Insights

Chronic kidney disease (CKD) is linked to more severe coronary artery calcification (CAC) and coronary artery disease (CAD). Managing CKD alongside traditional risk factors is crucial for preventing CAD, especially when using MDCT screening.

Area of Science:

  • Cardiology
  • Nephrology
  • Radiology

Background:

  • Coronary artery calcification (CAC) scoring via MDCT predicts coronary artery disease (CAD).
  • Chronic kidney disease (CKD) is an established CAD risk factor.
  • The relationship between CKD and the severity of coronary artery stenosis or CAC is not well understood.

Purpose of the Study:

  • To investigate the association between chronic kidney disease (CKD) and coronary artery calcification (CAC) severity.
  • To explore the link between CKD and the extent of coronary artery stenosis.

Main Methods:

  • 313 patients underwent MDCT angiography for CAC scoring and stenosis assessment.
  • Clinical and laboratory parameters, including eGFR, were analyzed.
  • CKD was defined as eGFR <60 mL/min/1.73 m(2).

Main Results:

  • Lower eGFR levels were observed in patients with 3-vessel disease (3-VD).
  • A high CAC score was significantly associated with age, number of diseased vessels, hypertension, and CKD.
  • Multivariate analysis confirmed CKD as a significant correlate of high CAC score.

Conclusions:

  • CKD may exacerbate the severity of CAD and the progression of CAC.
  • Therapeutic interventions targeting CKD are recommended for CAD prevention alongside conventional risk factor management.
  • MDCT screening highlights the importance of considering CKD in CAD risk assessment.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

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...

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
