Non-obstructive Plaque and Treatment of INOCA: More to Be Learned.

While there is scarce scientific evidence on management of INOCA, the CorMicA trial showed that stratified medical therapy based on the type of INOCA improved patients' symptoms and quality of life. There are multiple ongoing trials, including Women's IschemiA Trial to Reduce Events in Non-ObstRuctIve CORonary Artery Disease (WARRIOR trial), assessing the benefit of intensive medical therapy versus usual care for this increasingly recognized clinical entity. In this review, we discuss the definition of INOCA, epidemiology and risk factors, pathophysiology, and management as well as the current knowledge gaps and ongoing clinical trials in this arena.
