Usually utilization category is mentioned in most of the switch gear, with the above contactor stating to be used under AC1 - resistive load & AC3 for motor usage. In electrical engineering utilization categories are defined by IEC standards [1] and indicate the type of electrical load and duty cycle of the loads to ease selection of contactors ...
[42] [43] Hydralazine and its derivatives are also used in the treatment of severe hypertension, although they should be avoided in emergencies. [43] They are no longer indicated as first-line therapy for high blood pressure due to side effects and safety concerns, but hydralazine remains a drug of choice in gestational hypertension. [42]
Guidelines for treating resistant hypertension have been published in the UK [45] and US. [46] It has been proposed that a proportion of resistant hypertension may be the result of chronic high activity of the autonomic nervous system, known as "neurogenic hypertension". [47] Low adherence to treatment is an important cause of resistant ...
Angiotensin-converting-enzyme inhibitors (ACE inhibitors) are a class of medication used primarily for the treatment of high blood pressure and heart failure. [1] [2] This class of medicine works by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart.
Hypertensive heart disease includes a number of complications of high blood pressure that affect the heart.While there are several definitions of hypertensive heart disease in the medical literature, [1] [2] [3] the term is most widely used in the context of the International Classification of Diseases (ICD) coding categories.
In patients with one functioning kidney, prompt diagnosis and surgical treatment are needed to prevent irreversible kidney damage and restoration of kidney function. Medical treatment involves use of an angiotensin-converting enzyme inhibitor (ACEi) or an angiotensin receptor blocker (ARB) to control the hypertension. [3]
The term apparent refractory hypertension, as opposed to true refractory hypertension is used by investigators to refer to patients with resistant hypertension based on the number of prescribed medications, without accounting for common causes of pseudo-resistance, ie, inaccurate blood pressure measurements, nonadherence, undertreatment, or white-coat effects. [5]
It is used to treat hypertension as monotherapy or in combination with other antihypertensive agents. [7] [39] The key to the discovery of aliskiren was crystallography and molecular modeling techniques. Now, a solution has been found to the problem that impeded the development of the renin inhibitors of the previous generations.
