Cardiac resynchronization therapy in chronic heart failure.
Cardiac resynchronisation therapy (CRT) has emerged as a treatment option for patients with severe, drug-refractory heart failure and signs of intraventricular dyssynchrony. In clinical trials CRT reduced the overall mortality, improved symptoms, exercise tolerance, and left ventricular function, as compared with optimised medical therapy alone. One of the challenging fields in patient selectio...
متن کاملLong-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 کاملCardiac resynchronization therapy in heart failure.
Cardiac resynchronization therapy (CRT) is a new therapeutic approach for a selected group of patients with symptomatic heart failure (NYHA functional class III-IV) despite optimal medical therapy, due to dilated cardiomyopathy of any etiology (left ventricular ejection fraction < or = 35% and left ventricular end-diastolic diameter > or = 55 mm), who present with electromechanical dyssynchrony...
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: an update.
Heart failure continues to be a major public health problem with high morbidity and mortality rates, despite the advances in medical treatment. Advanced heart failure patients have severe persistent symptoms and a poor quality of life. Cardiac resynchronization therapy (CRT), an invasive therapy which involves synchronized pacing of both right and left ventricles, improves ventricular conductio...
