The long QT syndrome [PDF]

, 2010
peer reviewedThe congenital long QT syndrome (LQTS) is a hereditary cardiac disease characterized by a prolongation of the QT interval > 440 ms at rest ECG associated with a high risk of ventricular arrhythmias (torsade de pointe).

Never Out of the Woods: Onset of Events in Long QT Syndrome Late in Life Provoked by Atrial Arrhythmias

Indian Pacing and Electrophysiology Journal, 2014
The assessment of risk in the asymptomatic patient with long QT syndrome can often be a challenging task, particularly when the available evidence is limited to relatively small retrospective registries, not to mention the need to consider the effect of ...

Immune checkpoint inhibitor‐induced arrhythmias: Mechanistic insights from clinical and preclinical studies

British Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitors (ICIs) have transformed cancer therapy, but their efficacy continues to be limited by immune‐related adverse events. Among these, ICI‐induced cardiac arrhythmias are increasingly recognised as a major adverse reaction, encompassing a broad spectrum of clinical phenotypes, including conduction blocks, atrial fibrillation and

Arrhythmias associated with immune checkpoint inhibitor therapy—A clinical perspective

British Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitors (ICIs) have transformed cancer therapy but are associated with a growing spectrum of cardiovascular immune‐related adverse events. Among these, arrhythmias represent a rare yet potentially life‐threatening complication. ICI‐induced arrhythmias encompass a wide clinical spectrum, including atrial arrhythmias, conduction ...

Clinical and genetic characteristics of long QT syndrome

, 2007
Long QT syndrome (LQTS) is an arrhythmogenic ion channel disorder characterized by severely abnormal ventricular repolarization, which results in prolongation of the electrocardiographic QT interval.

Risk of cardiac events in patients with asthma and long-QT syndrome treated with beta(2) agonists. [PDF]

, 2008
The clinical course and risk factors associated with beta(2)-agonist therapy for asthma have not been investigated previously in patients with the long-QT syndrome (LQTS).

Microminipig, a Non-rodent Experimental Animal Optimized for Life Science Research: In Vivo Proarrhythmia Models of Drug-Induced Long QT Syndrome: Development of Chronic Atrioventricular Block Model of Microminipig

Journal of Pharmacological Sciences, 2011
A new in vivo proarrhythmia model of drug-induced long QT syndrome was developed using the Microminipig, an incredibly small minipig established by Fuji Micra Inc. (Shizuoka).

Signal detection and characterisation of a novel drug–drug interaction between methadone and a synthetic cannabinoid receptor agonist

British Journal of Pharmacology, EarlyView.
Background and Purpose Little is known about how synthetic cannabinoid receptor agonist (SCRA) co‐use with other psychoactive substances may exacerbate risk of death. This study aimed to characterise the polypharmacy of deaths where SCRAs were detected at post‐mortem, investigate the cardiotoxicity of SCRAs and probe their inhibition of human ether‐a ...

Quizartinib Resistance Mutations and Treatment Outcomes in Relapsed or Refractory FLT3‐ITD–Positive AML

Cancer Science, EarlyView.
ABSTRACT Quizartinib is a FMS‐like tyrosine kinase 3 (FLT3) inhibitor indicated for FLT3 internal tandem duplication (FLT3‐ITD)–positive acute myeloid leukemia (AML). We aimed to evaluate quizartinib resistance mechanisms, in addition to efficacy and safety outcomes, in patients with relapsed or refractory FLT3‐ITD–positive AML.

Acute Hypokalemia May Not Be an Effective Way to Sensitize the In Situ Canine Heart for Sparfloxacin-Induced Long QT Syndrome

Journal of Pharmacological Sciences, 2006
.: Extents of the sparfloxacin (3 – 10 mg/kg, i.v.)-induced QT interval prolongation under normokalemic and hypokalemic conditions were assessed in halothane-anesthetized beagle dogs (n = 5).
