Pulse wave velocity (PWV), also known as the cardiovascular pulse wave, is an important measure of the heart’s performance. It is a critical indicator of overall cardiovascular health, as it reflects the speed at which the blood is pumped from the heart to other parts of the body.
Pulse wave velocity is determined by measuring the time it takes for a pulse, which is the difference between the systolic and diastolic blood pressure readings, to travel between two points. Typically, these points are the carotid artery and the femoral artery.
Why Measure Pulse Wave Velocity (PWV)
Pulse wave velocity is used to assess arterial health and the degree of resistance to blood flow in the arteries. This is particularly important in evaluating and managing cardiovascular disease, such as high blood pressure and stroke.
When the PWV number is too high, it indicates that the heart is having difficulty pumping blood efficiently. This could be caused by stiffening of the arteries due to plaque build-up (atherosclerosis). On the other hand, a low PWV value indicates that the arteries are in good condition and have minimal resistance to blood flow, which is an indication of good cardiovascular health.
How to Measure Pulse Wave Velocity
Measuring PWV is relatively simple and non-invasive. To begin, a blood pressure cuff and machine are placed on the subject’s arm or leg. The cuff is then inflated and the machine measures the systolic and diastolic blood pressure at both points (inseam and carotid).
At this point, the PWV is calculated. This is done by measuring the time it takes for the pulse to reach from one point to the other, as this is a good indication of the speed at which the blood is travelling. The shorter the time, the faster the PWV. The result is then compared to the normal range to assess overall cardiovascular health.
Importance of Pulse Wave Velocity & Health
Pulse wave velocity provides important information about an individual’s general health, as it can be an early indicator of arteriosclerosis and other potential health issues. Therefore, it is important to understand and measure your PWV on a regular basis. In fact, regular checks of PWV can greatly improve your overall cardiovascular health and provide warning signs of any potential problems.
Additionally, there can be lifestyle changes that can help improve PWV. These include dietary changes, physical activity and proper stress management.
In conclusion, understanding and monitoring your PWV is a great way to keep an eye on your general cardiovascular health. By making the necessary lifestyle changes, you can help improve your PWV, reduce the risk of cardiovascular diseases, and improve your overall health.
