BACKGROUND: Depression is a relapsing and remitting disease. Prior studies on the association between depressive symptoms and incident cardiovascular disease (CVD) have been limited by single measurements, and few if any have examined both incident coronary heart disease and stroke in a large biracial national cohort. We aimed to assess whether time-dependent depressive symptoms conferred increased risk of incident CVD. METHODS AND RESULTS: Between 2003 to 2007, 22 666 black and white participants (aged ≥45 years) without baseline CVD in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study were recruited...

OBJECTIVE: Corrected QT (QTc) interval prolongation is often associated with use of first-generation antipsychotics (FGAs). However, other factors require appropriate consideration, including age and gender, the role of other known medications associated with QTc prolongation, and severe comorbid conditions, such as co-occurring alcohol abuse/dependence. We aimed to study potential mediating roles of different, related, candidate variables on QTc. METHODS: We capitalized on data from a large (N = 2366), cross-sectional, national survey, the STAR Network QTc study, using a representative sample of people taking FGAs, and recruited from mental health services across Italy...

INTRODUCTION AND AIMS: Drug induced QT prolongation occurs in patients with substance use disorders from prescription medications that prolong the QT, such as methadone. Knowing the prevalence of QT prolongation in this population is important for prescribers. This study aimed to investigate the prevalence of QT prolongation in patients with current substance use disorders. DESIGN AND METHODS: We undertook a retrospective review of electrocardiograms (ECG) from patients with substance use disorders from an urban general hospital with a large drug and alcohol service and toxicology unit...

BACKGROUND: Nonsense and frameshift mutations are common in congenital long QT syndrome type 2 (LQT2). We previously demonstrated that hERG nonsense mutations cause degradation of mutant mRNA by nonsense-mediated mRNA decay (NMD) and are associated with mild clinical phenotypes. The impact of NMD on the expression of hERG frameshift mutations and their phenotypic severity is not clear. OBJECTIVE: The purpose of this study was to examine the role of NMD in the pathogenesis of a hERG frameshift mutation, P926AfsX14, identified in a large LQT2 kindred and characterize genotype-phenotype correlations...

OBJECTIVES: We evaluated the association between dietary fish intake and several cardiac electrocardiographic parameters in humans relevant to arrhythmic risk. BACKGROUND: Fish consumption may reduce the incidence of sudden death and atrial fibrillation, possibly related to anti-arrhythmic effects. METHODS: In a population-based study of 5,096 men and women, we evaluated cross-sectional associations between usual dietary fish intake and electrocardiographic measures of heart rate, atrioventricular conduction (PR interval), ventricular repolarization (QT interval), and ventricular conduction (QRS interval)...

BACKGROUND: Antipsychotic drugs have been associated with prolongation of the QTc interval on the electrocardiogram, and QTc prolongation is, in turn, associated with an increased risk of cardiac arrhythmias and sudden death. Antipsychotic polypharmacy has been implicated in reduced survival, possibly secondary to cardiotoxic effects of antipsychotic medication. Abnormalities of glucose homeostasis, which may be more common in individuals with major mood disorders and schizophrenia, also affect the QTc interval...

UNLABELLED: Droperidol (DROP) is used in the emergency department (ED) for sedation, analgesia, and its antiemetic effect. Its ED safety profile has not yet been reported in patients (pts). OBJECTIVES: To document the use of DROP in high-risk pts (those with head injury, alcohol or cocaine intoxication, and/or remote or recent seizures), and to determine the number of serious and minor adverse events (AEs)-seizures, hypotension, extrapyramidal side effects (EPSEs)-after DROP...

OBJECTIVE: To report acute and mid-term electrocardiographic changes in patients with hypertrophic obstructive cardiomyopathy (HOCM) after alcohol ablation of the first large septal branch of the left anterior descending coronary artery; and to relate electrocardiographic data with the left ventricular outflow tract pressure gradients. PATIENTS: Nine consecutive symptomatic patients with HOCM (mean (SD) age 45 (12) years). METHODS: Analysis of baseline and post-procedure ECGs and 24 hour ambulatory monitoring (up to six months)...

Prolonged Q-T interval predicts severe arrhythmias and sudden death, and has been shown to occur in alcoholic liver disease and cirrhotic patients who are candidates for liver transplantation. This study first evaluated the prevalence of prolonged Q-T interval in a large population of unselected patients with cirrhosis, and assessed the relationship between abnormal Q-T, etiology, and severity of liver disease and mortality of patients. Possible causes of Q-T abnormality were also explored. Ninety-four patients with cirrhosis without overt heart disease and 37 control subjects with mild chronic active hepatitis were enrolled...
