TL;DR: MCE had a comparable accuracy and, as a bedside technique, may be an alternative tool in the acute phase of acute myocardial infarction as well as an alternative method to differentiate viable from infarcted tissue.

Abstract: The relative merits of myocardial contrast echocardiography (MCE) and magnetic resonance imaging (MRI) to predict myocardial function improvement after percutaneous coronary intervention have not been evaluated until now. We studied 35 consecutive patients with acute myocardial infarction who underwent percutaneous coronary intervention using MCE and MRI and first-pass imaging for evaluation of myocardial perfusion. Delayed-enhanced MRI was included as another method to differentiate viable from infarcted tissue. MCE was performed by power modulation and intravenous Sonovue. A 16-segment model of the left ventricle was used to analyze all myocardial contrast echocardiograms and magnetic resonance images. At 60 days of follow-up, MCE showed improvement of function in 115 of 192 (60%) dysfunctional segments. The sensitivity, specificity, and accuracy for the prediction of functional improvement were comparable among MCE (87%, 90%, and 88%), first-pass MRI (87%, 60%, and 79%), and delayed-enhancement MRI (75%, 100%, and 82%, respectively, all p = NS). In conclusion, MCE and MRI allowed for prediction of myocardial function improvement after percutaneous coronary intervention. MCE had a comparable accuracy and, as a bedside technique, may be an alternative tool in the acute phase of acute myocardial infarction.

TL;DR: The results show that CE-US and CE-MRI have good agreement in assessing inflammatory changes in knee OA, and an analgesic effect of icatibant could clearly be shown, especially for pain during activity in the high dose ic atibant group.

The clinical applications of myocardial contrast echocardiography
TL;DR: The detection of myocardial perfusion during echocardiographic examinations permits simultaneous assessment of global and regional myocardia structure, function, and perfusion, enabling the optimal non-invasive assessment of coronary artery disease.

TL;DR: EPAMINONDAS is a multicenter, prospective, double-blind, placebo-controlled, dose-finding study assessing intravenous moderate doses of human recombinant Epo (epoietin-α, 100 or 200 IU/kg/die) versus placebo, given on the first 3 days, in 102 patients with first ST-segment elevation myocardial infarction.

Usefulness of power Doppler contrast echocardiography to identify reperfusion after acute myocardial infarction
TL;DR: In this article, power Doppler imaging (MCE) was used to visualize myocardial reperfusion during intravenous contrast injection, which is a sensitive and specific method for the identification of myocardia reperfusing early after myocardious infarction.

Evolution of regional performance after an acute anterior myocardial infarction in humans using magnetic resonance tagging
TL;DR: Using magnetic resonance (MR) myocardial tagging, the fact that MR tagging can identify both regional deformation and loading permits us to differentiate between changes due to alterations in regional loading conditions and true changes in function.
