Pentamidine-induced long QT syndrome and block of hERG trafficking.
The diamidine pentamidine is used to treat leishmaniasis, trypanosomiasis, and Pneumocystis carinii pneumonia. Treatment may be accompanied by prolongation of the QT interval of the electrocardiogram and torsades de pointes tachycardias. Up to now, it has been thought that therapeutic compounds causing QT prolongation are associated with direct block of the cardiac potassium channel human ether...
متن کاملAn Integrative Data Science Pipeline to Identify Novel Drug Interactions that Prolong the QT Interval
INTRODUCTION Drug-induced prolongation of the QT interval on the electrocardiogram (long QT syndrome, LQTS) can lead to a potentially fatal ventricular arrhythmia known as torsades de pointes (TdP). Over 40 drugs with both cardiac and non-cardiac indications are associated with increased risk of TdP, but drug-drug interactions contributing to LQTS (QT-DDIs) remain poorly characterized. Traditio...
متن کاملEffect of epicardial or biventricular pacing to prolong QT interval and increase transmural dispersion of repolarization.
Prolong QT Interval and Increase Transmural Dispersion of Repolarization To the Editor: The recent article by Medina-Ravell et al1 addresses a potentially harmful effect of cardiac resynchronization therapy on ventricular repolarization. The authors found that single epicardial and biventricular pacing in patients with congestive heart failure increased the QT interval and the transmural disper...
متن کاملMolecular determinants of pentamidine-induced hERG trafficking inhibition.
Pentamidine is an antiprotozoal compound that clinically causes acquired long QT syndrome (acLQTS), which is associated with prolonged QT intervals, tachycardias, and sudden cardiac arrest. Pentamidine delays terminal repolarization in human heart by acutely blocking cardiac inward rectifier currents. At the same time, pentamidine reduces surface expression of the cardiac potassium channel I(Kr...
متن کاملDabigatran Does Not Prolong the QT Interval with Supratherapeutic Exposure: a Thorough QT Study in Healthy Subjects
BACKGROUND Dabigatran etexilate is a pro-drug of the oral reversible direct thrombin inhibitor dabigatran that interacts with the active site in the catalytic domain of the thrombin molecule. OBJECTIVE To assess the electrophysiological effects of therapeutic and supratherapeutic doses of dabigatran etexilate in healthy subjects, a thorough QT study was performed. METHODS In this single-cen...
