Cardiac sympathetic reserve and response to cardiac resynchronization therapy.
BACKGROUND The objective of the present study was to investigate the effect of cardiac resynchronization therapy (CRT) on cardiac autonomic function. METHODS AND RESULTS This prospective study included 45 consecutive patients with heart failure who received CRT devices with defibrillator and 20 age-matched, healthy control subjects. At baseline and 3 months and 6 months after CRT, we assessed...
متن کاملIncremental value of radial discoordination index for the prediction of response to cardiac resynchronization therapy.
AIMS Previous studies have identified four baseline characteristics associated with a favourable response to cardiac resynchronization therapy (CRT): female, non-ischaemic aetiology of heart failure, left bundle-branch block (LBBB), and QRS duration ≥150 ms. This study evaluated the incremental value of discoordination and dyssynchrony indices over these characteristics for the prediction of th...
متن کاملPrediction of cardiac resynchronization therapy response: value of calibrated integrated backscatter imaging.
BACKGROUND Left ventricular (LV) fibrosis is important for the response to cardiac resynchronization therapy (CRT). Calibrated integrated backscatter derived by 2D echocardiography quantifies myocardial ultrasound reflectivity, which may provide a surrogate of LV fibrosis. The aim of the study was first, to investigate the relation of myocardial ultrasound reflectivity assessed with calibrated ...
متن کاملCircumferential 2D-strain imaging for the prediction of long term response to cardiac resynchronization therapy
BACKGROUND Cardiac Resynchronization Therapy (CRT) leads to hemodynamic and clinical improvement in heart failure patients. The established methods to evaluate myocardial asynchrony analyze longitudinal and radial myocardial function. This study evaluates the new method of circumferential 2D-strain imaging in the prediction of the long-term response to CRT. METHODS AND RESULTS 38 heart failur...
متن کاملCardiac-resynchronization therapy.
Cardiac resynchronization therapy (CRT) addresses abnormal left ventricular (LV) activation that produces detrimental effects on cardiac systolic and diastolic function. CRT improves symptoms and ventricular performance, promotes reverse remodeling, and decreases mortality and hospitalization in patients with congestive heart failure (CHF). Atrial-synchronized biventricular stimulation reverses...
