Arterial stiffness (AS) has a detrimental effect on cardiovascular system particularly on left ventricle (LV). The aim of the study was to evaluate the impact of AS on LV functions in patients with rheumatoid arthritis (RA). Forty patients with RA and 25 age-sex matched control subjects (mean age 48.5 ± 6.3 vs. 45.1 ± 6.9 years, respectively, p = 0.06) were enrolled in study. AS was assessed by carotid-femoral pulse wave velocity (CF-PWV) and heart rate corrected augmentation index (AIx@75) measured by applanation tonometry (SphygmoCor). LV function was evaluated using tissue Doppler-derived myocardial performance index (MPI) from lateral mitral annulus. CF-PWV (28.3 ± 10.3 vs. 21.8 ± 9.3 m/s, p = 0.03), AIx@75 (10.2 ± 2.3 vs. 9.2 ± 1, %, p = 0.01) and MPI (0.46 ± 0.12 vs. 0.36 ± 0.1, p < 0.001) were significantly higher in patients with RA than in controls. LV MPI was found to be significantly positive correlated with CF-PWV, AIx@75, and ESR (r = 0.360, p = 0.005; r = 0.334, p = 0.009; r = 0.293, p = 0.023, respectively). Arterial stiffness parameters including CF-PWV and AIx@75 are associated with subclinical left ventricular dysfunction in patients with RA.

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.

Aims: Aortic wall stiffening in ascending thoracic aortic aneurysm (aTAA) is common. However, the spatial and temporal relationships between stiffness, aortic size, and growth in aTAA remain unclear.
Methods And Results: In this single-centre retrospective study, we utilized vascular deformation mapping to extract multi-directional aortic motion, aortic distensibility, and aortic growth in a multi-planar fashion from multi-phasic ECG-gated computed tomography angiograms.

Background: Obesity and metabolic syndrome (MS) accelerate arterial stiffening, increasing cardiovascular (CV) risk after transplant. BMI is limited by inability to differentiate muscle, fat mass, and fat distribution patterns. The aim of this study was to identify the best anthropometric measure to detect arterial stiffness as assessed by pulse wave velocity (PWV) in a racially diverse pediatric transplant population.

AC is significantly influenced by arterial wall structure and vasomotion, and it markedly influences cardiac load. A new method, based on a two-element Windkessel model, has been recently proposed for estimating AC as the ratio of the time constant T of the diastolic blood pressure decay and peripheral vascular resistance derived from clinically available stroke volume measurements and selected peripheral blood pressure parameters which are less prone to peripheral distortions.

The vascular endothelium and its endothelial glycocalyx contribute to the protection of the endothelial cells from exposure to high levels of sodium and help these structures maintain normal function by regulating vascular permeability due to its buffering effect. The endothelial glycocalyx has negative surface charges that bind sodium and limit sodium entry into cells and the interstitial space. High sodium levels can disrupt this barrier and allow the movement of sodium into cells and extravascular fluid.
