Among athletes with ventricular repolarization abnormalities and normal echocardiography, 52.8% were diagnosed with heart disease over 7.3 years, with resting VRA persistence linked to diagnosis (p=0.
Does the persistence of ventricular repolarization abnormalities predict future cardiovascular diagnoses in athletes with normal baseline echocardiography?
In athletes with ventricular repolarization abnormalities and normal baseline echocardiography, prolonged surveillance is warranted as over half eventually receive a structural cardiovascular diagnosis, particularly those with persistent resting abnormalities.
Absolute Event Rate: 0% vs 0%
Background/Objectives: Ventricular repolarization abnormalities (VRA) represent a grey area in athlete screening: some patterns are physiological, while others are precursors to heart disease. Objective: to clarify the natural history of VRA and the associated factors of structural diagnosis. Methods: Retrospective observational single-center study of athletes with resting or stress VRA at the first evaluation, with normal echocardiography; minimum follow-up of 2 years. Clinical data, resting and stress ECG, echocardiography, and selective advanced imaging throughout follow-up were collected. Primary outcome: cardiovascular diagnosis at follow-up; time-to-event analysis and associations between ECG characteristics and diagnosis. Results: Fifty-three athletes (mean age 22.2 ± 9.2 years; 92.5% male) were included; 60.4% had resting VRA, and 100% had exercise-induced VRA at baseline. Over 7.3 ± 4.5 years, 28/53 (52.8%) received a diagnosis; median time-to-detection was 7.0 years (95% CI 6.0–not reached); RMST10 was 6.7 years (95% CI 5.7–7.7). Diagnoses included hypertrophic cardiomyopathy (24.5%), non-ischaemic left-ventricular scar (11.3%), myocardial bridging (7.5%), hypertensive remodelling (5.7%), coronary anomaly (1.9%), and ventricular pre-excitation (1.9%). Persistence of resting VRA from baseline to follow-up was more frequent in athletes with a final diagnosis (p = 0.01), whereas topography and exercise-induced abnormalities did not discriminate groups. Advanced imaging contributed substantially to case ascertainment. No major adverse cardiovascular events have been identified throughout follow-up. Conclusions: In athletes with screening-detected VRA and normal echocardiography, persistence of resting VRA was associated with higher detection of a cardiovascular diagnosis, while exercise-induced changes alone show limited diagnostic yield. The long median time-to-detection supports prolonged, pre-planned surveillance, with priority for advanced imaging in profiles with persistent abnormalities. These findings align with a risk-adapted, personalized management strategy in sports cardiology.
