Key result
Intracoronary imaging and vasomotor testing identify specific MINOCA etiologies to guide targeted therapy.
Why the study?
MINOCA is a working diagnosis where angiography alone typically does not identify specific etiologies, requiring additional diagnostic approaches to determine underlying pathogenic causes.
A comprehensive literature review highlighting that MINOCA is a working diagnosis requiring advanced diagnostic tools like IVUS, OCT, and provocation tests to identify the underlying etiology for targeted therapy.

Angiography alone fails to identify MINOCA etiology in most cases; extends need for targeted diagnostics in practice and trials.
The term MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries) refers to pathological conditions where there is evidence of myocardial necrosis due to a lack of blood flow but no significant coronary lesions are seen on angiography. This is working diagnosis, which requires careful investigation to identify specific causes: plaque rupture, coronary dissection, vasospasm, microvascular dysfunction, thromboembolism, etc. Angiography alone, in most cases, does not lead to an etiological diagnosis. So additional techniques like intracoronary imaging and vasomotor function tests are important, especially in younger patients. This literature review demonstrates the main pathogenic patterns and diagnostic approachs for MINOCA patients.

Sofiya Lypovetska (2024) conducted a review in Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA). Diagnostic approach and pathogenic pattern identification was evaluated. MINOCA is a heterogeneous condition requiring comprehensive diagnostic evaluation, including intracoronary imaging and vasomotor testing, to identify the specific etiology and guide targeted therapy.
