Acute haemodynamic instability is a natural consequence of disordered cardiovascular physiology during haemodialysis (HD). Prevalence of intradialytic hypotension (IDH) can be as high as 20-30%, contributing to subclinical, transient myocardial ischemia. In the long term, this results in progressive, maladaptive cardiac remodeling and impairment of left ventricular function. This is thought to be a major contributor to increased cardiovascular mortality in end stage renal disease (ESRD). Medical strategies to acutely attenuate haemodynamic instability during HD are suboptimal...

Fetal to neonatal transition is characterised by major pulmonary and haemodynamic changes occurring in a short period of time. In the international neonatal resuscitation guidelines, comprehensive recommendations are available on supporting pulmonary transition and delaying clamping of the cord in preterm infants. Recent experimental studies demonstrated that the pulmonary and haemodynamic transition are intimately linked, could influence each other and that the timing of umbilical cord clamping should be incorporated into the respiratory stabilisation...

OBJECTIVE: To compare cardiac index (CI) between Proaqt/PulsioFlex® and esophageal Doppler (OD) and the ability of the PulsioFlex® to track CI changes induced by fluid challenge and secondly to assess the impact of the time interval between two auto-calibrations of PulsioFlex® on the accuracy of the measured CI. METHODS: In a single hospital, 49 intermediate-risk oncologic abdominal surgery patients were included in an observational study. We measured the cardiac Index (CI) provided by OD and by the Proaqt/PulsioFlex® before and after internal calibration, which were performed randomly at specific intervals after the initial one (30, 60, 90 and 120min)...

AIM: Pulmonary thromboendarterectomy (PTE) is a recognized treatment for patients with chronic thromboembolic pulmonary hypertension (CTEPH), with good long-term haemodynamic results. The aim of this study was to test the hypothesis that the dynamics of health-related quality of life (QoL), 1 year after PTE, depends both on the clinical determinants associated with the underlying disease and the adverse events occurring in the early postoperative period. METHODS: This prospective cohort study included 136 patients with CTEPH...

Secondary mitral regurgitation (MR) results from left ventricular dilatation and dysfunction. Quantification of secondary MR is challenging because of the underlying myocardial disease. Clinical and echocardiographic evaluation requires a multi-parametric approach. Severe secondary MR occurs in up to one-fourth of patients with heart failure with reduced ejection fraction, which is associated with a mortality rate of 40% to 50% in 3 years. Percutaneous edge-to-edge mitral valve repair (MitraClip) has emerged as an alternative to surgical valve repair to improve symptoms, functional capacity, heart failure hospitalizations, and cardiac haemodynamics...

Endoscopic retrograde cholangiopancreatography (ERCP) is a commonly used diagnostic and therapeutic technique but it is not free of complications. Subcapsular hepatic haematoma is a rare but potentially fatal complication. A 71-years-old male patient resorted to the emergency department 36 hours after an uneventful ERCP presenting with severe abdominal pain and haemoglobin drop. Abdominal ultrasound and CT scan diagnosed a subcapsular hepatic haematoma. The patient was haemodynamically normal and was successfully treated with a conservative management...

Blood pressure regulation is widely recognised as being integral to the control of end-organ perfusion but it remains unclear whether end-organ perfusion also plays a role in driving changes in blood pressure (BP). A randomized and placebo controlled study design was followed to examine the feedback relationships between very-low-frequency fluctuations in BP and cerebral blood flow (CBF) in humans under placebo treatment and α1-adrenergic blockade. To determine the causal relations among haemodynamic variables, BP, middle cerebral artery blood velocity (MCAv), and end-tidal CO2 time-series were decimated, low-pass filtered (<0...

AIMS: Ischaemic cardiomyopathy (ICM) leads to impaired contraction and ventricular dysfunction, causing high rates of morbidity and mortality. Epigenomics allows the identification of epigenetic signatures in human diseases. We analyse the differential epigenetic patterns of the ASB gene family in ICM patients and relate these alterations to their haemodynamic and functional status. METHODS AND RESULTS: Epigenomic analysis was carried out using 16 left ventricular (LV) tissue samples, eight from ICM patients undergoing heart transplantation and eight from control (CNT) subjects without cardiac disease...

Introduction: It is estimated that the diagnosis of pulmonary embolism (PE) is missed in as many as 84% of all cases of PE. Cardiac arrest following PE is generally associated with poor outcomes. Case Report: A 43-year-old man presented to the Emergency Department (ED) in cardiac arrest. Swelling of his right lower limb was noted on arrival. Point of care ultrasound was performed during ongoing cardiopulmonary resuscitation (CPR) and showed a thrombus in the right iliofemoral vein as well as dilatation of the right ventricle...

BACKGROUND: Atomised intranasal dexmedetomidine administration is an attractive option when sedation is required for paediatric diagnostic procedures, as vascular access is not required. The risk of haemodynamic instability caused by dexmedetomidine necessitates better understanding of its pharmacokinetics in young children. To date, intranasal dexmedetomidine pharmacokinetics has only been studied in adults. METHODS: Eighteen paediatric patients received dexmedetomidine 1 or 2 μg kg-1 intranasally or 1 μg kg-1 i...

OBJECTIVES: The type of conduit used for right ventricular outflow tract (RVOT) reconstruction during the Ross procedure remains problematic because of the limited availability of pulmonary allografts and the unsatisfactory long-term results associated with the use of xenografts. Polytetrafluoroethylene (PTFE) conduits have been proposed as an alternative. This study evaluated the results of RVOT reconstruction using a PTFE conduit during the Ross procedure. METHODS: Between 2007 and 2015, 28 patients underwent RVOT reconstruction using PTFE conduits...

BACKGROUND: In the PATHWAY-2 study of resistant hypertension, spironolactone reduced blood pressure substantially more than conventional antihypertensive drugs. We did three substudies to assess the mechanisms underlying this superiority and the pathogenesis of resistant hypertension. METHODS: PATHWAY-2 was a randomised, double-blind crossover trial done at 14 UK primary and secondary care sites in 314 patients with resistant hypertension. Patients were given 12 weeks of once daily treatment with each of placebo, spironolactone 25-50 mg, bisoprolol 5-10 mg, and doxazosin 4-8 mg and the change in home systolic blood pressure was assessed as the primary outcome...
