AIMS High-sensitivity cardiac troponin I (cTnI) assays hold promise in detecting the transition from hypertrophy to heart failure in aortic stenosis. We sought to investigate the mechanism for troponin release in patients with aortic stenosis and whether plasma cTnI concentrations are associated with long-term outcome. METHODS AND RESULTS Plasma cTnI(More)
OBJECTIVE To describe basic nonsuicidal self-injury (NSSI) characteristics and to explore sex differences. METHODS A random sample from 8 universities were invited to participate in a Web-based survey in 2006-2007; 38.9% (n = 14,372) participated. Analysis assessed sex differences in NSSI prevalence, practices, severity, perceived dependency, and(More)
PURPOSE To compare the efficacy of dolasetron and ondansetron in controlling nausea and vomiting in the first 24 hours; to evaluate the efficacy when dexamethasone is added to either drug in the first 24 hours; and to extend these comparisons over 7 days in patients receiving moderately emetogenic chemotherapy. PATIENTS AND METHODS This was a multicenter,(More)
Background—The Fontan procedure is a successful palliation for children with single-ventricle physiology; however, many will eventually require heart transplantation. The purpose of this study was to determine risk factors for death awaiting transplantation and to examine results after transplantation in Fontan patients. Methods and Results—A retrospective,(More)
OBJECTIVES Cardiac magnetic resonance (CMR) was used to investigate the extracellular compartment and myocardial fibrosis in patients with aortic stenosis, as well as their association with other measures of left ventricular decompensation and mortality. BACKGROUND Progressive myocardial fibrosis drives the transition from hypertrophy to heart failure in(More)
BACKGROUND 18F-Sodium fluoride (18F-NaF) and 18F-fluorodeoxyglucose (18F-FDG) are promising novel biomarkers of disease activity in aortic stenosis. We compared 18F-NaF and 18F-FDG uptake with histological characterization of the aortic valve and assessed whether they predicted disease progression. METHODS AND RESULTS Thirty patients with aortic stenosis(More)
BACKGROUND Dolasetron mesylate is a selective 5-HT3 receptor antagonist under investigation as an antiemetic in children. Published studies indicate that its antiemetic activity results from the active metabolite (MDL 74,156), which is produced within 10 minutes of administration of dolasetron mesylate. METHODS The pharmacokinetics of MDL 74,156 and the(More)
Sustained-release diltiazem, 120 and 180 mg twice daily, was assessed in a multicenter, double-blind, randomized, placebo-controlled trial in 65 stable angina patients with exercise-induced ST depression. Exercise testing was performed 12 +/- 1 hours after the last dose at the end of each of the 3 treatment weeks. Both dose levels of drug reduced(More)
BACKGROUND 5-HT3 antagonists are effective in reducing the acute nausea and vomiting caused by cancer chemotherapy. However, it is not clear whether continuing these agents beyond twenty four hours is useful in controlling emesis on days two to seven after chemotherapy. PATIENTS AND METHODS Four hundred seven patients receiving moderately emetogenic(More)
BACKGROUND Silent myocardial ischemia is an adverse prognostic marker in patients with coronary disease; however, controlled data on the effect of treatment are sparse and contradictory, and the relations among the occurrence of ST segment depression, drug efficacy, and heart rate are unclear. METHODS AND RESULTS Sixty patients with stable coronary artery(More)
