Analysis of Left Ventricular Changes After Acute Myocardial Infarction Using Transthoracic Real-Time Three-Dimensional Echocardiography

Abstract

LVESVI assessed by 3-D echocardiography was the most predictive parameter indicating favorable LV remodeling after AMI. LV shape on contraction changed from elliptical shape to more globular in the adverse remodeling process after AMI.

3D Echo Pilot Study of Geometric Left Ventricular Changes after Acute Myocardial Infarction

“…No association has been detected between the index of ventricular dyssynchrony (which could represent the left intraventricular electromechanical decoupling) and the left ventricular remodeling. However, it has been verified the association between the three-dimensional sphericity index and the LVR, in a similar fashion in two previous studies with 19 and 33 patients affected by AMI 2,15 . In the study with 33 patients, it has been demonstrated that values above 0.25 for the three-dimensional sphericity index would present a sensibility of 100%, a specificity of 90%, a positive predictive value of 87%, and a negative predictive value of 100%, for the forecast of RVE 2 .…”

“…The three-dimensional echocardiography also provides for the analysis of the geometric modification of the left ventricle through the gauging of the three-dimensional sphericity index (3D SI) 2,15 . This new index relates the ventricular volume to the hypothetical left ventricular volume should the LV present a spherical shape.…”

“…This new index relates the ventricular volume to the hypothetical left ventricular volume should the LV present a spherical shape. A number of studies in the literature have related this new index of ventricular geometric analysis to the left ventricular remodeling after myocardial infarction 2,15 .…”

Characteristics of risk factors in young and middle-aged patients with first hemispheric ischemic stroke

“…2). Надо отметить, что фракция выброса менее 55% указыва-ет на снижение компенсаторных возможностей мио карда и может рассматриваться как одно из про-явлений его структурной перестройки [27]. Различ-ные нарушения ритма сердца выявлены у каждого больного старшей группы, в то время как в 1-й груп-пе они отмечены в 1 / 3 случаев (см.…”

Cardiac dyssynchrony

“…Yang et al [42] also investigated 30 consecutive patients who presented with an acute MI. They excluded 6 patients because of poor images, 3 patients who were lost to follow-up, and 2 patients who died during the index admission.…”
