Insights

Early detection of vascular changes like increased intima-media thickness and arterial stiffness can improve cardiovascular risk assessment. These sub-clinical markers aid in screening and prevention strategies for better cardiovascular health.

Area of Science:

  • Cardiovascular Medicine
  • Vascular Biology
  • Preventive Cardiology

Background:

  • Sub-clinical vascular alterations are crucial for early cardiovascular disease detection.
  • Classical risk factors alone are insufficient for comprehensive cardiovascular risk stratification.
  • Vascular markers offer insights into atherosclerosis and arterial health.

Purpose of the Study:

  • To review clinical evidence for vascular markers in cardiovascular risk stratification.
  • To highlight the importance of correct methodology for clinical application.
  • To explore the potential of vascular parameters for screening and prevention.

Main Methods:

  • Review of clinical evidence on vascular markers.
  • Focus on intima-media thickness (IMT) of the common carotid artery.
  • Assessment of arterial stiffness via carotid-femoral pulse wave velocity (PWV).
  • Evaluation of endothelial dysfunction using flow-mediated dilation (FMD) of the brachial artery.

Main Results:

  • Increased IMT is a marker of early atherosclerosis and cardiovascular disease.
  • Carotid-femoral PWV significantly improves cardiovascular risk stratification.
  • Reduced brachial artery FMD is useful in research and as a surrogate endpoint.
  • These markers can enhance risk prediction beyond traditional factors.

Conclusions:

  • Vascular markers like IMT, PWV, and FMD are valuable for cardiovascular risk stratification.
  • Standardized methodology is essential for routine clinical adoption.
  • These markers hold promise for early screening, prevention, and improved patient outcomes.

Pulse01:16

Pulse

When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...

Blood Pressure01:24

Blood Pressure

The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Blood Flow01:29

Blood Flow

Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.

Pulse amplitude and quality01:17

Pulse amplitude and quality

Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

Structure of Blood Vessels01:15

Structure of Blood Vessels

Blood is circulated throughout the human body through a network of blood vessels called the circulatory system. This system includes arteries that transport blood from the heart to various body parts. These arterial pathways divide into smaller vessels until they reach the arterioles, which further split into capillaries. It is within these minuscule capillaries that the exchange of nutrients and waste products takes place. After this exchange, the blood is collected by venules, which fuse to...
