BACKGROUND: Central systolic and pulse pressures are markers of risk for small vessel disease in the brain and kidneys. The extent to which these markers are reproducible in the setting of population studies is less well established. We estimated short-term repeatability of central systolic and pulse pressures, and those of their peripheral measures for comparison. METHODS: Participants aged 65 years and over (n = 79, 56% women) were drawn from the 2011-2013 examination of the ARIC cohort...

The aim of the study was to investigate the association of left ventricular diastolic dysfunction (LVDD) with central and peripheral hemodynamics. A total of 1599 community-based senior residents (aged ≥ 65 years) in northern Shanghai, China, were recruited as of August 2015. Echocardiography was performed for each participant using the MyLab30 Gold CV system. According to the recommendations from the American Society of Echocardiography, the ratio of E (peak early diastolic transmitral flow velocity) to E' (early diastolic lateral mitral annulus velocity) was assessed for the evaluation of LVDD...

BACKGROUND: Increased carotid-femoral pulse wave velocity (PWV) has been associated with incident cardiovascular disease, independently of traditional risk factors. Cardiac autonomic dysfunction is a common complication of diabetes and has been associated with reduced aortic distensibility. However, the association of cardiac autonomic dysfunction with PWV is not known. In this study we examined the association between cardiac autonomic function and PWV in subjects with type 2 diabetes mellitus...

BACKGROUND: Renal sympathetic denervation seems to be less effective as a treatment for hypertension in patients with isolated systolic hypertension, a condition associated with elevated central arterial stiffness. Because isolated systolic hypertension can also be caused by wave reflection or increased cardiac output, a more differentiated approach might improve patient preselection for renal sympathetic denervation. We sought to evaluate the additional predictive value of invasive pulse wave velocity for response to renal sympathetic denervation in patients with combined versus isolated systolic hypertension...

INTRODUCTION: Arterial blood sampling, used to assess patients in acute conditions, may result in complications such as thrombosis and embolism. However, it can be replaced by venous blood sampling, but there is a dearth of information on this. AIM: To assess the correlation and agreement between the arterial and central venous blood gases analyses in patients undergoing elective Coronary Artery Bypass Graft (CABG) surgery. MATERIALS AND METHODS: In this cross-sectional study, 100 ICU patients undergoing elective CABG surgery were recruited...

OBJECTIVES: In the context of screening for diabetes, we examined levels of central haemodynamics among individuals with different levels of diabetes risk and analysed the impact of glycated haemoglobin A (HbA1c) and HbA1c changes on central haemodynamics. METHODS: A Danish population-based stepwise screening programme for diabetes including a diabetes risk score (DRS) questionnaire and glucose measurements identified seven groups of individuals at increasing levels of diabetes risk...

Management with intravenous fluids can improve cardiac output in some surgical patients. Management with static preload indicators, such as central venous pressure and pulmonary artery occlusion pressure, has not demonstrated a suitable relationship with changes in the cardiac output induced by intravenous fluid therapy. Dynamic indicators, such as the variability of arterial pulse pressure or stroke volume variation, have demonstrated a suitable relationship. Since improvement in cardiac output does not guarantee an adequate perfusion pressure, in patients with hypotension, it is also necessary to know whether arterial pressure will also increase with intravenous fluid therapy...

BACKGROUND: Arterial reservoir characteristics are related to blood pressure (BP) and independently predict cardiovascular events. It is unknown if arterial reservoir characteristics are modified from the central-to-peripheral large arteries and whether there is a contributory role to BP amplification. The aim of this study was to assess central-to-peripheral changes in arterial reservoir characteristics and determine associations with BP. METHODS: Reservoir pressure (RP) and excess pressure (XSP) were derived from intra-arterial BP waveforms among 51 participants (aged 63 ± 13 years, 63% men) undergoing clinically indicated cardiac angiography...

This study aimed to investigate whether sedentary time (Sed) and physical activity (PA) are associated with arterial stiffness in individuals with and without metabolic syndrome (MetS). This cross-sectional study comprised 197 individuals (47±13 years; 58% female) from a primary health care centre. Arterial stiffness was assessed using carotid-femoral pulse wave velocity (cfPWV). Metabolic syndrome was determined as clustering of at least 3 out of 5 risk factors (central obesity, hypertension, impaired glucose, triglycerides and high-density lipoprotein cholesterol)...

PURPOSE: To compare the effect of 2 different methods of transepithelial corneal collagen cross-linking (CXL) on corneal histology and hysteresis. METHODS: The right eyes of New Zealand white rabbits (n = 50) were treated using one of the 2 transepithelial CXL methods. The eyes were then divided into 2 groups: group 1, transepithelial CXL using continuous ultraviolet A (UVA); group 2, accelerated transepithelial CXL using pulsed UVA. RESULTS: Both groups showed a postoperative increase in central corneal thickness...

Arterial stiffness and augmentation of aortic blood pressure (BP) measured in office are known cardiovascular risk factors in hemodialysis patients. This study examines the prognostic significance of ambulatory brachial BP, central BP, pulse wave velocity (PWV), and heart rate-adjusted augmentation index [AIx(75)] in this population. A total of 170 hemodialysis patients underwent 48-hour ambulatory monitoring with Mobil-O-Graph-NG during a standard interdialytic interval and followed-up for 28.1±11.2 months...

This study was conducted to clarify the clinical significance of the RRI in Fontan pathophysiology. METHODS: We measured the RRI in 280 consecutive Fontan patients and 36 healthy controls. RESULTS: The patients exhibited a higher RRI than the controls (0.71±0...

Objective: To observe the changes of arm equilibrium pressure (P(arm)) in different occlusion time, the reference range of P(arm) in hemodynamic stable patients, and to explore the relationship between P(arm) and systemic hemodynamic parameters. Methods: Mechanically ventilated postoperative abdominal surgery patients who admitted to ICU with stable hemodynamic status were enrolled. After hemodynamic data were recorded, arm stop-flow maneuvers were performed to measure P(arm). At 10, 20, 30, 40, 50, 60 seconds after occlusion, arterial pressure were measured twice within 5 minutes and recorded as the average value...

We investigated age-related change in the contribution of stroke volume (SV) to central PP (cPP). Eighty seven adult subjects who were free of vasoactive agents were included. Subjects were divided into three age groups: young (20-39 years, n = 26), middle (40-49 years, n = 29), and old (≥50 years, n = 32). SV was calculated by Doppler echocardiography. Hemodynamic indices were measured using a brachial cuff-based oscillometric method. The brachial and cPP showed a small decline from the young group to the middle group and a greater rise after 50 years old...

Nesfatin/nucleobindin-2 (nesf/NUCB2), a precursor of the anorexigenic protein nesfatin-1, is selectively expressed in the hypothalamic nuclei, which are central to the regulation of the autonomic nervous system. The present study sought to investigate the involvement of nesf/NUCB2 in the regulation of blood pressure and ingestive behavior, by using nesf/NUCB2-transgenic (Tg) mice. Blood pressure and heart rates were measured under conscious and unconscious conditions. Twenty-four-hour water intake and urine volume of male nesf/NUCB2-Tg mice and their littermates in metabolic cages were measured...
