Arterial stiffness refers to the loss of elasticity in the arteries, which play a crucial role in the cardiovascular system by allowing blood to flow smoothly and efficiently throughout the body. When arteries become stiff, they can no longer expand and contract as easily, leading to increased blood pressure and potential damage to the heart and other organs. Research in arterial stiffness often focuses on identifying risk factors and mechanisms that contribute to this condition, as well as developing methods for early detection and treatment. Arterial stiffness is associated with aging, high blood pressure, diabetes, and other cardiovascular risk factors, making it an important area of study for preventing and managing cardiovascular diseases. Several techniques are used to measure arterial stiffness, including pulse wave velocity and augmentation index, which can provide valuable information about an individual's cardiovascular health. By understanding and addressing arterial stiffness, researchers aim to improve overall cardiovascular health and reduce the risk of heart disease and other related conditions.
