: Subjects affected by ischemic heart disease with non-obstructive coronary arteries constitute a population that has received increasing attention over the past two decades. Since the first studies with coronary angiography, female patients have been reported to have non-obstructive coronary artery disease more frequently than their male counterparts, both in stable and acute clinical settings. Although traditionally considered a relatively infrequent and low-risk form of myocardial ischemia, its impact on clinical practice is undeniable, especially when it comes to infarction, where the prognosis is not as benign as previously assumed. Unfortunately, despite increasing awareness, there are still several questions left unanswered regarding diagnosis, risk stratification and treatment. The purpose of this review is to provide a state of the art and an update on current evidence available on gender differences in clinical characteristics, management and prognosis of ischemic heart disease with non-obstructive coronary arteries, both in the acute and stable clinical setting.

Myocardial infarction with non-obstructive coronary artery disease (MINOCA) is a working diagnosis for patients presenting with acute myocardial infarction without obstructive coronary artery disease on coronary angiography. It is a heterogenous entity with a number of possible etiologies that can be determined through the use of appropriate diagnostic algorithms. Common causes of a MINOCA may include plaque disruption, spontaneous coronary artery dissection, coronary artery spasm, and coronary thromboembolism. Optical coherence tomography (OCT) is an intravascular imaging modality which allows the differentiation of coronary tissue morphological characteristics including the identification of thin cap fibroatheroma and the differentiation between plaque rupture or erosion, due to its high resolution. In this narrative review we will discuss the role of OCT in patients presenting with MINOCA. In this group of patients OCT has been shown to reveal abnormal findings in almost half of the cases. Moreover, combining OCT with cardiac magnetic resonance (CMR) was shown to allow the identification of most of the underlying mechanisms of MINOCA. Hence, it is recommended that both OCT and CMR can be used in patients with a working diagnosis of MINOCA. Well-designed prospective studies are needed in order to gain a better understanding of this condition and to provide optimal management while reducing morbidity and mortality in that subset patients.
