vascular stiffness

Vascular stiffness refers to the reduced flexibility of blood vessels, making them less able to expand and contract with blood flow. Healthy blood vessels are elastic, allowing them to adapt to changes in blood pressure and volume. However, factors like aging, high blood pressure, and unhealthy lifestyles can cause the walls of the blood vessels to become stiffer. This can lead to higher blood pressure and increased strain on the heart, contributing to cardiovascular diseases. Essentially, vascular stiffness affects how well the circulatory system functions, impacting overall heart health.
