Postural hypotension in adults: fludrocortisone | Key-points-from-the-evidence | Advice | NICE

There is limited evidence from 2 small short-term studies that fludrocortisone improves postural blood pressure and orthostatic symptoms. In another slightly larger study fludrocortisone had no effect on supine blood pressure or wellbeing in a population with chronic fatigue syndrome.

Exercise Physiology Basics

h4. Introduction To maintain a healthy lifestyle, the importance of physical activity can not be underestimated. It is the single most important endeavor that one can participate in to promote health throughout a lifetime. For decades, epidemiological research has accumulated highlighting the health benefits associated with regular physical activity. Furthermore, there is overwhelming research illustrating the morbid and mortal consequences of being sedentary. The benefits of a proper exercise regimen include: * Increase in the efficiency of cardiovascular and respiratory function * Reduction in coronary artery disease risk factors o Reduction in blood pressure o Increase in HDL and decreased triglycerides ...

Orthostatic Hypotension - American Family Physician

Orthostatic hypotension is a physical finding defined by the American Autonomic Society and the American Academy of Neurology as a systolic blood pressure decrease of at least 20 mm Hg or a diastolic blood pressure decrease of at least 10 mm Hg within three minutes of standing. The condition, which may be symptomatic or asymptomatic, is encountered commonly in family medicine. In healthy persons, muscle contraction increases venous return of blood to the heart through one-way valves that prevent blood from pooling in dependent parts of the body. The autonomic nervous system responds to changes in position by constricting veins and arteries and increasing heart rate and cardiac contractility. When these mechanisms are faulty or if the patient is hypovolemic, orthostatic hypotension may occur. In persons with orthostatic hypotension, gravitational opposition to venous return causes a decrease in blood pressure and threatens cerebral ischemia. Several potential causes of orthostatic hypotension include medications; non-neurogenic causes such as impaired venous return, hypovolemia, and cardiac insufficiency; and neurogenic causes such as multisystem atrophy and diabetic neuropathy. Treatment generally is aimed at the underlying cause, and a variety of pharmacologic or nonpharmacologic treatments may relieve symptoms.

The Thirst Axis

ADH (/vasopressin) is synthesised in the hypothalamus. From there it migrates in neurosecretory granules along axonal pathways to the posterior pituitary gland. Secretion of ADH is principally in response to changes in plasma osmolality. It acts on the collecting duct of the kidney to cause water reabsorption via the translocation of aquaporin channels in the CD lumen, and is therefore stimulated when we need to conserve water volume. It is stimulated by large falls in blood pressure or volume. At high concentrations, ADH also causes vasoconstriction.

Pre-eclampsia and Eclampsia

Pre-eclampsia and eclampsia are different stages of the same condition. Pre-eclampsia can result in eclampsia at any time. Eclampsia is immediately life-threatening and often symptomatic.   Pre-eclampsia is a condition characterised by increased blood pressure, proteinuria and often oedema during pregnancy. It is typically asymptomatic, and occurs after 20 weeks, although it rarely presents before 32 weeks – but when it does, it is associated with a worse prognosis.

Is adrenaline safe and effective as a treatment for out of hospital cardiac arrest?

Adrenaline (epinephrine) has been an integral component of advanced resuscitation algorithms since the early 1960s. Initial guidelines for the treatment of cardiac arrest recommended the use of intracardiac adrenaline (0.5 mg) or high dose intravenous adrenaline (10 mg), repeating with larger doses if required.1 The mechanism of action for adrenaline in cardiac arrest is attributed to stimulation of α2 receptors in vascular smooth muscle, causing vasoconstriction. This increases aortic diastolic pressure, which in turn leads to increased coronary perfusion pressures, which improves short term survival. Experimental studies, however, suggest that adrenaline impairs cerebral macrovascular2 and microvascular blood flow,3 4 increases ventricular arrhythmias, and increases myocardial dysfunction after return of spontaneous circulation.5 This creates the paradox of better short term survival but at the potential cost of worse long term outcomes.
