Benign hypertension or benign essential hypertension are medical terms now considered obsolete, but once used to describe mild to moderate hypertension (high blood pressure). These historical terms are considered misleading, [1] as hypertension is never benign. Coonsequently, the terms have fallen out of use (see history of hypertension).
Another way to think about hypertension is to categorize it as benign hypertension or malignant hypertension. Benign hypertension is any hypertension that is in stage 1 or stage 2, and typically it causes no immediate symptoms. Malignant hypertension is really severe stage 3 hypertension, and is an emergency because it can cause increased ...
Essential hypertension (also called primary hypertension, or idiopathic hypertension) is a form of hypertension without an identifiable physiologic cause. [1] [2] It is the most common type affecting 85% of those with high blood pressure. [3] [4] The remaining 15% is accounted for by various causes of secondary hypertension. [3]
Lesions reflect leakage of plasma components across vascular endothelium and excessive extracellular matrix production by smooth muscle cells, usually secondary to hypertension. [ 11 ] Hyaline arteriolosclerosis is a major morphologic characteristic of benign nephrosclerosis , in which the arteriolar narrowing causes diffuse impairment of renal ...
Prehypertension is often asymptomatic (without symptoms) at the time of diagnosis. Only extremely elevated blood pressure (malignant hypertension) can, in rare cases, cause headaches, visual changes, fatigue, or dizziness, but these are nonspecific symptoms which can occur with many other conditions. Thus, blood pressures above normal can go ...
A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [2] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.
Both of these definitions had collectively been known as malignant hypertension, although this medical term is replaced. [ citation needed ] In the pregnant patient, the definition of hypertensive emergency (likely secondary to pre-eclampsia or eclampsia) is only a blood pressure exceeding 160 mmHg systolic blood pressure or 110 mmHg diastolic ...
