Infarto do miocárdio: alterações morfológicas e breve abordagem da influência do exercício físico

Abstract

Cardiovascular diseases are the leading cause of mortality and disability in Brazil and worldwide, with acute myocardial infarction (AMI) being one of the most common coronary diseases. This reflects cardiac myocyte death caused by an imbalance between the supply and demand of nutrients to the tissue caused by obstruction of the coronary flow, which may be a transient or permanent condition. Based on this information, a review of the literature was conducted in bibliographical databases and book collections, providing input for a study of morphological changes in AMI and morphological variations that may lead to the appearance of this pathology. There are several works on this subject, although few explore morpho-functional alterations to the cardiovascular system. Some studies reported improved cardiac function and remodeling, together with a decrease in atherosclerotic plaque, among patients undergoing cardiac rehabilitation.
