The study of myocardial viability is of great importance in the orientation and
management of patients requiring myocardial revascularization or angioplasty.
The technique of delayed enhancement (DE) is accurate and has transformed the
study of viability into an easy test, not only for the detection of fibrosis but
also as a binary test detecting what is viable or not. On DE, fibrosis equal to
or greater than 50% of the segmental area is considered as non-viable, whereas
that below 50% is considered viable. During the same evaluation, cardiac
magnetic resonance (CMR) may also use other techniques for functional and
perfusion studies to obtain a global evaluation of ischemic heart disease. This
study aims to highlight the current concepts and broadly emphasize the use of
CMR as a method that over the last 20 years has become a reference in the
detection of infarction and assessment of myocardial viability.
Almost two decades ago, it became possible to use coronary computed tomography for the noninvasive assessment of the coronary arteries. That is an extremely accurate method for detecting or excluding coronary artery disease, even the subclinical forms. This pictorial essay aims to show the main imaging findings in 47 coronary computed tomography scans acquired at a general hospital between January 2014 and June 2018. The most common findings were atheromatous plaques (in 87%) and stents (in 34%). There were also incidental findings, not directly related to coronary artery disease, such as pulmonary nodules and aortic stenosis.
Objective: Analyze the historical series of cases of Acute Myocardial Infarction (AMI) and the mortality rates related to the disease in the Pireneus region in Goiás, from 2010 to 2019, and identify the points of attention for patient care, comparing to the established criteria and parameters in Portaria N° 210, of June 15, 2004. Methods: This is an observational, quantitative, descriptive and exploratory study. Data were collected using the Sistema de Informações Hospitalares do SUS (SIH/SUS) and the Sistema de Informações de Óbito (SIM). The focus of the study was the population of the Pireneus health region, in Goiás, in the period from 2010 to 2019. A historical series and a retrospective longitudinal bibliographic research on patients diagnosed with AMI and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
