Abstract

Abstract Ischemic cardiomyopathy is one of the major health problems worldwide, representing a significant part of mortality in the general population nowadays. Cardiac magnetic resonance imaging (CMRI) and cardiac computed tomography (CCT) are noninvasive imaging methods that serve as useful tools in the diagnosis of coronary artery disease and may also help in screening individuals with risk factors for developing this illness. Technological developments of CMRI and CCT have contributed to the rise of several clinical indications of these imaging methods complementarily to other investigation methods, particularly in cases where they are inconclusive. In terms of accuracy, CMRI and CCT are similar to the other imaging methods, with few absolute contraindications and minimal risks of adverse side-effects. This fact strengthens these methods as powerful and safe tools in the management of patients. The present study is aimed at describing the role played by CMRI and CCT in the diagnosis of ischemic cardiomyopathies.Resumo A cardiomiopatia isquêmica é um dos principais problemas de saúde no mundo, representando significativa parcela da mortalidade. A ressonância magnética cardíaca (RMC) e a tomografia computadorizada cardíaca (TCC) são métodos de imagem não invasivos úteis no diagnóstico da doença arterial coronariana e também podem auxiliar no rastreamento de indivíduos com fatores de risco para o desenvolvimento de cardiomiopatia induzida por isquemia/infarto. Os avanços tecnológicos da RMC e da TCC contribuíram para o surgimento de diversas indicações clínicas para aplicação desses métodos de imagem de forma complementar a outros exames, principalmente quando estes se mostram inconclusivos. A RMC e a TCC apresentam acurácia semelhante aos demais métodos de imagem, poucas contraindicações absolutas e mínimos riscos de efeitos adversos, o que os fortalecem como ferramentas seguras no manejo dos pacientes. O presente estudo tem por objetivo descrever o papel da RMC e da TCC no diagnóstico das cardiomiopatias isquêmicas.
