Early Vascular Ageing – A Concept in Development
European Endocrinology, 2015
Cardiovascular disease (CVD) is a prevalent condition in the elderly, often associated with metabolic disturbance and type 2 diabetes. For a number of years, research dedicated to understand atherosclerosis dominated, and for many good reasons, this pathophysiological process being proximal to the CVD events. In recent years, research has been devoted to an earlier stage of vascular pathology named arteriosclerosis (arterial stiffness) and the new concept of early vascular ageing (EVA), developed by a group of mostly European researchers. This overview describes recent developments in research dedicated to EVA and new emerging aspects found in studies of families at high cardiovascular risk. There are new aspects related to genetics, telomere biology and the role of gut microbiota. However, there is still no unifying definition available of EVA and no direct treatment, but rather only recommendations for conventional cardiovascular risk factor control. New interventions are being de...
Early vascular aging syndrome: background and proposed definitions
Clinical Investigation, 2011
Vascular aging is a process linked to arterial stiffness and remodeling, as well as increased pulse wave velocity (PWV). Other aspects involve structural changes in the vascular tree that might have been influenced by detrimental factors in early life, such as impaired fetal growth or preterm birth, especially in combination with a rapid postnatal catch-up growth. Based on data from several European populations, normal reference values for PWV in defined age groups were published in 2010. Thus, outliers from the normal range can be defined and thus labeled with early vascular aging (EVA), as arterial stiffness is a major marker of EVA. Another approach to define EVA is to describe the component of PWV that cannot be explained by conventional cardiovascular risk factors alone. New therapies are emerging for treatment of EVA, beyond traditional risk factor control. One option could be the breaking up of glycation linkages in arterial tissue, or the use of new antidiabetes drugs with vascular actions, such as incretin analogues or DPP-4 inhibitors, for cardiovascular protection.
Short telomere length is associated with arterial aging in patients with type 2 diabetes mellitus
Endocrine Connections, 2015
It is known that glucose disturbances contribute to micro- and macrovascular complications and vascular aging. Telomere length is considered to be a cellular aging biomarker. It is important to determine the telomere length role in vascular structural and functional changes in patients with diabetes mellitus. We conducted a cross-sectional observational study in a high-risk population from Moscow, Russia. The study included 50 patients with diabetes and without clinical cardiovascular disease and 49 control group participants. Glucose metabolism assessment tests, measuring intima–media complex thickness and determining the presence of atherosclerotic plaques, pulse wave velocity measurement, and telomere length measurement were administered to all participants. Vascular changes were more dramatic in patients with diabetes than in the control group, and the telomeres were shorter in patients with diabetes. Significant differences were found in the vascular wall condition among diabet...
Early Vascular Ageing (EVA): Definitions and clinical applicability
Current hypertension reviews, 2017
Arterial stiffness has been accumulating evidence as an intermediate cardiovascular endpoint. It has been established as an independent risk marker for cardiovascular disease, and reflects the dissociation between chronologic and biologic age of large arteries - attributing earlier the risk that a normal vascular ageing process had installed to occur several years later. The construct of Early Vascular Ageing (EVA) is developed to establish primordial prevention, identifying individuals whose ageing path has been accelerated either by inherent features, interaction with the environment or arterial exposure to several types of insults that evolve to medial layer morphological changes. Understanding the pathophysiology of vascular ageing, its consequences and therapeutic opportunities is therefore an advantage that could be translated in time of prevention and survival free of cardiovascular disease. As the EVA construct is advancing, new features appear as interesting to better trans...
The Gut Microbiota and Vascular Aging: A State-of-the-Art and Systematic Review of the Literature
Journal of Clinical Medicine
The gut microbiota is a critical regulator of human physiology, deleterious changes to its composition and function (dysbiosis) have been linked to the development and progression of cardiovascular diseases. Vascular ageing (VA) is a process of progressive stiffening of the arterial tree associated with arterial wall remodeling, which can precede hypertension and organ damage, and is associated with cardiovascular risk. Arterial stiffness has become the preferred marker of VA. In our systematic review, we found an association between gut microbiota composition and arterial stiffness, with two patterns, in most animal and human studies: a direct correlation between arterial stiffness and abundances of bacteria associated with altered gut permeability and inflammation; an inverse relationship between arterial stiffness, microbiota diversity, and abundances of bacteria associated with most fit microbiota composition. Interventional studies were able to show a stable link between microb...
Clinical Interventions in Aging
The true onset of atherosclerosis remains one of the biggest challenges for cardiologists. Is atheroma plaque development considered the earliest step of vascular aging? If so, when it starts? Before or after birth? If it starts before birth or early during childhood, it seems that Thomas Sydenham was right: "A man is as old as his arteries." Except disorganization of elastic fibers, less is known about the morphology of vascular aging and also about the molecular events influencing the age of arteries, arterial stiffness, and their role in the appearance of future complications. Cellular and molecular events responsible for the switch from physiologic to pathologic aging of human arteries are less known. Epigenetic, genetic, and environmental influences at the onset of early vascular aging (EVA) should specifically influence the process. This paper briefly reviews the controversial data regarding vascular aging with an emphasis on the less known facts about the morphology of EVA.
Frontiers in genetics, 2017
Increased arterial stiffness (AS), intima-media thickness (IMT), and the presence of atherosclerotic plaques (PP) have been considered as important aspects of vascular aging. It is well documented that the cardiovascular system is an important target organ for growth hormone (GH) and insulin-like growth factor (IGF)-1 in humans, and GH /IGF-1 deficiency significantly increases the risk for cardiovascular diseases (CVD). The telomere length of peripheral blood leukocytes (LTL) is a biomarker of cellular senescence and that has been proposed as an independent predictor of (CVD). The aim of this study is to determine the role of GH/IGF-1, LTL and their interaction cardiovascular risk factors (CVRF) in the vascular aging. The study group included 303 ambulatory participants free of known CVD (104 males and 199 females) with a mean age of 51.8 ± 13.3 years. All subjects had one or more CVRF [age, smoking, arterial hypertension, obesity, dyslipidemia, fasting hyperglycemia, insulin resist...

Objectives: To describe the prevalence of healthy vascular aging (HVA), normal vascular aging and early vascular aging (EVA) in a sample of Spanish population without cardiovascular disease. The relationship of vascular aging with lifestyle, cardiovascular risk factors, psychological and inflammatory risk factors is also analyzed. Methods: A total of 501 participants were recruited (49.70% men, aged 55.90 ± 14.24 years) by random sampling. Vascular aging was defined in three steps: Step 1: participants with vascular damage in carotid arteries or peripheral artery disease were classified as EVA. Step 2: with the percentiles of carotid-to-femoral pulse wave velocity (cfPWV) we used three criteria, first, the 10th and 90th cfPWV percentiles of the population studied by age and sex; second, the 10th and 90th percentiles of the European population reference values and third, the 25th and 75th cfPWV percentiles of the population studied by age and sex. Step 3: participants with hypertensi...
