BACKGROUND We 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. METHODS A total of 1520 patients who(More)
BACKGROUND The mortality rate among patients with coronary artery disease, abnormal ventricular function, and unsustained ventricular tachycardia is high. The usefulness of electrophysiologic testing for risk stratification in these patients is unclear. METHODS We performed electrophysiologic testing in patients who had coronary artery disease, a left(More)
A large multicentre study on the short and long term clinical and developmental outcome of infants randomised to different diets is being undertaken. This report represents an interim analysis of the early postnatal growth performance of an unselected population of 194 preterm infants (gestation, mean (SD) 31 . 0 (2 . 9) weeks; birthweight, mean (SD) 1364(More)
OBJECTIVE To characterize the feasibility and safety of a wireless networked system incorporating physiologic assessments and direct confirmation of digital tablet ingestions in ambulatory patients with schizophrenia or bipolar disorder. METHOD In this 4-week observational study conducted between May 2010 and May 2011 at 2 US academic clinical study(More)
Fifteen patients aged 59.3 +/- 11.5 years (mean +/- standard deviation [SD]) had recurrent symptomatic ventricular tachycardia (VT) refractory to at least 2 conventional antiarrhythmic drugs. All patients had organic heart disease; 4 had an acute myocardial infarction. The mean ejection fraction was 0.30 +/- 0.09. TWelve patients had overt congestive heart(More)
OBJECTIVE ANTHEM-HF evaluated a novel autonomic regulation therapy (ART) via either left or right vagus nerve stimulation (VNS) in patients with heart failure (HF) and reduced ejection fraction (HFrEF). METHODS AND RESULTS Sixty subjects (New York Heart Association [NYHA] functional class II-III, left ventricular ejection fraction (LVEF) ≤ 40%, left(More)
BACKGROUND This open-label single-arm exploratory study evaluated the accuracy of the Ingestible Sensor System (ISS), a novel technology for directly assessing the ingestion of oral medications and treatment adherence. METHODS ISS consists of an ingestible event marker (IEM), a microsensor that becomes activated in gastric fluid, and an adhesive personal(More)
Twenty-four patients, mean age 42 years, with idiopathic dilated cardiomyopathy (DC) and no history of symptomatic ventricular arrhythmias underwent right ventricular programmed stimulation with up to 3 extrastimuli. Ventricular tachycardia (VT) was induced in 8 patients and ventricular fibrillation (VF) in 2. The VT was unimorphic in 2 and polymorphic in(More)
Electrophysiologic and hemodynamic studies were performed before and after intravenous infusion of a new antiarrhythmic agent, propafenone, in 28 patients with recurrent ventricular tachycardia. Propafenone was given at a loading dose of 2 mg/kg in all patients. Subsequently, group A, the first 14 patients, received 1 mg/min and group B, the second 14(More)
BACKGROUND Aldosterone blockade is recommended for patients with congestive heart failure after acute myocardial infarction complicated by left ventricular systolic dysfunction; however, the perceived risk of hyperkalemia may limit implementation of this therapeutic approach. This subanalysis examined the relationship between eplerenone, serum potassium(More)
