Pharmacogenetics of Drug-Induced QT Interval Prolongation: An Update
A prolonged QT interval is an important risk factor for ventricular arrhythmias and sudden cardiac death. QT prolongation can be caused by drugs. There are multiple risk factors for drug-induced QT prolongation, including genetic variation. QT prolongation is one of the most common reasons for withdrawal of drugs from the market, despite the fact that these drugs may be beneficial for certain p...
متن کاملDrug induced QT prolongation.
The drug-induced QT prolongation predisposes to development of torsades de pointes (TdP) ventricular tachycardia and sudden death. The association between specific drug and development of TdP is difficult to document, therefore, QT prolongation is considered as a surrogate marker of the proarrhythmia risk. Most of the drugs prolong QT interval usually by blocking the potassium IKr current or al...

Copyright © 2004 Massachusetts Medical Society. n the past decade, the single most common cause of the withdrawal or restriction of the use of drugs that have already been marketed has been the prolongation of the QT interval associated with polymorphic ventricular tachycardia, or torsade de pointes (Fig. 1), which can be fatal. 1 Nine structurally unrelated drugs...

متن کاملDrug-induced QT prolongation journal article
Background: Although QT prolongation is associated with increased risk of torsade de pointes (TdP), the precise relationship is not well defined. Aim: To evaluate the performance of a QT nomogram in assessing the risk of TdP from QT– RR combinations. Design: Systematic review. Methods: We systematically searched MEDLINE/ EMBASE for cases of drug-induced TdP. Controls were patients taking non-ca...
