Usefulness of myocardial circunferential strain in acute myocardial infarction for prediction of contractile function recovery: a MRI myocardial tagging study
نویسندگان
چکیده
Background In patients (p) with acute myocardial infarction (AMI), quantitation of myocardial regional function may be useful to differentiate between stunned and necrotic myocardium and to predict ventricular function recovery during follow-up. Different parameters exist to evaluate regional myocardial function such as circunferential /radial strain and displacement. The purpose of this study is to determine the most useful parameter for prediction of contractile function recovery obtained from tagged MRI.

Myocardial ischemia (MI) resulting in infarction is an important cause of mortality and morbidity worldwide. Acute ischaemia rapidly impairs myocardial contractile function. Myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. Hibernation is now thought to be...

Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...

Background: It is assumed giving oxygen to patients with acute myocardial infraction may increase the oxygenation of the ischemic tissue; however, the usefulness of oxygen in these patients has become a challenging topic. Thus, the present study aimed to determine the effect of oxygen inhalation on cardiac biomarkers in patients with acute myocardial infarction. Methods: This randomized cli...
