Effect of dynamic myocardial dyssynchrony on mitral regurgitation during supine bicycle exercise stress echocardiography in patients with idiopathic dilated cardiomyopathy and 'narrow' QRS.
AIMS Cardiac resynchronization therapy (CRT) has become an attractive therapeutic option for patients with end-stage heart failure (HF). Currently, patients are selected for CRT on ECG and on echocardiographic criteria analysed at rest. Whether the physical effort may further increase myocardial dyssynchrony is not fully established. The aim of the study was to test by the use of Doppler myocar...
متن کاملCardiac Resynchronization Therapy Leads to Improvements in Handgrip Strength
BACKGROUND A reduction in skeletal muscle performance measured by handgrip strength is common in heart failure. No trial has investigated the role of cardiac resynchronization therapy, which leads to improvements in cardiac performance, on the function of skeletal muscle in patients with heart failure. METHODS Nineteen patients were recruited, 18 male, age 69 ± 8 years, New York Heart Associa...
متن کاملImpact of cardiac resynchronization therapy on inflammatory biomarkers and cardiac remodeling: The paradox of functional and echocardiographic response.
INTRODUCTION Response to cardiac resynchronization therapy (CRT) can currently be assessed by clinical or echocardiographic criteria, and there is no strong evidence supporting the use of one rather than the other. Reductions in B-type natriuretic peptide (BNP) and C-reactive protein (CRP) have been shown to be associated with CRT response. This study aims to assess variation in BNP and CRP six...
متن کاملThe MELD scoring system and the prediction of outcomes in heart failure patients: what we have learned from the hepatologists.
Heart failure remains a leading cause of morbidity and mortality, with increasing numbers of patients being affected annually. Developing models and approaches for predicting adverse outcomes and survival is of particular importance in determining when to initiate specific therapies, in particular those for advanced heart failure such as cardiac transplantation and mechanical circulatory suppor...
متن کاملCardiac-resynchronization therapy in heart failure with a narrow QRS complex.
BACKGROUND Indications for cardiac-resynchronization therapy (CRT) in patients with heart failure include a prolonged QRS interval (> or =120 msec), in addition to other functional criteria. Some patients with narrow QRS complexes have echocardiographic evidence of left ventricular mechanical dyssynchrony and may also benefit from CRT. METHODS We enrolled 172 patients who had a standard indic...
