Combined assessment of microvascular integrity and contractile reserve improves differentiation of stunning and necrosis after acute anterior wall myocardial infarction.

OBJECTIVES We sought to determine the relative accuracy of myocardial contrast echocardiography (MCE) and low-dose dobutamine echocardiography (LDDE) in predicting recovery of left ventricular (LV) function in patients with a recent anterior wall myocardial infarction (MI). BACKGROUND Left ventricular dysfunction after acute MI may be secondary to myocardial stunning or necrosis. Myocardial c...

Early changes in myocardial perfusion patterns after myocardial infarction: relation with contractile reserve and functional recovery.

OBJECTIVES The purpose of this study was to assess early temporal changes in myocardial perfusion pattern by myocardial contrast echocardiography (MCE) and their relation to myocardial viability in patients with reperfused acute myocardial infarction (AMI). BACKGROUND Myocardial contrast echocardiography no-reflow is associated with poor contractile recovery after AMI. However, little is know...

Transmural contractile reserve after reperfused myocardial infarction in dogs.

OBJECTIVES The goal of this study was to characterize detailed transmural left ventricular (LV) function at rest and during dobutamine stimulation in subendocardial and transmural experimental infarcts. BACKGROUND The relation between segmental LV function and the transmural extent of myocardial necrosis is complex. However, its detailed understanding is crucial for the diagnosis of myocardia...

Predicting Myocardial Functional Recovery After Acute Myocardial Infarction: Relationship Between Myocardial Strain and Coronary Flow Reserve

BACKGROUND AND OBJECTIVES The purpose of this study was to evaluate the relationship between myocardial strain and coronary flow reserve (CFR) in the prediction of myocardial functional recovery after acute myocardial infarction (AMI). SUBJECTS AND METHODS Consecutive patients with anterior ST elevation AMI were analyzed. Left ventricular (LV) strain, determined by 2-dimensional speckle track...

Impact of microvascular integrity and local viability on left ventricular remodelling after reperfused acute myocardial infarction.

OBJECTIVE To assess left ventricular remodelling in patients with reperfused acute myocardial infarction and to study its relation to microvascular damage. PATIENTS 25 patients successfully treated by primary percutaneous coronary angioplasty for acute myocardial infarction. SETTING University hospital METHODS Indexed end diastolic (EDVi) and end systolic (ESVi) volumes were assessed on a...
