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.

Background: The ECM (extracellular matrix) provides the microenvironmental niche sensed by resident vascular smooth muscle cells (VSMCs). Aging and disease are associated with dramatic changes in ECM composition and properties; however, their impact on the VSMC phenotype remains poorly studied.
Methods: Here, we describe a novel in vitro model system that utilizes endogenous ECM to study how modifications associated with age and metabolic disease impact the VSMC phenotype.

Type B aortic dissection (TBAD) represents a serious medical emergency with up to a 50% associated 5-year mortality caused by thoracic aorta, dissection-associated aneurysmal (DAA) degeneration, and rupture. Unfortunately, conventional size-related diagnostic methods cannot distinguish high-risk DAAs that benefit from surgical intervention from stable DAAs. Our goal is to use DAA stiffness measured with magnetic resonance elastography (MRE) as a biomarker to distinguish high-risk DAAs from stable DAAs.

Recent studies have attempted to characterize the layer-specific mechanical and microstructural properties of the aortic tissues in either normal or pathological state to understand its structural-mechanical property relationships. However, layer-specific tissue mechanics and compositions of normal and dissected ascending aortas have not been thoroughly compared with a statistical conclusion obtained. Eighteen ascending aortic specimens were harvested from 13 patients with type A aortic dissection and 5 donors without aortic diseases, with each specimen further excised to obtain three tissue samples including an intact wall, an intima-media layer and an adventitia layer.

Objective: Globally, one in four pregnant women is classified as overweight or obese, based on their prepregnancy body mass index (BMI). Obese pregnant women are at increased risk of adverse pregnancy outcomes and long-term cardiovascular disease that occurs earlier in life. This study aimed to assess maternal hemodynamic and vascular parameters at 35-37 weeks' gestation, to understand the alterations that may occur in association with increased maternal BMI and gestational weight gain, and to evaluate obesity-related pregnancy outcomes.

Disrupted feeding and fasting cycles as well as chronic high fat diet (HFD)-induced obesity are associated with cardiovascular disease risk factors. We designed studies that determined whether two weeks of time-restricted feeding (TRF) intervention in mice fed a chronic HFD would reduce cardiovascular disease risk factors. Mice were fed a normal diet (ND; 10% fat) ad libitum or HFD (45% fat) for 18 weeks ad libitum to establish diet-induced obesity.
