Blood pressure is one of the most important vital values that can be measured. High blood pressure leads to conditions that are among the top 10 diseases with the most years of life lost. Think of strokes, myocardial infarctions and heart failure. Currently, blood pressure is measured by a stand-alone, single measurement. However, blood pressure fluctuates, due to exertion, stress or the natural circadian day/night rhythm. A snapshot therefore gives a very poor representation of the actual course of a patient's blood pressure. With more than 1.4 million people in the Netherlands with high blood pressure, €6.5 billion in blood pressure-related medical costs annually, and 17.9 million deaths worldwide annually that can be related to cardiovascular diseases, there is great demand for a technology that can carry out a continuous blood pressure measurement cheaply and easily. When continuous measurement is possible, insight is obtained into the blood pressure pattern, which gives much more insight.
