Renal parenchymal involvement in essential hypertension
The Medical Clinics of North America
|September 1, 1987
Summary
Essential hypertension damages kidneys, with high blood pressure often preceding structural changes. Early detection and treatment of hypertension are crucial for preserving kidney function and preventing end-stage renal disease, especially in susceptible populations.
Area of Science:
- Nephrology
- Cardiology
- Hypertension Research
Background:
- The kidney is a primary target organ in essential hypertension.
- The relationship between renal disease and hypertension has been debated since 1836.
- Hypertension can precede observable structural kidney damage, a condition termed nephrosclerosis.
Purpose of the Study:
- To review the kidney's role in essential hypertension.
- To explore the pathogenesis of hypertension-induced renal damage.
- To discuss therapeutic implications for managing hypertensive patients with renal insufficiency.
Main Methods:
- Review of existing literature on the kidney's involvement in essential hypertension.
- Analysis of the relationship between renal function, structure, and hypertension.
- Examination of hemodynamic changes in early and established hypertension.
Main Results:
- Hypertension accelerates renal vascular aging, leading to nephrosclerosis.
- Intraglomerular hypertension may cause further nephron loss as renal function declines.
- Males and Black individuals are more susceptible to hypertension-induced vascular damage.
- Atherosclerosis of renal arteries is an underrecognized cause of renal failure in hypertensive patients.
- Effective treatment of severe and malignant hypertension can stabilize or improve renal function.
Conclusions:
- Essential hypertension is a significant cause of end-stage renal disease, particularly in Black populations.
- Developing sensitive markers for early renal involvement is critical for timely intervention.
- Therapies targeting both systemic and intraglomerular pressure may benefit hypertensive patients with renal insufficiency.

01:18Hypertension and Regulation of Blood Pressure
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
01:20Renal Corpuscle
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...

01:29Hypertension II: Pathophysiology
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
01:30Hypertension III: Clinical Manifestations and Diagnostic Studies
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
01:29Acute Kidney Injury II: Pathophysiology
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
01:28Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
