Insights
Patients with coeliac disease (CD) show impaired aortic function, including reduced aortic strain and distensibility, and increased aortic stiffness. This suggests a higher risk of atherosclerosis and cardiovascular events in individuals with CD.
Area of Science:
- Cardiovascular Physiology
- Gastroenterology
- Immunology
Background:
- Coeliac disease (CD) is an autoimmune disorder affecting the small intestine.
- Aortic function, encompassing aortic stiffness index, strain, and distensibility, is a known predictor of atherosclerosis.
- The relationship between CD and cardiovascular health, specifically aortic function, requires further investigation.
Purpose of the Study:
- To investigate the association between key indicators of aortic function and coeliac disease.
- To determine if CD is linked to altered aortic stiffness, strain, or distensibility.
Main Methods:
- Echocardiography was used to assess aortic distensibility, strain, and stiffness index.
- Serological markers for autoimmune activity were measured in 36 CD patients and 35 controls.
- Statistical analysis was performed to identify correlations between CD and aortic function parameters.
Main Results:
- Patients with CD exhibited significantly lower aortic strain and distensibility compared to controls.
- A significantly higher aortic stiffness index was observed in CD patients.
- Coeliac disease was identified as an independent predictor of all measured aortic function parameters.
Conclusions:
- Deteriorated aortic function, indicative of subclinical atherosclerosis, was demonstrated in CD patients via echocardiography.
- Impaired aortic function in CD patients highlights a potential increased risk for cardiovascular events.
- Enhanced collaboration between cardiology and gastroenterology, along with increased awareness among healthcare providers and patients, is crucial for managing cardiovascular risk in CD.
Background And Aim:
We aimed to investigate the association between aortic function (aortic stiffness index, aortic strain, and aortic distensibility), which is a predictor of atherosclerosis, and coeliac disease (CD).
Methods:
Thirty-six patients with CD and 35 control subjects were included in the study. Serological screening was performed to determine the levels of auto-immune markers, including anti-gliadin immunoglobulin (Ig)A and IgG, and anti-tissue transglutaminase antibodies. Aortic distensibility, aortic strain, and aortic stiffness index were calculated using echocardiography.
Results:
Aortic strain and aortic distensibility were significantly lower in patients with CD than in control subjects (0.07 [0.03-0.14] vs. 0.09 [0.06-0.15], p < 0.001; 0.0036 ± 0.0012 vs. 0.0051 ± 0.0014, p < 0.001, respectively). However, the aortic stiffness index was significantly higher in patients with CD than in controls (1.14 [0.57-2.69] vs. 0.91 [0.59-1.92], p = 0.002). Coeliac disease was the only independent parameter that was correlated with aortic strain, aortic stiffness index, and aortic distensibility (b = -0.427, p < 0.001; b = 0.375, p = 0.003; b = -0.434, p < 0.001, respectively).
Conclusions:
In this study, we showed deteriorated aortic functions by echocardiography in CD patients, which predicted subclinical atherosclerosis. Because deteriorated aortic functions is a strong predictor of future cardiovascular events, close cooperation with cardiologists and gastroenterologists is needed in the management of CD patients, and increased awareness of ischaemic heart disease risk factors in these patients and healthcare providers is warranted.
