Insights

Coronary artery calcification (CAC) progression significantly increases the risk of kidney failure with replacement therapy (KFRT) in patients with chronic kidney disease (CKD). Monitoring CAC changes may help predict CKD progression.

Area of Science:

  • Nephrology
  • Cardiology
  • Public Health

Background:

  • High coronary artery calcification (CAC) burden is a known risk factor for cardiovascular and kidney disease.
  • The relationship between the progression of coronary atherosclerosis and kidney disease progression remains unclear.

Purpose of the Study:

  • To evaluate the association between the progression of coronary artery calcification (CAC) and the risk of kidney failure with replacement therapy (KFRT) in patients with chronic kidney disease (CKD).

Main Methods:

  • Analysis of 1173 participants with CKD (G1-G5) from the KoreaN Cohort Study for Outcomes in Patients With Chronic Kidney Disease (KNOW-CKD).
  • Participants were grouped based on CAC score changes over 4 years: non-progressors (≤0 AU), moderate progressors (1-199 AU), and severe progressors (≥200 AU).
  • The primary outcome was the incidence of KFRT, assessed over a median follow-up of 4.2 years.

Main Results:

  • The incidence of KFRT was higher in moderate (54.3 per 1000 person-years) and severe progressors (80.9 per 1000 person-years) compared to non-progressors (37.6 per 1000 person-years).
  • Multivariable analysis showed significantly increased hazard ratios for KFRT in moderate (HR 1.71) and severe progressors (HR 2.55) versus non-progressors.
  • Sensitivity analysis using a 100 AU threshold for CAC progression yielded similar results.

Conclusions:

  • Progression of coronary artery calcification is independently associated with an elevated risk of kidney failure with replacement therapy in CKD patients.
  • Changes in coronary atherosclerosis burden may contribute to the progression of kidney disease.

Nephrons01:10

Nephrons

The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

Factors Affecting Renal Clearance: Renal Impairment01:17

Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Renal Failure: Dose Adjustments01:11

Renal Failure: Dose Adjustments

In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Heart Failure Drugs: Diuretics01:22

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
