Principle component analysis of myocardial strain to quantify left ventricular dyssynchrony
Background Cardiac resynchronization therapy (CRT) is effective for selected heart failure (HF) patients, but is associated with a 30-40% nonresponse rate. Identification of CRT responders may be improved with myocardial strain imaging. The circumferential uniformity ratio estimate (CURE ) measures mechanical dyssynchrony by Fourier series fitting of myocardial strains over space, but requires ...
متن کاملImpact of Phase Analysis of Gated SPECT to Assessment of Left Ventricular Mechanical Dyssynchrony in Diabetic Patients with Normal MPI
Objective: Diabetes mellitus is an important cause of heart failure deployment of left ventricular mechanical dyssynchrony. Nuclear cardiology phase analysis is an accurate, repeatable and reproducible modality for measurement LV dyssynchrony .The aim of study was assessment of phase analysis parameter including Standard deviation (SD) and band width (BW) in diabetic patient with normal MPI com...
متن کامل[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 کاملLeft Ventricular Dyssynchrony After Acute Myocardial Infarction is a Powerful Indicator of Left Ventricular Remodeling
BACKGROUND AND OBJECTIVES Left ventricular (LV) remodeling (LVR) after an acute myocardial infarction (AMI) has important clinical implications. We have investigated the prognostic relevance of ventricular systolic dyssnchrony as an indicator of LVR after an AMI. SUBJECTS AND METHODS We enrolled 92 patients (males, 72.8%; mean age, 61.0+/-13.0 years) with an AMI who underwent successful percu...
متن کاملReal-time three-dimensional echocardiography: a novel technique to quantify global left ventricular mechanical dyssynchrony.
BACKGROUND Left ventricular (LV) mechanical dyssynchrony (LVMD) has emerged as a therapeutic target using cardiac resynchronization therapy (CRT) in selected patients with chronic heart failure. Current methods used to evaluate LVMD are technically difficult and do not assess LVMD of the whole LV simultaneously. We developed and validated real-time 3D echocardiography (RT3DE) as a novel method ...
