Key result
Strict ECG evaluation of drug-induced QT/QTc prolongation is strongly recommended to prevent sudden cardiac death.
Why the study?
Drug-induced prolongation of the QT/QTc interval can cause ventricular tachyarrhythmia and sudden cardiac death, necessitating careful clinical evaluation and objective ECG assessment in drug development.
Highlights the importance of objective ECG evaluation for QT/QTc prolongation in the development of new drugs to prevent drug-induced long QT syndrome and sudden cardiac death.
Supports strict ECG evaluation in drug development to mitigate arrhythmia risk; leaves open prospective validation of protocols.
Prolongation of QT/QTc interval during medical treatment can occur not only with cardiovascular drugs but also with non-cardiovascular drugs. It may result in ventricular tachyarrhythmia, a high-risk condition which may trigger sudden cardiac death. Thus, to avoid drug-induced long QT syndrome and serious complications careful attention should be paid in the clinical setting. Moreover, in the last several years objective evaluation by strictly applying electrocardiogram (ECG) data has been strongly recommended for the development of all new drugs in discussions held at the International Conference on Harmonization (ICH). This recommendation has already been adopted in the USA and the EU and is expected to be announced shortly in our country. Not only the drugs but a variety of patient background factors may influence ECG parameters, especially the QT/QTc interval. It is necessary to introduce an appropriate study protocol that can evaluate the risk for QT/QTc prolongation related to the drug. Additionally, an adequate system to record, measure, and evaluate ECG with high objectivity must be applied to all clinical trials.
