AIM: Recently, digoxin use has been found to associate with higher mortality. Yet, potential mechanisms by which digoxin use increases mortality remain unclear. Increased arrhythmogenicity from digoxin use is one possibility. Thus, we aimed to evaluate the relation between digoxin and shock events in patients with implantable cardioverter defibrillators (ICDs). METHODS: We performed a retrospective chart review of all patients with ICDs and at least 1 device interrogation at our institution between January 1, 2012, and January 1, 2015...

Rationale: Lisdexamfetamine is a prodrug of D-amphetamine used for the treatment of attention-deficit/hyperactivity disorder (ADHD). Lisdexamfetamine is thought to have a prolonged pharmacokinetic profile compared with oral D-amphetamine, possibly associated with lower drug liking and a lower risk of oral misuse. However, differences in the pharmacokinetics and pharmacodynamics of lisdexamfetamine and D-amphetamine have not been directly compared. Methods: Equimolar doses of D-amphetamine (40 mg) and lisdexamfetamine (100 mg), and placebo were administered in 24 healthy subjects in a randomized, double-blind, placebo-controlled, cross-over study...

BACKGROUND: Tracheal extubation is almost always associated with increase in sympathoadrenal activity may result in hypertension, tachycardia, and arrhythmias. Attempts have been made to oppose the pressor response by the use of various drugs. Dexmedetomidine decreases norepinephrine which reduces the blood pressure and the heart rate (HR). We hypothesize that the infusion of dexmedetomidine may produce more stable hemodynamics during extubation as compared to boluses. MATERIALS AND METHODS: Ninety adult patients aged 18-65 years, the American Society of Anesthesiologists Grade I-II undergoing intracranial surgeries for various neurologic problem at All India Institute of Medical Sciences were enrolled in this randomized controlled trial...

INTRODUCTION: A heart rate higher than 90 beats/min indicates an unfavorable prognosis for patients with multiple organ dysfunction syndrome (MODS). We sought to investigate the effect of the pacemaker current (If) inhibitor ivabradine on heart rate, hemodynamics, and disease severity among patients with MODS. MATERIAL AND METHODS: In this prospective, controlled, randomized, open-label, two-arm phase II trial, seventy patients with MODS, a sinus rhythm of at least 90 beats/min, and contraindications to β-blocker therapy were randomly assigned to receive the standard treatment ± ivabradine (5 mg twice daily) for 96 h via the enteral route...

In addition to increasing sympathetic nervous activity, blood pressure, and cerebral blood flow (CBF), the cold pressor test (CPT) stimulates pain receptors, which may increase ventilation above metabolic demand; this response likely reduces the partial pressure of end-tidal carbon dioxide (PET CO2 ), and will attenuate elevations in CBF. We hypothesized: (1) CPT would elicit hyperventilation, effectively lowering PET CO2 ; (2) the CBF response will be elevated during an isocapnic (controlled PET CO2 ), compared to a poikilocapnic CPT (uncontrolled PET CO2 ); (3) In response to CPT, the common carotid artery (CCA) will vasodilatate, while the internal carotid artery (ICA) will remain unchanged to help regulate CBF...

OBJECTIVE: Mindfulness training has been shown to improve psychological well-being and physical health. One proposed pathway for the positive effects of mindfulness training is through the development of new emotion regulation strategies, such as the ability to experience emotions by observing and accepting them without judgment. Theoretically, this should facilitate recovery from negative emotional states; however, this has rarely been examined empirically. The goal of the current study was to determine whether mindfulness training is associated with more efficient emotional and cardiovascular recovery from induced negative affect...

OBJECTIVE: Black Americans (BAs) are at an elevated risk for morbidity and mortality in comparison to White Americans (WAs). Racial stressors are a common occurrence in American culture and is theorized to contribute to these disparities. When race-focused, stereotype threat (ST) is considered to be a factor that is detrimental to health in BAs; however few studies have directly investigated the impact of a ST manipulation on physiological function. Furthermore, it is proposed that racial stressors such as ST may have prolonged effects when more likely to perseverate (e...

Mineralocorticoid receptor antagonists (MRAs) constitute a beneficial therapy in chronic heart failure, but their use in the acute heart failure (AHF) setting remains rather unexplored. To assess the effect of MRAs administered during hospitalization on in-hospital outcomes of patients with AHF, we performed a post-hoc analysis of the Acute Heart Failure Global Registry of Standard Treatment (ALARM-HF). Patients of the original study cohort (n = 4953) were categorized according to in-hospital MRA treatment status as MRA-treated (n = 1439) and untreated (n = 3514) subjects...
