Late gadolinium enhancement was the strongest imaging predictor of adverse cardiovascular outcomes in patients with Fabry disease (HR 4.45; 95% CI 2.82-7.02).
Meta-Analysis (n=1,713)
Do echocardiography and CMR imaging parameters predict adverse clinical outcomes in patients with Fabry disease?
Several imaging parameters, particularly late gadolinium enhancement, are significant predictors of adverse clinical outcomes in patients with Fabry disease.
Effect estimate: HR 4.45 (95% CI 2.82-7.02)
Abstract Background Cardiac involvement represents the main cause of death in patients with Fabry disease (FD). Echocardiography and cardiovascular magnetic resonance (CMR) have an established diagnostic role, but their prognostic value remains unresolved. This systematic review and meta‐analysis sought to assess the prognostic implications of imaging parameters in FD. Methods PubMed, ClinicalTrials.gov , Embase, Cochrane Library and Web of Science databases were searched for studies from inception through 1 May 2024. Studies including FD patients undergoing baseline imaging assessment and clinical follow‐up were selected. Pre‐defined study outcomes were a cardiovascular endpoint and a composite clinical endpoint. The study protocol was registered in PROSPERO (ID CRD42022342394). Results Fourteen studies, including 1713 FD patients (44.7% males), were selected. At pooled analysis, late gadolinium enhancement (hazard ratio HR: 4.45; 95% CI: 2.82–7.02), left atrium volume indexed (HR: 1.02 per mL/m 2 ; 95% CI: 1.01–1.03), E/e′ (HR: 1.14 per unit increase; 95% CI: 1.08–1.21), left ventricular (LV) mass indexed (HR: 1.01 per mg/m 2 ; 95% CI: 1.00–1.02), maximum LV wall thickness (HR: 1.19 per mm, 95% CI: 1.04–1.36) and LV‐global longitudinal strain (HR: 1.20 per unit increase; 95% CI: 1.16–1.25) were significantly associated with the cardiovascular endpoint, whereas T1‐mapping and LV‐ejection fraction were not. T1‐mapping was associated with the composite endpoint (HR: 0.99 per msec increase; 95% CI: 0.98–1.00). Meta‐regression analysis did not show any significant interaction between each of the potential effect modifiers. Conclusions Several imaging parameters were significant predictors of adverse clinical outcomes in patients with FD. Late gadolinium enhancement showed the strongest association with adverse prognosis.
Stankowski et al. (Wed,) conducted a meta-analysis in Fabry disease (n=1,713). Imaging parameters (echocardiography and cardiovascular magnetic resonance) was evaluated on Cardiovascular endpoint (HR 4.45, 95% CI 2.82-7.02). Late gadolinium enhancement was the strongest imaging predictor of adverse cardiovascular outcomes in patients with Fabry disease (HR 4.45; 95% CI 2.82-7.02).
