When your posture is off—say your spine is curved or your body isn’t balanced—areas like your arms and legs end up taking extra, uneven loads. This abnormal pressure repeatedly impacts the walls of your blood vessels, potentially causing tiny injuries. In response, your body repairs these areas by depositing extra collagen on the vessel walls. Over time, this process makes your vessels lose their natural elasticity and gradually stiffen. 📉

​

When your peripheral arteries become stiff, the blood can’t gently “massage” the vessel walls as it normally would. Instead, the pulse wave travels faster and bounces back sooner to the heart, increasing central blood pressure and pulse pressure. It’s much like water speeding through a narrowed pipe—forcing your heart to work extra hard with each beat. ❤️

Modern devices (like PASESA) assess arterial health using two key indices:

• AVI (Arterial Velocity Pulse Index)
  AVI estimates central arterial stiffness by analyzing the pulse wave shape and the timing of its reflection. When arteries are stiff (as often seen in older adults), the pulse wave falls faster and reflects earlier—resulting in a higher AVI value. More flexible arteries yield a lower AVI, directly showing the elasticity of your central vessels.

• API (Arterial Pressure Volume Index)
  API measures the stiffness of the brachial artery by looking at how the artery’s volume changes as the cuff pressure varies. Simply put, we examine the rate at which the vessel’s volume changes under pressure. A more gradual (flatter) change—reflected by a higher API value—indicates greater arterial stiffness, whereas a rapid change (steeper slope, lower API) means the artery remains more flexible. 🙌😊

 

When your body’s structure is properly balanced and forces are distributed evenly, your vessels can better maintain their natural elasticity. This promotes smooth blood flow and minimizes the impact of early pulse wave reflections on the central arteries and heart, ultimately reducing the heart’s workload. In other words, maintaining good posture and alignment helps your entire circulatory system work more harmoniously—giving your heart the protection it needs. 💪✨
