Description
Summary:	Abstract Background Acute myocardial infarction (AMI) without obstructive coronary arteries (MINOCA) is a medical condition of great relevance, with clinical characteristics of AMI, but without evidence of coronary artery obstruction. The mechanism involved in the pathophysiology of the disease and its possible etiologies are important objects of study due to their impact on the morbidity and mortality of affected patients. Objectives The aim of this study was to systematically review MINOCA and its characteristics, with emphasis on the clinical profile of patients, etiology, pathophysiology, diagnosis, and treatment of the syndrome. Methods Relevant articles related to MINOCA were analyzed in the PubMed and LILACS databases. In the initial search stage, 619 eligible articles were obtained, with final inclusion criteria being: original systematic reviews with clinical, epidemiological, diagnostic, or treatment data on MINOCA, published in Portuguese or English, with an abstract, and a publication date limit of September 2020. Results A total of 10 articles classified as systematic reviews that considered clinical data on MINOCA were included in this review. Conclusion After analyzing various literature, the present study provided a tool to better understand MINOCA, not only regarding its casuistry but also in grouping parameters and information that contribute to a healthy approach to this clinical situation. It was possible to identify and better outline the clinical profile of patients who presented this condition and the use of appropriate tools for correct diagnosis and ideal treatment.
