Chronic heart failure continues to impose a substantial health-care burden, despite recent
treatment advances. The key pathophysiological process that ultimately leads to chronic …

BACKGROUND: Cardiac resynchronization therapy (CRT) is effective in reducing clinical
events in systolic heart failure patients with a wide QRS. Previous retrospective studies …

The content of these European Society of Cardiology (ESC) Guidelines has been published

Background One variable that may influence cardiac resynchronization therapy response is
the programmed atrioventricular (AV) delay. The SmartDelay Determined AV Optimization: A …

Background—Cardiac resynchronization therapy (CRT) plus implantation of an implantable
cardioverter defibrillator (ICD) reduced the risk of death or heart failure event in patients with …

Background Acute studies have suggested that left ventricular pacing (LVP) may have
benefits over biventricular pacing (BVP). The adaptive cardiac resynchronization therapy …

Background: Cardiac resynchronization therapy (CRT) reduces morbidity and mortality in
patients with advanced symptoms of heart failure. Purpose: To assess the benefits and …

Background—Left ventricular (LV) pacing alone may theoretically avoid deleterious effects
of right ventricular pacing. Methods and Results—In a multicenter, double-blind, crossover …

Aims Few data are available on the extent and prognostic value of reverse left ventricular
remodelling (r-LVR) after ST-elevation acute myocardial infarction (STEMI). We sought to …

BACKGROUND: Biventricular (BiV) stimulation is the preferred means of delivering cardiac
resynchronization therapy (CRT), although left ventricular (LV)–only stimulation might be as …
