Beat-to-beat variability of aortic pulse wave velocity: implications for aortic stiffness measurements.

Objectives: Aortic pulse wave velocity (aPWV) predicts cardiovascular risk. Being the reference method for aortic stiffness evaluation, invasive aPWV is also recommended for validation of noninvasive devices. Because of intrinsic haemodynamic variability and processing issues, aPWV shows beat-to-beat variability.

Renal Denervation in End-Stage Renal Disease: Current Evidence and Perspectives.

In patients with end-stage renal disease (ESRD) undergoing haemodialysis, hypertension is of common detection and frequently inadequately controlled. Multiple pathophysiological mechanisms are involved in the development and progression of the ESRD-related high blood pressure state, which has been implicated in the increased cardiovascular risk reported in this hypertensive clinical phenotype. Renal sympathetic efferent and afferent nerves play a relevant role in the development and progression of elevated blood pressure values in patients with ESRD, often leading to resistant hypertension.

Telemedicine and Digital Medicine in the Clinical Management of Hypertension and Hypertension-Related Cardiovascular Diseases: A Position Paper of the Italian Society of Arterial Hypertension (SIIA).

High blood pressure is the leading cause of death and disability globally and an important treatable risk factor for cardiovascular, cerebrovascular and chronic kidney diseases. Digital technology, including mobile health solutions and digital therapy, is expanding rapidly in clinical medicine and has the potential to improve the quality of care and effectiveness of drug treatment by making medical interventions timely, tailored to hypertensive patients' needs and by improving treatment adherence. Thus, the systematic application of digital technologies could support diagnosis and awareness of hypertension and its complications, ultimately leading to improved BP control at the population level.

Exercise Intensity and Activity Energy Expenditure of Professional Golf Players in Official Competitive Setting.

Background: Research regarding the physical needs of professional golf players is lacking. With advances in wearable technology, it has become easier to analyze physiological responses such as heart rate (HR) to determine activity energy expenditure (AEE). The purpose of the study was to evaluate exercise intensity (EI) and AEE during 4 consecutive tournament's golf rounds using a popular wrist-based HR monitoring.

Comparison Between Invasive and Noninvasive Methods to Estimate Subendocardial Oxygen Supply and Demand Imbalance.

Background Estimation of the balance between subendocardial oxygen supply and demand could be a useful parameter to assess the risk of myocardial ischemia. Evaluation of the subendocardial viability ratio (SEVR, also known as Buckberg index) by invasive recording of left ventricular and aortic pressure curves represents a valid method to estimate the degree of myocardial perfusion relative to left ventricular workload. However, routine clinical use of this parameter requires its noninvasive estimation and the demonstration of its reliability.

Sheath Size Up and Down With Single Proglide - A Technique for Achieving Hemostasis With Use of Large Size Delivery System During Endovascular Graft Placement.

Background: A total percutaneous approach for management of aortic pathologies with endovascular grafts requires the use of large size delivery-systems. The diameter of these delivery systems usually exceeds the recommended sizes for most of the currently available percutaneous closure devices. A safe, effective and simple vascular access site closure device is desirable for success for percutaneous procedures for aortic pathologies.

Heart rate variability, postural sway and electrodermal activity in competitive golf putting.

Background: Stressful conditions during competitive golf putting may result in impaired performance, producing physiological changes. Nevertheless, simultaneous measurements of postural sway (PS), heart rate variability (HRV) and electrodermal activity (EDA) during a competitive golf putting have not yet been examined. This study aims at describing if changes in PS, HRV and EDA during golf putting, might affect the golfer's performance.

European Society of Hypertension position paper on renal denervation 2021.

This ESH Position Paper 2021 with updated proposed recommendations was deemed necessary after the publication of a set of new pivotal sham-controlled randomized clinical trials (RCTs), which provided important information about the efficacy and safety of endovascular device-based renal denervation (RDN) for hypertension treatment. RDN is effective in reducing or interrupting the sympathetic signals to the kidneys and decreasing whole body sympathetic activity. Five independent, fully completed, sham-controlled RCTs provide conclusive evidence that RDN lowers ambulatory and office blood pressure (BP) to a significantly greater extent than sham treatment.

Closure of an unusual morphology patent ductus arteriosus with a covered stent in a dog.

Patent ductus arteriosus (PDA) with unusual morphology was diagnosed in a 3-year-old German shepherd presented for exercise intolerance. Two interventional PDA closure procedures with various Amplatzer devices and one surgical ligation were attempted to close the PDA. However, PDA closure failed with both methods due to the unusual morphology and the severe enlarged ductus ampulla.

Ambulatory blood pressure monitoring by a novel cuffless device: a pilot study.

Purpose: Cuffless blood pressure (CL-BP) measurements are believed to be a potentially alternative to cuff-occlusion-based (C-BP) measurement. A new cuffless device was developed for ambulatory BP monitoring. We assessed the accuracy of a new CL-BP device compared to a standard oscillatory C-BP device over the 24 h.

Hypertension in aortic stenosis: a focused review and recommendations for clinical practice.

: In patients with aortic stenosis, the presence of hypertension negatively affects the hemodynamic severity of the stenosis, and worsens adverse left ventricular remodeling. It accelerates the progression of the stenosis and is associated with worse prognosis. Proper management of hypertension is thus crucial but there are concerns about the safety and efficacy of antihypertensive medications as well as uncertainty about optimal blood pressure (BP) targets and their impact on left ventricular mass regression and survival benefits.

Renal denervation in patients with end-stage renal disease and resistant hypertension on long-term haemodialysis.

Introduction: Recent randomized controlled trials have confirmed the ability of renal denervation to lower blood pressure (BP) in patients, resistant to the BP-lowering effect of multiple antihypertensive drug administration. Evidence is limited, however, in patients with end-stage renal disease (ESRD) and haemodialysis, a condition in which a persistent BP elevation, despite administration of many antihypertensive drugs, is common. Aim of the present study was to test the BP-lowering efficacy of renal denervation in patients with resistant hypertension and ESRD on haemodialysis.

Noninvasive Estimation of Aortic Stiffness Through Different Approaches.

Aortic pulse wave velocity is a worldwide accepted index to evaluate aortic stiffness and can be assessed noninvasively by several methods. This study sought to determine if commonly used noninvasive devices can all accurately estimate aortic pulse wave velocity. Pulse wave velocity was estimated in 102 patients (aged 65±13 years) undergoing diagnostic coronary angiography with 7 noninvasive devices and compared with invasive aortic pulse wave velocity.

A new Percutaneous technique for effective vascular Access Site closure in patients undergoing Transfemoral aortic valve implantation and thoraco-abdominal aortic aneurysm rEpair: the PASTE study.

Aims: The success of transfemoral transcatheter aortic valve implantation (TAVI) and thoraco-abdominal aneurysm repair (TAAR) depends on haemostatic control of the access site, which is usually obtained with suture-based closure devices (Prostar or two ProGlide). A single ProGlide/Glubran technique, involving a suture placement on the vessel wall followed by tissue glue injection around the vessel wall, has not been previously investigated in this clinical setting. Our aim was to study the feasibility and safety of a single ProGlide/Glubran technique for vascular access-site closure after transfemoral TAVI and TAAR.

Short-Term Repeatability of Noninvasive Aortic Pulse Wave Velocity Assessment: Comparison Between Methods and Devices.

Background: Aortic pulse wave velocity (PWV) is an indirect index of arterial stiffness and an independent cardiovascular risk factor. Consistency of PWV assessment over time is thus an essential feature for its clinical application. However, studies providing a comparative estimate of the reproducibility of PWV across different noninvasive devices are lacking, especially in the elderly and in individuals at high cardiovascular risk.

Occlusive Shrinkage of Ovation Endograft Presenting as Acute Lower Limb Ischemia: Effective Endovascular Management.

The aim of this report is to describe the imaging and successful treatment of an acute shrinkage of the Ovation Abdominal Stent Graft System. The Ovation Prime system utilizes a polymer-filled sealing ring that is cast at the margin of the aneurysm; however, the residual endograft inner volume after ring filling may reduce volume and graft flow. Nevertheless, there are no reports about severe complications using the Ovation Prime system.

Asymmetric and Symmetric Dimethylarginine and Sympathetic Nerve Traffic after Renal Denervation in Patients with Resistant Hypertension.

Background And Objectives: The plasma concentration of the endogenous inhibitor of nitric oxide synthase asymmetric dimethylarginine (ADMA) associates with sympathetic activity in patients with CKD, but the driver of this association is unknown.

Design, Setting, Participants, & Measurements: In this longitudinal study (follow-up: 2 weeks-6 months), repeated measurements over time of muscle sympathetic nerve activity corrected (MSNAC), plasma levels of ADMA and symmetric dimethylarginine (SDMA), and BP and heart rate were performed in 14 patients with drug-resistant hypertension who underwent bilateral renal denervation (enrolled in 2013 and followed-up until February 2014). Stability of ADMA, SDMA, BP, and MSNAC over time (6 months) was assessed in two historical control groups of patients maintained on stable antihypertensive treatment.

Automated carbon dioxide digital angiography for lower-limb arterial disease evaluation: safety assessment and comparison with standard iodinated contrast media angiography.

Introduction: Carbon dioxide (CO2) has been validated as a contrast agent in a large series of studies. A particular advantages of CO2 over iodinated contrast medium (ICM) is the absence of nephrotoxicity and allergic reactions. One of the limitations of CO2 angiography is the difficulty of CO2 manual injection due to its compressibility.
