patients.

IVUS-guided PCI demonstrated superior outcomes, improving cardiac function and quality of life compared to angiography-guided methods.
The IVUS group showed a significant reduction in stent and neointima volumes at 9 months, indicating better procedural success.
Procedural complexity was higher for IVUS, with longer times and increased contrast use, though benefits outweighed drawbacks.
Quality of life improvements were observed, particularly in physical and social function scores, favoring IVUS guidance.

Zhao et al. (2025) studied this question.
