Variations in intradialytic blood pressure (BP) are a common and predictable occurrence in ESRD patients. These are caused by a decrease in blood volume provoked by ultrafiltration, lack of normal compensatory responses to fluid removal, underlying cardiac disease, and electrolyte changes that may adversely affect cardiovascular function. Intradialytic hypotension is ...

β-Adrenoceptor blockers (β-blockers) are one of the oldest classes of cardiovascular drugs still in use. Several short- and long-term clinical outcomes studies have demonstrated their effectiveness and safety for the treatment of hypertension, coronary artery disease, myocardial infarction, heart failure and sudden cardiac death. Due to their safety and efficacy, ...

In numerous epidemiologic, clinical, and experimental studies, dietary sodium intake has been linked to blood pressure, and a reduction in dietary salt intake has been documented to lower blood pressure. In young subjects, salt intake has a programming effect in that blood pressure remains elevated even after a high salt ...

Chronic hypertension affects >1 billion people worldwide and >70 million people in the United States. Acute hypertensive episodes (AHE) are defined as severe spikes in blood pressure that may result in end-organ damage. Although AHE may arise independently as de novo events, they are more likely to occur in patients ...

In daily practice, the Valsalva manoeuvre is used to assess pelvic organ prolapse, virtually always without standardisation of pressure. We undertook a study to determine maximum pressures reached and pressures required to obtain 80% of maximal pelvic organ descent, to investigate the need for such standardisation. Clinical data and ultrasound ...

Pressure-induced urticaria is a non-immunoglobulin E-mediated type of urticaria. Some patients only have angioedema, and the term pressure-induced angioedema (PIA) is more appropriate for them. PIA has not previously been reported in association with endotracheal tube. Here we describe two patients who developed PIA after endotracheal intubation. There were no ...

Introduction: Hypertension is associated with left ventricular hypertrophy (LVH), a predictor of cardiovascular mortality in haemodialysis (HD) patients. The National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) blood pressure (BP) targets are pre-HD <140/90 mm Hg, post-HD <130/80 mm Hg. This study aims to assess 3-month mean in-unit BP, ...

Intracranial pressure (ICP) is affected in many neurological conditions. Clinical measurement of pressure on the brain currently requires placing a probe in the cerebrospinal fluid compartment, the brain tissue, or other intracranial space. This invasiveness limits the measurement to critically ill patients. Because ICP is also clinically important in conditions ...

PURPOSE OF REVIEW: To survey the recent medical literature examining studies of the hemodynamic effects of mechanical ventilation. RECENT FINDINGS: Ventilation-induced dynamic changes in arterial pulse pressure and stroke volume variation (PPV and SVV, respectively) identify volume responsiveness. The cause of PPV and SVV are due to intrathoracic pressure-induced variations ...

: In the critically ill, blood pressure measurements mostly rely on automated oscillometric devices pending the intra-arterial catheter insertion or after its removal. If the arms are inaccessible, the cuff is placed at the ankle or the thigh, but this common practice has never been assessed. We evaluated the reliability ...

Haemodialysis patients show sympathetic hyperactivity. Hyperactivation of the sympathetic nervous system aggravates hypertension and it is related to left ventricular hypertrophy, heart failure, arrhythmias and atherogenesis. We report the first use of renal sympathetic nerve ablation for correction of uncontrolled hypertension in an end-stage renal disease patient on maintenance dialysis. ...

Differential assessment of trunk wounds is a critical element of their effective management. In reviewing the pathology and typical presentation for pressure necrosis, IAD, and ITD, four factors provide guidance in differential assessment: location, depth, characteristics, and exposure. Pressure ulcers are full-thickness lesions located over bony prominences or under medical ...

Takayasu arteritis is a large vessel vasculitis among young women that affects the aorta and its branches. Disease-related subclavian or brachial obstructions can lead to hypotensive brachial blood pressure values. By contrast, arterial hypertension is also frequent in this disease, possibly unrecognized in case of solitary brachial blood pressure measurement. ...

Effusive-constrictive pericarditis (ECP) is an increasingly recognized clinical syndrome. It has been best characterized in patients with tamponade who continue to have elevated intracardiac pressure after the removal of pericardial fluid.

In the era of aggressive control of cardiovascular risk factors such as hypertension, the mantra of "lower is better" has taken a strong foothold. Although there is clear epidemiologic evidence that lower blood pressure improves specific organ-related outcomes, this rule does not apply to all patients and definitely not all ...

Chronic kidney disease (CKD) is associated with a high risk of cardiovascular disease. It is the result of the presence of "traditional" and "nontraditional" risk factors. Hypertension occurs in approximately 80-85% of patients with CKD. The etiology of high blood pressure is multifactorial in this population. Sympathetic nervous system activity ...

Critically ill patients often have deranged hemodynamics. Physical examination, central venous pressure, and pulmonary artery occlusion pressure ("wedge") have been shown to be unreliable at assessing volume status, volume responsiveness, and adequacy of cardiac output in critically ill patients. Thus, invasive and noninvasive cardiac output monitoring is a core feature ...

Apical hypertrophic cardiomyopathy (HCM) is a rare variant of HCM in the non-Japanese population (1% to 2%). Diagnostic dilemma occurs when this type of HCM is newly discovered in a patient previously diagnosed with left ventricular hypertrophy (LVH) secondary to hypertension. We describe an atypical presentation of an apical HCM ...

Morning hypertension is an independent risk factor for cardiovascular diseases, particularly stroke. However, the optimal time at which to take antihypertensive medication to treat morning hypertension remains unclear. We prospectively enrolled elderly patients (over 65 years old) with morning hypertension who had suffered an ischemic stroke (or strokes). Additional treatments ...

This article counters arguments made by Bartels and Otlowski in 2010 regarding euthanasia. It suggests that the authors over-emphasised the importance of individual autonomy in its bearing on the euthanasia debate.

Background/Aim: Oxidative stress (OS) is involved in left ventricular hypertrophy (LVH). Short-term treatment with erythropoietin (EPO) in chronic kidney disease (CKD) complicated by anemia and LVH is associated with a reduction in left ventricular mass (LVM). We proposed to assess whether the pro-oxidant status of CKD influences these outcomes. Methods: ...

The accurate measurement, prediction and treatment of high blood pressure (BP) are essential issues in the management of hypertension. Ambulatory blood pressure monitoring (ABPM) has been shown to be superior to clinic BP measurements as ABPM can provide the following important information: (i) the mean BP levels, (ii) the diurnal ...

The term "prehypertension" defined as systolic blood pressure between 120 and 139 mmHg and/or diastolic pressures between 80 and 89 mmHg has now gained general acceptance. Prehypertension is associated with ~3-fold greater likelihood of developing hypertension, and roughly twice the number of cardiovascular events, than BP < 120/80 mmHg. When ...
