Abstract
Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a puzzling clinical phenomenon with an unclear prognosis, characterized by evidence of myocardial infarction (MI) with normal or near-normal coronary arteries on angiography1. Currently, there are no guidelines for management, and many patients are discharged without a determined etiology, often meaning that optimal treatment gets postponed.We report three MINOCA case studies with main pathophysiological cardiac causes, particularly epicardial, microvascular, and non-ischemic, prompting differential management. The patients presented with acute chest pain, troponin raise, and no angiographically significant coronary disease.In this study, we analyzed the etiology, clinical diagnosis, and treatment of MINOCA concerning the relevant literature.MINOCA is considered to be a dynamic working diagnosis, including coronary, myocardial, and non-coronary disorders. Prospective studies and registries are needed to improve patient care and outcome.
期刊介绍：
With more than 70 years of existence, Arquivos Brasileiros de Cardiologia is the main channel for the dissemination of Brazilian scientific research on cardiovascular sciences. Published in two languages and indexed in major international databases, all scientific contributions are peer-reviewed and reviewed by editorial board members selected among the most reputable researchers in Brazil and abroad. The manuscripts are reviewed according to their relevance and originality, scientific accuracy and level of importance for the advancement of science. With an average time of nine months between the initial submission and the effective publication of the manuscripts, and less than seven months until they are published on PubMed, Arquivos Brasileiros de Cardiologia can ensure the quick inclusion of the researchers’ papers in the international literature.
