Abstract:
Aortic stiffness underlies systolic hypertension, promotes heart failure and is associated with increased cardiovascular morbidity and mortality. It is regarded as a primary driver of left ventricular hypertrophy and aortic aneurysms and is linked to the pathogenesis of cognitive impairment, stroke and renal failure. Like most cardiovascular traits, aortic stiffness is a complex trait and is moderately heritable, yet the precise molecular mechanisms that underpin the stiffening process remain poorly defined.

Age-related increases in arterial stiffness are mediated in part by mitochondrial dysfunction. Sirtuin 3 (SIRT3) is a mitochondrial NAD+-dependent deacetylase that regulates mitochondrial function. SIRT3 deficiency contributes to physiological dysfunction in a variety of pathological conditions. Here, we tested the hypothesis that age-associated arterial stiffness, assessed by aortic pulse wave velocity (PWV), would be accompanied with decreased renal and aortic SIRT3 expression and activity due to decreased NAD+ levels. We further tested whether boosting NAD+ concentration with nicotinamide r

For more than half a century cardiovascular disease has been the leading cause of death in the United States.  Aging, hypertension, and obesity are major risk factors for cardiovascular disease and clearly associated with arterial stiffness.  Arterial stiffness generates higher afterloads and diminishes coronary perfusion thereby causing ventricular hypertrophy and ischemia.  Importantly, arterial stiffness is an independent predictor of cardiovascular disease risk and all-cause mortality.   Current strategies such as inhibition of angiotensin II or angiotensin converting enzyme, reduction of

Older age is a primary risk factor for the development of cardiovascular disease in part through the stiffening of the large cardiothoracic elastic arteries (e.g., aorta, carotid arteries). Aging is also associated with reduced cognitive function, cerebrovascular reactivity and brain white matter integrity, but whether these changes in brain structure and function are associated with age-related large artery stiffness remains unclear. In contrast, older adults who have high aerobic fitness demonstrate attenuated large artery stiffness and better cognitive performance compared to their sedentar

Motivation A close association exists between hypertension and arterial stiffness. Whether the increased arterial stiffness seen in hypertensives are due to structural or functional adaptations in the vasculature is uncertain. Hypertension is more common in blacks and they have an increased arterial stiffness and higer stroke prevalence than white populations. Arterial stiffening, or a loss of arterial distensibility, increases the risk for cardiovascular events, including stroke and heart failure, as it increases the afterload on the heart, as well as creating a higher pulsatile load on the m

Vascular remodelling plays an important role in the adaptation of the athlete to increased exercise duration and intensity. Endurance exercise improves endothelium-dependent flow-mediated vasodilation and leads to increases in conduit artery lumen diameter after regular exercise, typically in the trained limb. These changes result in a reduced vascular stiffnes. On the contrary strength training (e.g. for weight-lifting) produces increased vascular stiffness and enlarged central vessels (e.g. aortic root diameters), while the diameters of peripheral vessels are unchanged.

Abstract:
Hypoxic pulmonary hypertension (HPH) leads to stiffening of large pulmonary arteries, which affects right ventricular afterload. We hypothesized that vascular collagen accumulation is the major cause of large pulmonary artery (PA) stiffening in HPH. We tested this hypothesis with transgenic mice that produce collagen type I resistant to degradation (Col1a1R/R) and wild type littermate controls (Col1a1+/+) exposed to hypoxia and allowed to recover. Pressure-diameter testing on left PAs demonstrated that stiffness in control mice increased with hypoxia and decreased with recovery (p < 0.05).

Pulmonary hypertension (PH) is a complex disorder that manifests as abnormally high blood pressure in the vasculature of the lungs.

Recent evidence has shown that conduit PA stiffness is a strong predictor of mortality in pulmonary arterial hypertension5,6.

Abstract:
Pulmonary artery hypertension (PAH) is a female dominant disease (the female-to-male ratio is 4:1), characterized by small distal pulmonary arterial narrowing and large proximal arterial stiffening, which increase right ventricle (RV) afterload and ultimately lead to RV failure [1,2]. Our recent studies have shown that collagen accumulation induced by chronic hypoxia increases the stiffness of the large extralobar pulmonary arteries (PAs) [3], and affects pulmonary vascular impedance (PVZ) [4]. The role of collagen in the female predominance in developing PAH has not been explored to date.
