Cardiac resynchronization results in significant clinical improvement in patients who have moderate-to-severe heart failure and an intraventricular conduction delay.Abstract:
Background Previous studies have suggested that cardiac resynchronization achieved through atrial-synchronized biventricular pacing produces clinical benefits in patients with heart failure who have an intraventricular conduction delay. We conducted a double-blind trial to evaluate this therapeutic approach. Methods Four hundred fifty-three patients with moderate-to-severe symptoms of heart failure associated with an ejection fraction of 35 percent or less and a QRS interval of 130 msec or more were randomly assigned to a cardiac-resynchronization group (228 patients) or to a control group (225 patients) for six months, while conventional therapy for heart failure was maintained. The primary end points were the New York Heart Association functional class, quality of life, and the distance walked in six minutes. Results As compared with the control group, patients assigned to cardiac resynchronization experienced an improvement in the distance walked in six minutes (+39 vs. +10 m, P=0.005), functional clas...read more

TL;DR: Recent surveys of Guidelines and Expert Consensus Documents published in peer-reviewed journals between 1985 and 1998 have shown that methodological standards were not complied with in the vast majority of cases.

TL;DR: Cardiac resynchronization has been shown to reduce symptoms and improve left ventricular function in patients with heart failure due to systolic dysfunction and cardiac dyssynchrony.

TL;DR: In this paper, the authors tested the hypothesis that prophylactic cardiac-resynchronization therapy in the form of biventricular stimulation with a pacemaker with or without a defibrillator would reduce the risk of death and hospitalization among patients with advanced chronic heart failure and intraventricular conduction delays.

Absence of effect on exercise capacity of 12-weeks treatment with ramipril in patients with moderate congestive heart failure. Ramipril Study Group.
TL;DR: A significant decrease in blood pressure and rate-pressure product at rest and at end of exercise was obtained by ramipril as compared with placebo, andSignificantly fewer patients deteriorated in NYHA class from baseline to 12 weeks of Ramipril treatment compared to placebo.
