Radiomic analysis to predict arrhythmias in athletes by echocardiography: Artificial intelligence vs. formal methods

Year: 2025

Type: article

Abstract: The diagnosis and management of premature ventricular beats (PVBs) in athletes remain challenging due to the potential for underlying cardiac pathology. While the electrocardiogram is essential for detecting electrical abnormalities, echocardiography is crucial for evaluating structural heart disease. This study explores the use of radiomics analysis applied to apical 4-chamber echocardiography to automatically and preemptively identify PVB risk, better characterize athlete cardiac remodeling, and enable early detection of pathological changes.We evaluated and compared the limitations and potential of Artificial Intelligence (AI) and Formal Methods (FM) for this task. Using data from 723 athletes, we processed echocardiography videos and extracted over 100 features per athlete to develop robust classifiers.Our findings demonstrate that radiomics can power automated decision-support systems for diagnosis. While AI-based models offer powerful predictive capabilities, FM presents a compelling, mathematically rigorous, and explainable alternative. Both modalities are useful for the early detection of structural substrates underlying PVBs. The collaboration between physicians and computer scientists is crucial to unlocking new frontiers in radiomics and advancing personalized medicine. • While ECG detects premature ventricular beats (PVB), the apical 4-chamber echocardiography can early identify PVB in athletes. • We challenged Artificial Intelligence algorithms and Formal Methods to understand their limitations and potential. • Collecting data from 723 athletes, echocardiography videos were pre-processed and more than 100 features were extracted. • To the best of our knowledge, this study is the first to detect PVB in athletes using Radiomics. • It also represents the first application of Formal Methods in sports medicine and cardiology. • Key points: early detection of cardiac abnormalities, overcoming ECG limits, faster and safer arrhythmia risk prediction with a virtual second opinion.
