Avishay Elis, Amit Akirov
AIMS: To determine the rate of hypertensive patients hospitalized at the department of medicine who are treated or are candidates for fixed dose drug combinations. BACKGROUND: Despite the high prevalence of hypertension and rates of awareness, The number of patients treated and well controlled are low. The main reasons for not achieving blood pressure target levels are compliance and persistence with drug therapy. METHODS: A multicenter, retrospective records review was conducted of hypertensive patients hospitalized at departments of medicine during 2014...

PURPOSE: To investigate the prevalence of visual field defects in glaucomatous eyes, glaucoma suspects, and ocular hypertensives with 24-2 and 10-2 visual fields. DESIGN: Prospective, cross-sectional study. PARTICIPANTS: Patients with or suspected glaucoma tested with 24-2 and 10-2. Patients were classified into 3 groups on the basis of the presence of glaucomatous optic neuropathy (GON) and 24-2 visual field abnormalities: early glaucoma (GON and abnormal visual field, mean deviation >-6 decibels [dB]), glaucoma suspects (GON and normal visual field), and ocular hypertensives (normal disc, normal visual field, and intraocular pressure >22 mmHg)...

BACKGROUND: Torso hemorrhage constitutes a leading cause of battlefield mortality. The Abdominal Aortic and Junctional Tourniquet (AAJT) uses a pneumatic bladder to compress the aorta reducing pelvic and lower extremity perfusion; however, concern exists over the risk of caval compression exacerbating hypotension after application. METHODS: Male swine (70-90 kg) were randomized into four groups of 10: presence or absence of hemorrhage and AAJT placement. After a 40% hemorrhage, a 15-min period of hypovolemia was observed before the AAJT application...

To assess the value of computed tomography (CT) for non-invasive detection of pulmonary hypertension (PH) in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) and to correlate CT measurements and signs with mortality after TAVI. 257 TAVI patients (median 84 years; 134 females) with both right heart catheterisation (RHC) and CT within 3 days were retrospectively analyzed. According to guidelines PH was defined as mean pulmonary artery pressure ≥25 mmHg in RHC. CT-signs for PH assessment were evaluated...

Obstructive sleep apnea (OSA) is a known-risk factor for cardiovascular diseases. There are indications that treatment with continuous positive airway pressure (CPAP) reduces the risk of new cardiovascular events. In this study, we analyzed the incidence of cardiovascular events in patients with OSA and compared for the impact of CPAP therapy. All polysomnographies performed in 2009 and 2010 were selected with an AHI ≥5 and patients older than 18 years. These 1110 patients were approached with a questionnaire about cardiovascular events and CPAP treatment...

PURPOSE: To investigate the impact of surgical or medical reduction of intraocular pressure (IOP) on progressive normal-tension glaucoma followed up over 15 years. METHODS: Sixty eyes of 60 patients were divided into 3 intervention groups: group 1 (trabeculectomy, n = 17); group 2 (IOP reduction rate ≥15% with prostaglandin analogs, n = 24); and group 3 (IOP reduction rate <15% with prostaglandin analogs, n = 19). The preintervention and postintervention mean deviation (MD) slopes and IOP were compared...

The relevance of right atrial pressure (RAP) as the back-pressure for venous return (QVR) and mean systemic filling pressure (MSFP) as up-stream pressure is controversial during dynamic changes of circulation. To examine the immediate response of QVR (sum of caval vein flows) to changes in RAP and pump function we used a closed chest, central cannulation, heart bypass porcine preparation (n=10) with veno-arterial extracorporeal membrane oxygenation (ECMO). MSFP was determined by clamping ECMO tubing with open or closed arterio-venous shunt at Euvolemia, Volume Expansion (9...

BACKGROUND: The Melody(®) pulmonary valve has received approval for the treatment of dysfunctional right ventricular (RV) outflow tract conduits ≥16mm. AIMS: To investigate technical and clinical outcomes in patients who underwent percutaneous pulmonary valve implantation (PPVI) in conduits ≤16mm. METHODS: Eleven patients were enrolled retrospectively between 2000 and 2015 in a cardiac referral centre. RESULTS: The PPVI indications were obstruction (n=5); regurgitation (n=1); and mixed lesions (n=5)...

Increased sympathetic nerve activity and the activation of the central renin-angiotensin system are commonly associated with cardiovascular disease states such as hypertension and heart failure, yet the precise mechanisms contributing to the long-term maintenance of this sympatho-excitation are incompletely understood. Due to the established physiological role of neurotrophins contributing toward neuroplasticity and neuronal excitability along with recent evidence linking the renin-angiotensin system and brain-derived neurotrophic factor (BDNF) along with its receptor (TrkB), it is likely the two systems interact to promote sympatho-excitation during cardiovascular disease...

BACKGROUND: The use of hyperosmolar agents such as mannitol or hypertonic saline (HTS) to control high intracranial pressure (ICP) in traumatic brain injury patients has been well studied. However, the role of HTS in the management of aneurysmal subarachnoid hemorrhage (aSAH)-associated raised ICP is still unclear. METHODS: We performed a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The primary outcome of this review is to quantify ICP reduction produced by HTS and its effect on clinical outcomes defined by any standardized functional score...

The added value of incorporating information from repeated measurements of blood pressure and cholesterol for cardiovascular disease (CVD) risk prediction has not been rigorously assessed. We used data from the Emerging Risk Factors Collaboration on 191,445 adults (38 cohorts from across 17 countries with data from 1962-2014) with > 1 million measurements of systolic blood pressure, total cholesterol and high-density lipoprotein cholesterol; over a median 12 years of follow-up, 21,170 CVD events occurred...

Curcumin is the main ingredient of turmeric, a common Indian spice. Curcumin shows a broad spectrum of effects, including anti-Alzheimer's and anti-oxidant properties. An interaction between curcumin and lipid membranes has been speculated as the root-cause, and the molecule is often proposed to `protect' the bilayer. However, the detailed molecular mechanism of this protection is disputed. There is evidence that curcumin either a) lies flat on the bilayer and provides a `carpet' for protection by forming a steric barrier, or b) inserts into the membrane and stiffens tails, thereby protecting against peptide insertion...

The aim of this work was to evaluate the short-term fractal index (α1 ) of heart rate variability (HRV) in chronic renal failure (CRF) patients by identifying the effects of orthostatism and hemodialysis (HD), and by evaluating the correlation between α1 and the mean RR interval from sinus beats (meanNN). HRV time series were derived from ECG data of 19 CRF patients and 20 age-matched healthy subjects obtained at supine and orthostatic positions (lasting 5 min each). Data from CRF patients were collected before and after HD...

BACKGROUND AND PURPOSE: Phosphodiesterase enzymes (PDE1-11) break down cyclic nucleotides and are important in the regulation of the cardiovascular system. The purpose of the present study was to investigate the effect on the cardiovascular system of two novel selective PDE1 inhibitors, Lu AF41228 and Lu AF58027. EXPERIMENTAL APPROACH: We used rat mesenteric small arteries (internal diameters of 200-300 µm), RT-PCR and measurement of isometric wall tension. The effect of Lu AF41228 and Lu AF58027 on heart rate and blood pressure was assessed in both anesthetized and conscious male rats...
