Heart failure–induced cardiovascular morbidity and mortality constitute a major health
problem worldwide and result from diverse pathogeneses, including coronary artery …

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

Background—This study aimed to determine whether QRS morphology identifies patients
who benefit from cardiac resynchronization therapy with a defibrillator (CRT-D) and whether …

Background—Clinical trials of cardiac resynchronization therapy (CRT) have enrolled a
select group of patients, with few patients in subgroups such as right bundle-branch block …

522 AURICCHIO A et al. it is a common clinical observation that repeated short exacerbation
periods are followed by relatively long periods of clinical stability during which …

Aims In CARE‐HF, cardiac resynchronization therapy (CRT) lowered morbidity and mortality
in patients with moderate to severe heart failure. We examined whether baseline and follow …

Objectives This study sought to evaluate the effectiveness of His-optimized cardiac
resynchronization therapy (HOT-CRT) for reducing left ventricular activation time (LVAT) …

Patients with heart failure and decreased function frequently develop discoordinate
contraction because of electric activation delay. Often termed dyssynchrony, this further …

Background Multiple studies have sought to determine variables associated with improved
“response” to cardiac resynchronization therapy (CRT). Such variables, however, are often …

Aims Because benefits of cardiac resynchronization therapy (CRT) appear to be less
favourable in non-left bundle branch block (LBBB) patients, this prospective longitudinal …
