Question 1

What is the Meaning of Vascular Compliance?

Accepted Answer

Vascular compliance refers to the intrinsic ability of a blood vessel, particularly an artery, to distend and accommodate an increase in blood volume in response to changes in transmural pressure.

Question 2

What is the Context of Vascular Compliance?

Accepted Answer

This physiological characteristic is fundamental to the efficient operation of the cardiovascular system, serving to buffer the pulsatile flow of blood ejected from the heart into the arterial tree, thereby stabilizing peripheral blood pressure.

Question 3

What is the Significance of Vascular Compliance?

Accepted Answer

Understanding vascular compliance is crucial in clinical assessment, as it directly influences cardiac workload, pulse pressure, and peripheral tissue perfusion, providing insights into overall cardiovascular health.

Question 4

What is the Mechanism of Vascular Compliance?

Accepted Answer

The mechanical properties of the vessel wall, primarily the ratio of elastic to collagen fibers and the state of vascular smooth muscle tone, dictate its compliance; elastic fibers stretch to store energy during systole and recoil during diastole.

Question 5

What is the Application of Vascular Compliance?

Accepted Answer

Clinicians frequently consider vascular compliance when evaluating cardiovascular risk, as diminished compliance, or arterial stiffness, is a key indicator for the progression of vascular disease and a target for therapeutic interventions.

Question 6

What is the Metric of Vascular Compliance?

Accepted Answer

Non-invasive methods such as pulse wave velocity (PWV) are routinely employed to quantify arterial stiffness, offering a practical and accessible assessment of vascular compliance, while augmentation index also provides relevant data.

Question 7

What is the Risk of Vascular Compliance?

Accepted Answer

Reduced vascular compliance significantly elevates the risk for various adverse cardiovascular outcomes, including hypertension, coronary artery disease, stroke, and heart failure, reflecting a compromised ability of the vessels to effectively manage blood pressure fluctuations.
