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...
متن کاملTransmural 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...
متن کاملAssessment of myocardial viability: using coronary pressure and flow after acute myocardial infarction.
Assessment of myocardial viability has been a challenge for revascularisation therapeutics in determining the effectiveness of an intervention and patient prognosis. In most cases, the current standard for viability is the recovery of function measured by left ventricular (LV) wall motion and the metabolic activity measured by positron emission tomography (PET) with the uptake of the metabolic ...
متن کاملAssessment of Myocardial Reperfusion by Intravenous Myocardial Contrast Echocardiography and Coronary Flow Reserve After Primary Percutaneous Transluminal Coronary Angiography in Patients With Acute Myocardial Infarction
Background—This study investigated whether the extent of perfusion defect determined by intravenous myocardial contrast echocardiography (MCE) in patients with acute myocardial infarction (AMI) treated by primary percutaneous transluminal coronary angioplasty (PTCA) relates to coronary flow reserve (CRF) for assessment of myocardial reperfusion and is predictive for left ventricular recovery. M...
متن کاملMyocardial strain analysis in acute coronary occlusion: a tool to assess myocardial viability and reperfusion.
BACKGROUND This study proposes 2 new echocardiographic indices with potential application in acute coronary artery occlusion to differentiate between viable and necrotic myocardium and to identify reperfusion. We investigated whether the ratio between systolic lengthening and combined late and postsystolic shortening (L-S ratio) could identify viable myocardium and whether systolic myocardial c...
