Why the study?
MINOCA is clinically distinct and heterogeneous, yet its prognosis and predictors remain uncertain and traditional one-size-fits-all treatments used for obstructive disease may not be appropriate.
MINOCA requires individualized diagnostic and treatment strategies due to its diverse underlying causes, contrasting with the standard approach for obstructive coronary artery disease.

MINOCA prognosis and predictors remain uncertain; leaves open need for dedicated prospective studies to guide risk stratification.
Myocardial infarction with non-obstructive coronary arteries (MINOCA) is defined as clinical evidence of myocardial infarction (MI) without significant obstruction (<50 % stenosis) in coronary angiography, making it a clinically distinct and heterogeneous disorder. Unlike MI associated with obstructive coronary artery disease (MICAD), MINOCA is more common in younger women and often involves microvascular dysfunction or vasospastic conditions. Despite recent advancements in understanding MINOCA, its prognosis and predictors remain uncertain, necessitating further research into its pathogenesis. The diverse underlying causes of MINOCA mean that traditional treatment of the "one-size-fits-all" approach used for MICAD may not be appropriate, emphasizing the need for individualized treatment strategies based on accurate diagnosis. There is an urgent need to raise awareness among healthcare providers, implement standardized diagnostic protocols, and conduct targeted research to improve patient outcomes. Multi-centered studies and clinical trials are essential to establish evidence-based therapies and optimize management strategies for MINOCA, ensuring better long-term outcomes.
