INTRODUCTION Red-cell distribution width (RDW) has been identified as a novel prognostic marker in heart failure patients. However, evidence is limited for its predictive value in the setting of patients hospitalized with decompensated heart failure (DHF) and no data are available for African Americans (AA). METHODS AND RESULTS Data that included baseline(More)
Tolvaptan is the first FDA-approved oral V(2) receptor antagonist for the treatment of euvolemic and hypervolemic hyponatremia, in patients with conditions associated with free water excess such as heart failure, cirrhosis, and the syndrome of inappropriate antidiuretic hormone secretion. Tolvaptan inhibits the binding of arginine vasopressin to the V(2)(More)
BACKGROUND Left-sided native valve infective endocarditis (LNVIE) can result in mitral (MP) and aortic (AP) valve perforation, the prognostic significance of which remains poorly defined. HYPOTHESIS Valvular perforation is associated with worse outcomes. METHODS Retrospective review of patients with LNVIE during 1998-2005 was performed to examine(More)
Hypertensive emergencies (HEs) are frequently accompanied with the release of cardiac troponin I (cTnI); however, determinants and clinical significance of cTnI elevation are largely unknown. A retrospective analysis was performed on patients (n = 567) with a diagnosis of HE admitted to two tertiary care centers that primarily serve an inner-city(More)
Lixivaptan (VPA-985), being developed by Biogen Idec and Cardiokine, under license from Wyeth (now part of Pfizer), is a non-peptide, selective vasopressin V2 receptor antagonist for the potential oral treatment of hyponatremia associated with heart failure. Arginine vasopressin, the native V2 receptor ligand, stimulates water reabsorption via activation of(More)
Hyponatremia is the most common electrolyte abnormality in hospitalized patients and is associated with increased morbidity and mortality. The recognition of the central role that arginin vasopressin plays in the pathogenesis of hyponatremia and the discovery that its actions are mediated by stimulation of V(1A) and V(2) receptors have led to the(More)
INTRODUCTION Lixivaptan is a selective vasopressin type 2 (V2) receptor antagonist that induces aquaresis, the electrolytes sparing excretion of water. Its ability to correct hyponatremia has been demonstrated in experimental animal studies as well as in clinical trials in humans. Recently, three Phase III, double-blind, randomized, placebo-controlled(More)
INTRODUCTION Hypervolemia and hyponatremia are common features in heart failure and have been associated with increased morbidity and mortality. Stimulation of arginine vasopressin (AVP) plays an important role in the development of both hypervolemia and hyponatremia. Lixivaptan is a selective vasopressin type 2 (V(2)) receptor antagonist that has been(More)
Existing metrics for grading mitral regurgitation (MR) are limited and fraught with high interobserver variability. We developed and evaluated a Doppler-based, semiquantitative novel index (Mitral Regurgitation Severity Index [MRSI]) of MR severity. In a total of 125 patients (70 in the derivation cohort and 55 in the validation cohort), MRSI was calculated(More)
Eustachian valve endocarditis caused by Actinomyces species is extremely rare. A literature review revealed only one reported case-caused by Actinomyces israelii in an intravenous drug abuser. Our patient, a 30-year-old woman who at first appeared to be in good health, presented with fever, a large mobile mass on the eustachian valve, and extensive(More)
