Myocardial blood volume and the amount of viable myocardium early after mechanical reperfusion of acute myocardial infarction: prospective study using venous contrast echocardiography

摘要

Conclusions: Early after successful mechanical reperfusion of acute myocardial infarction, the magin- tude of capillary perfusion in the perfusion territory of an infarct related artery is correlated with the amount of viable myocardium. Quantitative venous contrast echocardiography can be used for accu- rate identification of viable myocardium. Background: Myocardial capillary perfusion is a prerequisite of myocellular viability after reperfusion Of acute myocardial infarction. It was hypothesised that the magnitude of myocardial capillary Perfusion, assessed by transmural signal intensity in venous contrast echocardiography as a corollary Of the blood volume of myocardial capillaries, and the amount of viable myocardium, represented by Differential levels contractile function two weeks after reperfusion, are correlated.
