Cardiac involvement in Wilson’s disease: A retrospective cohort study
Background and objectives: Wilson’s disease (WD) is an inherited disorder with perturbations in copper metabolism and can cause multiorgan damage. This study aims to explore cardiac findings mainly based on electrocardiography (ECG) in WD patients.
Methods: The authors retrospectively enrolled adult patients who were diagnosed with WD between January 2011 and December 2020. Demographic and clinical data were collected and re-evaluated.
Results: A total of 126 patients were included. There were 71 men and 55 women. The mean age was 27.2 years. 99 had hepatic presentation as the initial symptom and 27 had neuropsychiatric presentation as the initial symptom. 37 patients (29.4%) had cardiac manifestations. Of these patients, 9 presented apparent cardiac symptoms (3 with discontinuous chest tightness, 3 with dizziness, 2 with palpitation and 1 with atypical chest pain) and 28 had asymptomatic ECG abnormalities. Among the 9 patients, 4 had second- or third-degree atrioventricular block, 3 had ST-segment change and 2 had ventricular tachycardia. ECG abnormalities in the 28 patients included increase in the width of the QRS complex in 8, atrial premature beats in 8, T-wave inversion in 5, P-wave inversion in 2, sinus bradycardia in 2, ST-segment change in 2, and coexistence of sinus bradycardia and T-wave inversion in 1. No statistical difference (p = 0.32) existed in the occurrence of ECG abnormalities between patients with hepatic presentation (27/99) and those with neuropsychiatric presentation (10/27).
Conclusion: Cardiac involvement is not rare in adult patients with Wilson’s disease. The authors suggest that cardiac evaluation should be routinely performed in the population.
