Longitudinal Changes in Left Ventricular Blood Flow Kinetic Energy After Myocardial Infarction: Predictive Relevance for Cardiac Remodeling
نویسندگان
چکیده
Shows representative kinetic energy curves throughout the cardiac cycle of 2 separate patients, acquired at (12 months [V3]). The left panel shows a patient with preserved ejection fraction (pEF), while on right reduced (rEF). flow vectors peak-systole, PeakE-wave and PeakA-wave indexed for EDV each is shown underneath. rEF has higher systolic KEiEDV, lower KEiEDV KEiEDV. by Hadar Ben-Arzi et al.

[Cardiac dyssynchrony correlates with left ventricular remodeling after myocardial Infarction].
BACKGROUND Cardiac dyssynchrony is common in advanced heart failure (HF), but the changes in cardiac synchrony after myocardial infarction (MI) have not been adequately descríbed. AIM To study the relationship between cardiac synchrony and left ventricular remodeling after acute myocardial infarction. MATERIAL AND METHODS Forty nine patients aged 59+/-10 years (77% men) with a first episode...
متن کامل[Left ventricular remodeling after myocardial infarction].
Left ventricular remodeling describes a number of geometric and structural changes that the left ventricle undergoes after myocardial infarction. Briefly, it comprises expansion of the infarct and dilatation of the healthy left ventricular segments. Its severity is related to the infarct size. These changes in ventricular geometry, in particular the dilatation, influence the long-term incidence...
متن کاملLeft Ventricular Remodeling After Myocardial Infarction
Left ventricular remodeling is the process by which ventricular size, shape, and function are regulated by mechanical, neurohormonal, and genetic factors.1,2 Remodeling may be physiological and adaptive during normal growth or pathological due to myocardial infarction, cardiomyopathy, hypertension, or valvular heart disease (Figure 1). This article will review postinfarction remodeling, pathoph...
متن کاملLeft ventricular remodeling and ventricular arrhythmias after myocardial infarction.
BACKGROUND The relation between left ventricular (LV) remodeling and ventricular arrhythmias after myocardial infarction is poorly documented. We investigated the relations between LV size, hypertrophy, and function and ventricular arrhythmias in 263 patients from the Survival and Ventricular Enlargement (SAVE) study, using quantitative 2D echocardiography and ambulatory ECG monitoring after my...
متن کاملCyclosporin A in left ventricular remodeling after myocardial infarction.
Recent studies suggest that an increase in apoptosis within the myocardium may be a contributing factor for the progression of late adverse left ventricular (LV) remodeling following myocardial infarction (MI). Given that apoptosis is often triggered by induction of the mitochondrial permeability transition (MPT) pore, the goal of this study was to evaluate the therapeutic efficacy of cyclospor...
