Insights

Ischaemic heart disease is linked to lower bone density in the distal radius. This study used high-resolution peripheral quantitative computed tomography (HR-pQCT) to assess bone health in patients with IHD.

Area of Science:

  • Orthopedics
  • Cardiology
  • Radiology

Background:

  • High-resolution peripheral quantitative computed tomography (HR-pQCT) offers detailed bone assessment.
  • Limited data exist on HR-pQCT findings in patients with ischemic heart disease (IHD).

Purpose of the Study:

  • To investigate bone geometry, volumetric bone mineral density (vBMD), and microarchitecture in individuals with IHD.
  • To compare bone parameters at the distal radius and tibia between IHD patients and controls.

Main Methods:

  • Analysis of data from the Hertfordshire Cohort Study.
  • HR-pQCT scans of the distal radius and tibia in 350 participants (aged 71.5-80.5 years).
  • Comparison of bone parameters between 75 participants with IHD and 275 without IHD.

Main Results:

  • Participants with IHD had lower cortical vBMD (Ct.vBMD) and higher cortical porosity (Ct.Po) at the distal radius.
  • No significant differences in trabecular microarchitecture were observed.
  • Findings were primarily driven by men; no significant associations were found at the distal tibia.

Conclusions:

  • IHD is associated with reduced cortical vBMD at the distal radius.
  • HR-pQCT can detect bone changes related to IHD.

Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Compact Bone01:27

Compact Bone

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

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...

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
