What does it mean to have benign hypertension?

Term “benign hypertension” is usually slight to moderate severity and of long duration; it does not imply etiology, although most often it is considered “essential” hypertension. Benign nephrosclerosis is the term applied to the renal changes seen with long-standing benign hypertension. Usually asymptomatic.

What causes narrowing of the arterioles?

Increased blood pressure initiates vasospasm and an increase in vasomotor tone owing to local autoregulation, leading to elevation in capillary pressure and flow. This is seen as generalized narrowing of the retinal arterioles.

What is the difference between benign hypertension and malignant hypertension?

In malignant hypertension, the vascular damage is acute, and renin release is a very important part of the pressure increase. In benign, essential hypertension, vascular damage is chronic, and its most important pressure-raising influence is sodium retention.

What does mild arteriolar narrowing mean?

Background: Retinal arteriolar narrowing is a marker of chronic microvascular damage from hypertension. We hypothesized that the presence of retinal arteriolar narrowing increases the likelihood of chronic kidney disease (CKD) associated with hypertension.

What causes benign essential hypertension?

Essential hypertension is a type of high blood pressure that has no clearly identifiable cause, but is thought to be linked to genetics, poor diet, lack of exercise and obesity. It is by far the most common form of high blood pressure, affecting the majority of those who experience hypertension.

Is renal artery stenosis painful?

Stenosis of one renal artery is often asymptomatic for a considerable time. Acute complete occlusion of one or both renal arteries causes steady and aching flank pain, abdominal pain, fever, nausea, and vomiting.

What are the 4 different types of hypertension?

Isolated systolic hypertension, malignant hypertension, and resistant hypertension are all recognized hypertension types with specific diagnostic criteria.

• Isolated systolic hypertension.
• Malignant hypertension.
• Resistant hypertension.

What is focal arteriolar narrowing?

Focal arteriolar narrowing is attributed to localized areas of spasm of the arteriolar wall and can be reversible. Persistent focal arteriolar narrowing may be due to edema in the wall of the arteriole or to localized areas of fibrosis.

What is arteriolar attenuation?

Generalized attenuation of the arterioles results from diffuse vasospasm, which occurs when a significant elevation of blood pressure has persisted for an appreciable period. A relationship has been noted between the narrowing of the caliber of the arteriole and the height of the diastolic pressure.

What is the difference between benign and essential hypertension?

A: Non-essential hypertension is an alternative name for secondary hypertension. Essential hypertension is characterized by a lack of clearly attributable causes, whereas secondary hypertension is directly linked to a variety of vascular, endocrine, heart and kidney conditions.

What are the symptoms of hypertensive arteriolar nephrosclerosis?

Hypertensive arteriolar nephrosclerosis is progressive renal impairment caused by chronic, poorly controlled hypertension. Symptoms and signs of chronic kidney disease may develop (eg, anorexia, nausea, vomiting, pruritus, somnolence or confusion), as may signs of end-organ damage secondary to hypertension.

Is there such thing as benign arteriolar nephrosclerosis?

• Hyaline arteriolosclerosis, in which there is homogeneous pink hyaline thickening of the arteriolar walls, is associated with benign nephrosclerosis.

What does hardening of the renal arterioles mean?

hardening of the kidney, usually associated with hypertension and disease of the renal arterioles. It is characterized as benign or malignant depending on the severity and rapidity of the hypertension and arteriolar changes.

What’s the difference between essential and benign hypertension?

Term “benign hypertension” is usually slight to moderate severity and of long duration; it does not imply etiology, although most often it is considered “essential” hypertension. Benign nephrosclerosis is the term applied to the renal changes seen with long-standing benign hypertension.
