Metabolic syndrome in adults with congenital heart disease and increased intima-media thickness.

AIMS: Age-related cardiovascular diseases are a relevant risk in the aging population of adults with congenital heart diseases (ACHD). Risk factors such as the metabolic syndrome (MetS) impact the risk of increased carotid intima-media thickness (cIMT) and thereby long-term cardiovascular diseases. The aim of the study was to assess MetS in ACHD and outline a possible association to cIMT. METHODS AND RESULTS: In total, 512 ACHD (43.0 ± 9.6 years, 48.9% female) were screened for MetS by the standards of the International Diabetes Federation, and their cIMT by ultrasound from January 2017 to June 2019. MetS was prevalent in 72 (14.1%) of the ACHD population (34 female, 15.5%). Regarding severity class, patients with simple forms of CHD had a MetS prevalence of 11.8%, moderate 16.7%, and severe 13.8%. ACHD with MetS had significantly increased cIMT compared to ACHD without MetS (ACHD with MetS: 0.587 ± 0.079 mm, ACHD without MetS: 0.560 ± 0.087 mm, mean difference: 0.028 mm, P = .013). Such a difference in vascular structure corresponds to roughly five years of normal vascular aging of the vessels. CONCLUSION: ACHD with MetS have a thicker cIMT compared to ACHD without MetS. Screening for MetS and targeting risk factors in ACHD might help to prevent structural alterations of the vessels at an early stage.      «
