Significats de viable myocardium en anglès

The main objective of the cardiological PET investigations was the exploration of viable myocardium.

Angiographical demonstration of coronary collateral circulation may suggest the presence of residual viable myocardium.

Combined use of the two techniques could improve viable myocardium detection in patients with acute MI.

The transition zone consisted of a mixed signal intensity, while the remote zone contained viable myocardium.

Conclusions: Sensitivity was higher while specificity was lower on detecting viable myocardium by DISA compared to LDDE.

The additional area depicted by the HASTE-TIRM sequence could represent functionally impaired but viable myocardium).

However, viable myocardium alone or mixed with scar was seen in 2 specimens from PVs with conduction block.

Histological analysis confirmed the continuity of viable myocardium transmurally throughout the length of the gap in each preparation.

This protection is associated with mitigation of myocyte apoptosis, translating into more viable myocardium and less ventricular dysfunction.

Reperfused viable myocardium exhibited residual glucose metabolism with FDG, whereas fatty acid oxidation remained impaired for a longer period.

Histopathology revealed increased areas of viable myocardium and vascular density in the EPO+GCSF therapy, compared to the control.

These results suggest that coronary collateral may contribute to minimizing the infarct area and to prediction of the presence of viable myocardium.

This study tests the hypothesis that increased levels of plasma lipids can accelerate accumulation of myocardial triacylglycerols in post-ischemic but viable myocardium.

Conceptually, replacement of akinetic scar tissue by viable myocardium and improvement of neovascularization should improve cardiac function and impede progressive left ventricular remodelling.

A new and exciting technique to detect viable myocardium is magnetic resonance imaging, which has been shown to have similar diagnostic accuracy as FDG-PET.

The techniques currently used to assess myocardial infarction are limited in their ability to determine the amount of viable myocardium after a temporary ischemic event.
