Implications of pulse wave velocity and central pulse pressure in heart failure with reduced ejection fraction.

Background: Carotid-femoral pulse wave velocity (cfPWV) and central pulse pressure (PP) are recognised as significant indicators of vascular health and predictors of cardiovascular outcomes. In this study, associations between central hemodynamics and left ventricular (LV) echocardiographic parameters were investigated in subjects with heart failure with reduced ejection fraction (HFrEF), comparing the results to healthy individuals.

Methods And Results: This cross-sectional prospective controlled study included 50 subjects with HFrEF [mean LV ejection fraction (EF) 26 ± 6.

Lifeday coverage of oral anticoagulants and one-year relative survival in patients with atrial fibrillation: a population-based study in Estonia.

Background: Routine oral anticoagulation (OAC) is recommended for almost all high-risk patients with atrial fibrillation, yet registries show that OACs are still underused. Our aim was to study the lifeday coverage (LDC) of OAC prescriptions and its relationship with one-year mortality rates of AF patients aged ≥ 65 in Estonia for the years 2019 and 2020.

Methods: Medical data for AF patients aged ≥ 65 years from 2018 and alive as of 01.

Markers of Inflammation, Oxidative Stress, and Fibrosis in Patients with Atrial Fibrillation.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice. The pathogenesis of AF is linked to inflammatory reaction and oxidative stress, which leads to fibrosis of the atria and progression of the disease. The purpose of this study was to define the role of several biomarkers of inflammation, fibrosis, and oxidative stress (OxS).

The authors included 76 patients with paroxysmal/persistent AF.

Atenolol's Inferior Ability to Reduce Central vs Peripheral Blood Pressure Can Be Explained by the Combination of Its Heart Rate-Dependent and Heart Rate-Independent Effects.

Objective: Whether the inferior ability of atenolol to reduce central (aortic) compared to peripheral (brachial) blood pressure (BP) is related to its heart rate (HR)-dependent or -independent effects, or their combination, remains unclear. To provide further mechanistic insight into this topic, we studied the acute effects of atenolol versus nebivolol and ivabradine on systolic blood pressure amplification (SBPA; peripheral systolic BP minus central systolic BP) in a model of sick sinus syndrome patients with a permanent dual-chamber cardiac pacemaker in a nonrandomized single-blind single-group clinical trial.

Methods: We determined hemodynamic indices noninvasively (Sphygmocor XCEL) before and at least 3 h after administration of oral atenolol 50 or 100 mg, nebivolol 5 mg, or ivabradine 5 or 7.

Jürgenson, J, Serg, M, Kampus, P, Kals, J, Zagura, M, Viru, M, Zilmer, K, Zilmer, M, Eha, J, and Unt, E. Oxidative stress parameters and its associations with arterial stiffness in competitive powerlifting athletes after 12-week supervised strength training. J Strength Cond Res 33(7): 1816-1822, 2019-Available studies have not revealed a clear understanding of the impact of intensive strength training on arterial stiffness and oxidative stress (OxS) parameters, which may have a significant impact on further cardiovascular health of an athlete.

Heart rate reduction decreases central blood pressure in sick sinus syndrome patients with a permanent cardiac pacemaker.

Increased resting heart rate (HR) contributes to higher cardiovascular mortality and morbidity in the healthy as well as in people with cardiovascular diseases, possibly due to elevated blood pressure (BP) among other mechanisms. Data on the relationship between HR and central (aortic) BP remains controversial, however, and concerning β-blockers, it has been proposed that pharmacological HR lowering is associated with augmentation of central BP. We aimed to study the role of pharmacologically unaffected HR on central BP indices in sick sinus syndrome patients with a permanent cardiac pacemaker in the HR range from 40 to 90 bpm.

Metabolomic signature of arterial stiffness in male patients with peripheral arterial disease.

Arterial stiffness is an independent determinant of cardiovascular risk and a marker of subclinical organ damage. Metabolomics may facilitate identification of novel low-molecular cardiovascular risk factors. The aim of the present study was to compare metabolic signatures and functional-biochemical characteristics of patients with peripheral arterial disease (PAD) and clinically healthy subjects.

Angiotensin II receptor blocker telmisartan attenuates aortic stiffening and remodelling in STZ-diabetic rats.

Background: Prevention or attenuation of diabetic vascular complications includes anti-hypertensive treatment with renin-angiotensin system inhibitors on account of their protective effects beyond blood pressure reduction. The present study aimed to investigate the effects of telmisartan, an angiotensin II type 1 receptor blocker (ARB), on blood pressure, aortic stiffening, and aortic remodelling in experimental type 1 diabetes in rats.

Methods: Diabetes was induced by streptozotocin (STZ) (65 mg/kg) in male Wistar rats.

Heat acclimation increases arterial elasticity in young men.

The major physiological adaptations that occur during heat acclimation (HA) are well documented. However, no studies have provided compelling evidence about the effect of HA on arterial elastic properties. The aim of this study was to examine the changes in large artery elasticity (LAE) and small artery elasticity (SAE) concomitant with HA and to determine the potential relationships among changes in arterial elasticity, baseline aerobic fitness level, and improvement in endurance capacity (EC).

Vitamin D reduces deposition of advanced glycation end-products in the aortic wall and systemic oxidative stress in diabetic rats.

Aims: Vitamin D may have an important role in reducing the risk of cardiovascular disease. Advanced glycation end-products (AGEs) such as Nε-(carboxymethyl)lysine (CML), have been implicated in diabetic vascular complications via oxidative stress-mediated pathways. We investigated the potential protective effect of vitamin D on CML accumulation in the diabetic aortic wall.

Structural and biochemical characteristics of arterial stiffness in patients with atherosclerosis and in healthy subjects.

Arterial stiffness is an independent predictor of vascular morbidity and mortality in patients with atherosclerosis. Angiographic score (ASc) reflects severity of atherosclerosis in patients with peripheral arterial disease (PAD). Osteopontin (OPN) and oxidized low-density lipoprotein (oxLDL) are involved in the pathogenesis of atherosclerosis.

Nebivolol and metoprolol: long-term effects on inflammation and oxidative stress in essential hypertension.

Arterial hypertension is characterised by increased oxidative stress and inflammation, which are associated with further cardiovascular risk. The aim of our study was to investigate the long-term effects of nebivolol and metoprolol succinate on oxidative stress, and on inflammatory and pro-inflammatory markers in patients with hypertension. Eighty patients with never-treated mild-to-moderate essential hypertension, aged 30-65 years, were randomised to a 5 mg daily dose of nebivolol or a 50-100 mg daily dose of metoprolol succinate.

Effect of vitamin D on aortic remodeling in streptozotocin-induced diabetes.

Background: Diabetes mellitus is associated with micro- and macrovascular complications and increased cardiovascular risk. Elevated levels of serum asymmetric dimethylarginine (ADMA) may be responsible for endothelial dysfunction associated with diabetes-induced vascular impairment. Vitamin D may have potential protective effects against arterial stiffening.

The aim of this study was to investigate the effects of the vasodilating β-blocker nebivolol and the cardioselective β-blocker metoprolol succinate on aortic blood pressure and left ventricular wall thickness. We conducted a randomized, double-blind study on 80 hypertensive patients. The patients received either 5 mg of nebivolol or 50 to 100 mg of metoprolol succinate daily for 1 year.

β2-microglobulin, a novel biomarker of peripheral arterial disease, independently predicts aortic stiffness in these patients.

Arterial stiffness is a prominent feature of vascular ageing and strongly predicts cardiovascular and total mortality. The β2-microglobulin, (β2M) a newly identified biomarker of peripheral arterial disease (PAD), is related to renal insufficiency, inflammatory and neoplastic diseases, but may also play a role in vascular dysfunction. However, the relationship between arterial stiffness and β2M has not been previously studied in patients with atherosclerosis.

Association between asymmetric dimethylarginine and indices of vascular function in patients with essential hypertension.

Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthase and is associated with endothelial dysfunction. The aim of the present study was to investigate the relationship between ADMA, indices of arterial stiffness, endothelial function and carotid artery intima-media thickness (IMT) in hypertension patients. Eighty middle-aged (47 ± 10 years) untreated patients with mild to moderate essential hypertension underwent routine physical examination, pulse wave analysis (PWA), measurement of aortic pulse wave velocity (PWV) and IMT.

Association of osteoprotegerin with aortic stiffness in patients with symptomatic peripheral artery disease and in healthy subjects.

Background: Arterial stiffening is an independent predictor for cardiovascular mortality. Preliminary studies have shown that arterial calcification may have an impact on increased vascular stiffness. However, there are limited data about the role of calcification inhibitor osteoprotegerin (OPG) as an independent predictor for arterial stiffness in patients with peripheral arterial disease (PAD) and in healthy subjects.

Objective: The present study investigated the functional-structural changes of the arteries along with a new biochemical marker of atherosclerosis, plasma myeloperoxidase level, in children with type 1 diabetes (T1DM).

Methods: We studied 30 children with T1DM, aged 4.7-18.

Association between arterial elasticity, C-reactive protein and maximal oxygen consumption in well-trained cadets during three days extreme physical load: a pilot study.

Regular aerobic training has beneficial effects on inflammatory pathways and on arterial elasticity, which are both important cardiovascular risk factors. The aim of the present study was to evaluate the effect of extreme physical load on arterial elasticity and inflammatory markers in well-trained healthy men who participated in a high-ranking combat course. Seven well-trained male cadets were examined during an international military combat course of 3.

Inflammation and oxidative stress are associated differently with endothelial function and arterial stiffness in healthy subjects and in patients with atherosclerosis.

Inflammation and oxidative stress (OxS) play key roles in atherogenesis; however, their causal relationship is not yet completely understood. Much attention has been given to the possibility that inflammation is a primary process of atherosclerosis and that OxS may be a by-product of the inflammatory process. We hypothesized, accordingly, that chronic systemic inflammation affects endothelial vasomotor function in the subclinical condition, whereas oxidative modifications are more involved in the structural stiffening of the arteries in atherosclerosis.
