Abstract
The corrected QT (QTc) interval is a critical marker for assessing proarrhythmic potential in drug development, while the corrected JT (JTc) interval provides specific insight into ventricular repolarization. This study quantitatively analyzed the relationships of QTc and JTc intervals with age and sex utilizing a large real-world dataset of hospital-based controls and moxifloxacin-treated patients. This retrospective study analyzed 1,039,550 electrocardiograms and associated clinical data extracted from a previously constructed electrocardiogram database, categorizing cases as hospital-based controls (n = 119,882) or moxifloxacin-treated (n = 1586) based on predefined criteria. We observed a general trend of QTc and JTc interval prolongation with age in both groups, with moxifloxacin-treated cases showing longer QTc and JTc intervals than hospital-based controls. Multiple linear regression analysis indicated that in hospital-based controls, QTc and JTc intervals increased with age, with males exhibiting shorter intervals than females. Meanwhile, in moxifloxacin-treated cases, QTc and JTc intervals showed similar age-dependent increases, although no significant sex differences were observed in the QTc interval. Therefore, this study quantified the effects of age and sex on QTc and JTc intervals in hospital-based controls and highlighted similar age-related trends in moxifloxacin-treated cases, underscoring the relevance of age and sex as key factors in interpreting QTc and JTc intervals across diverse clinical contexts.
期刊介绍：
Clinical and Translational Science (CTS), an official journal of the American Society for Clinical Pharmacology and Therapeutics, highlights original translational medicine research that helps bridge laboratory discoveries with the diagnosis and treatment of human disease. Translational medicine is a multi-faceted discipline with a focus on translational therapeutics. In a broad sense, translational medicine bridges across the discovery, development, regulation, and utilization spectrum. Research may appear as Full Articles, Brief Reports, Commentaries, Phase Forwards (clinical trials), Reviews, or Tutorials. CTS also includes invited didactic content that covers the connections between clinical pharmacology and translational medicine. Best-in-class methodologies and best practices are also welcomed as Tutorials. These additional features provide context for research articles and facilitate understanding for a wide array of individuals interested in clinical and translational science. CTS welcomes high quality, scientifically sound, original manuscripts focused on clinical pharmacology and translational science, including animal, in vitro, in silico, and clinical studies supporting the breadth of drug discovery, development, regulation and clinical use of both traditional drugs and innovative modalities.
