Isolated systolic hypertension (ISH) is the most common form of hypertension in older persons and its predictive value for adverse outcome is well known. However, ISH can be frequently found also in young individuals, especially among males, but its prognostic significance in this setting is still controversial. Increased large artery stiffness is the main determinant of ISH in elderly patients whereas the mechanisms that lead to ISH in the young are still debated. According to some authors ISH in youth is a totally benign condition that can be called "spurious hypertension" a phenomenon due to enhanced pulse pressure amplification of the pulse wave from central to peripheral sites...

Arterial stiffness is an independent predictor of morbidity (infarction, fatal stroke) and cardiovascular mortality, especially in elderly, hypertensive patients with pre-terminal renal insufficiency and in coronary disease patients. The gold standard of its measurement is the pulse wave velocity assessment. The important increase in arterial stiffness that occurs during midlife is associated with the occurrence of severe cardiovascular and cerebrovascular events and also cognitive decline. The causal relationship between stiffening of the arterial tree and cognitive disorders has not yet been clearly established, however, many studies show a relationship between higher levels of aortic stiffness and poorer performance on cognitive memory tests...

BACKGROUND: Carotid-femoral pulse-wave velocity (cf-PWV) and brachial-ankle PWV (ba-PWV) are the 2 most frequently applied PWV measurements. However, little is known about the comparison of hypertensive target organ damage (TOD) with cf-PWV and ba-PWV. METHODS AND RESULTS: A total of 1599 community-dwelling elderly subjects (age >65 years) in northern Shanghai were recruited from June 2014 to August 2015. Both cf-PWV and ba-PWV were measured using SphygmoCor and VP1000 systems, respectively...

The aim of this study was to investigate whether arterial stiffness plays a role in retaining normal diastolic function in a middle-aged and elderly Korean population. A total of 267 patients without documented cardiovascular disease, 50 years and older (mean age, 57.3±6.3 years; 69.8% men) were retrospectively analyzed. All patients underwent both transthoracic echocardiography and brachial-ankle pulse wave velocity measurement on the same day. Patients with septal annular peak velocity (e') ≥8 cm/s and left atrial volume index <34 mL/m(2) were considered as having normal diastolic function...

Left ventricular (LV) diastolic dysfunction and subsequent overt heart failure are more prevalent in elderly women. Close interaction between arterial stiffness and LV morphology/function has been reported. The aim of this study was to investigate whether there is an age- and gender-dependent relationship between arterial stiffness and LV diastolic function. A total of 819 subjects (58.6 ± 13.3 years, 50.2% men) without structural heart disease (LV ejection fraction ≥50%) were retrospectively analyzed...

Aging causes progressive changes in the structure and function of the large arteries that adversely impact the heart and vital organs. Vascular aging is a major independent risk factor for the development of cardiovascular diseases and events. Arterial stiffening is the dominant hemodynamic manifestation of vascular aging and a major independent predictor for incident hypertension. Arterial stiffening is therefore responsible for the very high residual lifetime risk for hypertension for middle-aged and elderly individuals...

Generalized transfer functions (GTFs) are available to compute the more relevant central blood pressure (BP) waveform from a more easily measured radial BP waveform. However, GTFs are population averages and therefore may not adapt to variations in pulse pressure (PP) amplification (ratio of radial to central PP). A simple adaptive transfer function (ATF) was developed. First, the transfer function is defined in terms of the wave travel time and reflection coefficient parameters of an arterial model. Then, the parameters are estimated from the radial BP waveform by exploiting the observation that central BP waveforms exhibit exponential diastolic decays...

Background: Aortic stiffness increases with age and increases pulsatile stress in the microcirculation. Abnormalities in kidney microvascular structure and function may contribute to development or progression of chronic kidney disease in older people. Methods: We performed a longitudinal analysis of 629 community-dwelling elderly Icelandic adults from the Age, Gene/Environment Susceptibility-Reykjavik Study with two visits over a mean follow-up of 5.3 years. We evaluated the associations of carotid-femoral pulse wave velocity (CFPWV), carotid pulse pressure (CPP) and augmentation index (AI), with the change in estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR) assessed as annual change and dichotomized as large changes...

Long and short sleep durations were reported as independently associated with hypertension, aortic stiffness, and cardiovascular disease. High-sensitivity C-reactive protein (hs-CRP) was shown to be associated with increased aortic stiffness. Here, we investigated the relationship between self-reported sleep duration and pulse wave velocity (PWV) in the elderly at high risk of cardiovascular disease. We also investigated whether hs-CRP moderates this relationship. Among 4310 patients with ≥1 cardiovascular risks recruited for the Japan Morning Surge-Home Blood Pressure Study, a questionnaire including items on daily sleep duration was completed...

OBJECTIVES: Hypertension is a risk factor for cognitive impairment and dementia. Arterial stiffness could be involved in the mechanisms of vascular cognitive impairment and in Alzheimer's disease. We examined the association between arterial stiffness, assessed by carotid-femoral pulse wave velocity (PWV), and medial temporal lobe (MTL) atrophy, a biomarker of Alzheimer's disease. METHODS: Elderly community-dwelling study participants (n = 149) with memory complaints were diagnosed with Alzheimer's disease (n = 62) or mild cognitive impairment (n = 87) at a memory clinic...

REVIEW
Mieczyslaw Litwin, Janusz Feber, Marcel Ruzicka
Hypertension (HTN) in children is associated with early vascular aging (EVA) and underlying immunologic-metabolic abnormalities and accelerated biological maturation. Morphologic and functional vascular changes underlying EVA and HTN in children resemble those seen in the elderly including but not limited to an increase in intima-media thickness (IMT) and arterial stiffness and endothelial dysfunction. Although progeria syndrome leading to EVA and the development of clinically manifested cardiovascular (CV) disease in the second decade of life is a rare hereditary disorder, primary HTN, which is also associated with EVA, is much more common (reported in up to 10% in adolescents)...
