Left Ventricular Dyssynchrony: Effect of Age, Ejection Fraction, Mass and Cardiovascular Disease

چکیده
acquired using TPM in basal, midventricular, and apical short axis slices. B: Data for each subject were mapped onto an AHA 16-segment model. For each segment, the velocity time courses were used to derive systolic (TTPSys) and diastolic (TTPDia) times-to-peak velocity as illustrated for radial and long-axis velocities. C: Systolic and diastolic dyssynchrony was assessed by calculating the standard deviation (SD) of radial and long-axis TTP over all 16 segments.

Intraventricular dyssynchrony in light chain amyloidosis: a new mechanism of systolic dysfunction assessed by 3-dimensional echocardiography
BACKGROUND Light chain amyloidosis (AL) is a rare but often fatal disease due to intractable heart failure. Amyloid deposition leads to diastolic dysfunction and often preserved ejection fraction. We hypothesize that AL is associated with regional systolic dyssynchrony. The aim is to compare left ventricular (LV) regional synchrony in AL subjects versus healthy controls using 16-segment dyssync...
متن کاملLeft ventricular dyssynchrony in patients with heart failure and preserved ejection fraction.
AIMS Mechanical dyssynchrony has been postulated to play a pathophysiologic role in heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS We quantified left ventricular (LV) systolic dyssynchrony in 130 HFpEF patients with NYHA class II-IV symptoms, ejection fraction (EF) ≥45%, and NT-proBNP levels >400 pg/mL enrolled in the PARAMOUNT trial, and compared them to 40 healt...
متن کاملAssociation of age with left ventricular volumes, ejection fraction and concentricity: the Framingham heart study
Background Left ventricular (LV) parameters may vary with aging, but concomitant disease can obscure relationships between age and LV size, mass and function. CMR provides reproducible measures of LV volumes, mass, and ejection fraction (EF), but manual analyses are time consuming. Automated border detection (ABD) methods may decrease analytical burden. We sought to examine the effect of greate...
متن کاملThe effect of eight weeks of moderate-intensity endurance training on myocardial capillary density, ejection fraction and left ventricular shortening fraction in male rats with myocardial infarction
Background and objective: Vascular obstruction and impaired blood flow and oxygen delivery cause a myocardial infarction and limit a personchr('39')s function. Therefore, finding a way to create new arteries and replace blocked arteries has always been of interest to researchers, including exercise physiologists. Therefore, this study was conducted to evaluate the effect of eight weeks of moder...
متن کاملVentricular dyssynchrony and increased BNP levels in right ventricular apical pacing.
BACKGROUND Long-term right ventricular apical pacing can cause ventricular dyssynchrony and, secondarily, neurohumoral alterations and increase in cardiac morbimortality. OBJECTIVE To analyze ventricular dyssynchrony and its effects on BNP levels in patients with pacemakers and long-term right ventricular (RV) apex pacing. METHODS Cross-sectional study of 85 patients with single or dual cha...
