Long-term effectiveness of cardiac resynchronization therapy in patients with refractory heart failure and "narrow" QRS.
OBJECTIVES The aim of the study was to evaluate the effectiveness of cardiac resynchronization therapy (CRT) in patients with refractory heart failure (HF) and incomplete left bundle branch block ("narrow" QRS), together with echocardiographic evidence of interventricular and intraventricular asynchrony. BACKGROUND Cardiac resynchronization therapy has been proven effective in patients with H...
متن کاملActivity monitoring in heart failure patients with cardiac resynchronization therapy.
BACKGROUND Cardiac resynchronization therapy (CRT) improves functional capacity in heart failure patients. This study aimed to prospectively analyze long-term device-based monitoring of physical activity in patients undergoing CRT. METHODS AND RESULTS The Activity Log Index (ALI), calculated by CRT devices, represents the percentage of time when acceleration exceeds a threshold and monitors t...
متن کاملCardiac resynchronization therapy in heart failure patients with atrial fibrillation
Cardiac resynchronization therapy (CRT) is an important device-based, non-pharmacological approach that has shown, in large randomized trials, to improve left ventricular (LV) function and reduce both morbidity and mortality rates in selected patients affected by advanced heart failure (HF): New York Heart Association (NYHA) functional class III-IV, reduced LV systolic function with an ejection...
متن کاملCardiac resynchronization therapy in patients with heart failure: systematic review.
CONTEXT AND OBJECTIVE Cardiac resynchronization therapy (CRT) has emerged as the predominant electrical treatment strategy for patients on pharmacological therapy who present heart failure with wide QRS and low ejection fraction. The objective of this study was to investigate whether cardiac resynchronization therapy improved mortality and morbidity among patients with heart failure. METHODS ...
متن کاملClinical Effectiveness of Cardiac Resynchronization Therapy Versus Medical Therapy Alone Among Patients With Heart Failure
BACKGROUND Cardiac resynchronization therapy with defibrillator (CRT-D) reduces morbidity and mortality among selected patients with heart failure in clinical trials. The effectiveness of this therapy in clinical practice has not been well studied. METHODS AND RESULTS We compared a cohort of 4471 patients from the National Cardiovascular Data Registry's Implantable Cardioverter-Defibrillator ...
