Why the study?
Patients with IBD have a higher risk of cardiovascular diseases due to chronic inflammation and treatment effects, but early cardiac dysfunction in childhood-onset IBD needed assessment using layer-specific strain analysis.
Does childhood-onset inflammatory bowel disease affect left ventricular function as measured by layer-specific strain analysis compared to healthy controls?
Does childhood-onset inflammatory bowel disease affect left ventricular function as measured by layer-specific strain analysis compared to healthy controls?
Childhood-onset inflammatory bowel disease is associated with early subclinical left ventricular dysfunction that can be detected using layer-specific strain echocardiography.
Childhood-onset IBD was associated with lower layer-specific GLS; leaves open whether strain monitoring improves outcomes.
BACKGROUND: Patients with inflammatory bowel disease (IBD) are at a higher risk of developing cardiovascular diseases than healthy individuals, owing to persistent chronic inflammation and treatment effects. This study aimed to assess left ventricular function in patients with childhood-onset IBD using layer-specific strain analysis and to identify early indicators of cardiac dysfunction in them. METHODS: A total of 47 patients with childhood-onset ulcerative colitis (UC), 20 patients with Crohn's disease (CD), and 75 age- and sex-matched healthy control subjects were included in this study. Conventional echocardiographic measurements of layer-specific (ie, endocardium, midmyocardium, and epicardium) global longitudinal strain and global circumferential strain (GCS) were evaluated in these participants. RESULTS: Layer-specific strain analysis showed that global longitudinal strain was lower in all layers for the UC (P < .001) and CD (P < .001) groups, regardless of the age at onset, but that GCS was only lower in the midmyocardial (P = .032) and epicardial (P = .018) layers in the CD group than in the control group. Although the mean left ventricular wall thickness was not significantly different among the groups, it was significantly correlated with the GCS of the endocardial layer in the CD group (ρ= -0.615; P = .004), suggesting that thickening of the left ventricular wall occurred as a compensatory mechanism to maintain the endocardial strain in the CD group layer. CONCLUSIONS: Children and young adults with childhood-onset IBD displayed decreased midmyocardial deformation. Layer-specific strain could also be useful to identify indicators of cardiac dysfunction in patients with IBD.
