Strain-Encoded Magnetic Resonance Imaging in Acute Myocardial Infarction

2014-08-27 03:27:41 | BioPortfolio


The aim of the study was therefore to evaluate whether myocardial deformation imaging performed by SENC allows for quantification of regional left ventricular function and is related to transmurality states of infarcted tissue in patients with acute myocardial infarction (AMI).


CMR was performed in 38 consecutive patients with AMI 3±1 days after successful reperfusion using a clinical 1.5 Tesla MR-scanner. Ten healthy volunteers served as controls. SENC is a technique that directly measures peak circumferential strain from long-axis views and peak longitudinal strain from short axis views. Measurements were obtained for each segment in a modified 17 segment model. Wall motion and infarcted tissue were evaluated semi-quantitatively from SSFP cine sequences and contrast-enhanced-MR-images and were then related to myocardial strain. Comparison of peak circumferential strain assessed by SENC and MR-tagging was performed.

Medical and Biotech [MESH] Definitions

MYOCARDIAL INFARCTION in which the anterior wall of the heart is involved. Anterior wall myocardial infarction is often caused by occlusion of the left anterior descending coronary artery. It can be categorized as anteroseptal or anterolateral wall myocardial infarction.

A myocardial infarction that does not produce elevations in the ST segments of the ELECTROCARDIOGRAM. ST segment elevation of the ECG is often used in determining the treatment protocol (see also ST Elevation Myocardial Infarction).

Laceration or tearing of cardiac tissues appearing after MYOCARDIAL INFARCTION.

A clinical syndrome defined by MYOCARDIAL ISCHEMIA symptoms; persistent elevation in the ST segments of the ELECTROCARDIOGRAM; and release of BIOMARKERS of myocardial NECROSIS (e.g., elevated TROPONIN levels). ST segment elevation in the ECG is often used in determining the treatment protocol (see also NON-ST ELEVATION MYOCARDIAL INFARCTION).

An episode of MYOCARDIAL ISCHEMIA that generally lasts longer than a transient anginal episode but that does not usually result in MYOCARDIAL INFARCTION.
