Clinical Implication of Mechanical Dyssynchrony in Heart Failure
Mechanical dyssynchrony is a common phenomenon in patients with congestive heart failure, which usually identified by noninvasive cardiac imaging tools such as echocardiography. It demonstrates electromechanical delay in some regions of the failing heart which in turn contributes to further impairment of cardiac function. The diagnostic, therapeutic and prognostic values of mechanical dyssynchr...
متن کاملClinical Assessment and Implication of Left Ventricular Mechanical Dyssynchrony in Patients with Heart Failure.
UNLABELLED There have been numerous studies focusing on the assessment of left ventricular mechanical dyssynchrony. These studies are diverse in their purposes, which include more effectively predicting the response to cardiac resynchronization therapy, improving the guidance of the left ventricular lead position, and better prediction of outcome in patients with heart failure. This article rev...
متن کاملElectrical and mechanical dyssynchrony for prediction of cardiac events in patients with systolic heart failure.
BACKGROUND Recent clinical trials have challenged the clinical applicability of mechanical dyssynchrony in predicting cardiac resynchronisation therapy response. OBJECTIVE To evaluate whether mechanical dyssynchrony has an additional benefit over QRS duration in predicting cardiac events in patients with systolic heart failure. METHODS A total 167 patients admitted to hospital with heart fa...
متن کاملQuantification of left ventricular mechanical dyssynchrony by conductance catheter in heart failure patients.
Mechanical dyssynchrony is an important codeterminant of cardiac dysfunction in heart failure. Treatment, either medical, surgical, or by pacing, may improve cardiac function partly by improving mechanical synchrony. Consequently, the quantification of ventricular mechanical (dys)synchrony may have important diagnostic and prognostic value and may help to determine optimal therapy. Therefore, w...
متن کاملMechanical dyssynchrony after myocardial infarction in patients with left ventricular dysfunction, heart failure, or both.
BACKGROUND Mechanical dyssynchrony is considered an independent predictor for adverse cardiovascular outcomes in patients with heart failure. However, its importance as a risk factor after myocardial infarction is not well defined. METHODS AND RESULTS We examined the influence of mechanical dyssynchrony on outcome in patients with left ventricular dysfunction, heart failure, or both after myo...
