Key result
OCT plus CMR identifies a mechanism in 100% of MINOCA patients versus OCT alone.
Why the study?
Scientific statements recommend multimodality imaging in MINOCA to define the underlying cause, but the diagnostic yield of combining OCT and CMR needed evaluation.
Does multimodality imaging with OCT and CMR improve the identification of underlying causes in patients with MINOCA compared to OCT alone?
Population
10 patients with MINOCA without previous coronary interventions
Comparison
Three-vessel OCT followed by CMR vs OCT alone
Design
Prospective, single center, observational pilot study

May improve etiological diagnosis in MINOCA; leaves open whether routine multimodality imaging alters management or outcomes.
Observational (n=10)
No
Does multimodality imaging with OCT and CMR improve the identification of underlying causes in patients with MINOCA compared to OCT alone?
Absolute Event Rate: 100% vs 70%
Multimodality imaging combining OCT and CMR identified the underlying mechanism in 100% of patients with MINOCA, highlighting its potential to guide secondary prevention.
Fluder-Wlodarczyk et al. (2022) conducted an observational in Myocardial infarction with non-obstructive coronary arteries (MINOCA) (n=10). Multimodality imaging with OCT and CMR vs. OCT alone was evaluated on Identification of the mechanism of MINOCA. Multimodality imaging with OCT and CMR identified a potential mechanism in 100% of patients with MINOCA, compared to 70% when using OCT alone.
