Recent advancements in the medical field have significantly improved the diagnosis and treatment of ischemic heart disease. Furthermore, myocardial infarction without coronary artery obstruction, known as myocardial infarction with non-obstructive coronary arteries (MINOCA), has gained recognition. The etiology of MINOCA as a “working diagnosis” can be attributed to coronary, myocardial, and non-cardiac disorders. Understanding the “working diagnosis” of MINOCA, comprehending its underlying conditions, and carrying out appropriate diagnostic methods for each etiology to provide cause-specific treatment is necessary. We present a clinical overview of MINOCA, including its diagnosis, and a detailed review of each underlying condition.
