Background: Cardiac resynchronization therapy (CRT) has become an accepted method for treating refractory heart failure (HF). Arterial distensibility is an index of arterial stiffness and a surrogate marker for atherosclerosis. The present study aims to assess the acute effects of ventricular resynchronization therapy with biventricular stimulation on arterial distensibility, echocardiographic parameters and serum norepinephrine levels in patients with drug refractory HF.
