Advancing the diagnosis of cardiac electrophysiological disorders in diabetes: integrating clinical, imaging, and molecular insights

Diabetes mellitus is a systemic metabolic disorder associated with an increased risk of cardiac electrophysiological abnormalities, including atrial and ventricular arrhythmias, conduction disturbances, and autonomic dysfunction. These complications contribute substantially to morbidity and mortality but are frequently underrecognized due to limitations of conventional diagnostic approaches that rely primarily on surface electrocardiography and intermittent monitoring. Growing evidence suggests that electrophysiological instability in diabetes arises from a complex interaction of metabolic dysregulation, microvascular impairment, inflammation, and molecular alterations that are not fully captured by traditional electrical assessments alone. Recent advances in cardiovascular imaging, molecular diagnostics, and artificial intelligence–driven analytics provide new opportunities to enhance the detection, risk stratification, and characterization of diabetic cardiac electrophysiological disorders. This Perspective discusses the evolving clinical spectrum of electrophysiological abnormalities in diabetes, highlights the shortcomings of existing diagnostic paradigms, and explores emerging innovations that integrate clinical assessment with advanced imaging and molecular insights. We propose an integrative diagnostic framework that leverages multimodal data and digital health technologies to enable earlier identification of high-risk individuals and support precision cardiology approaches. Advancing such integrated diagnostic strategies may improve clinical decision-making, facilitate personalized management, and ultimately reduce the burden of cardiac electrophysiological complications in people with diabetes.
