Heimblutdruckmessung und Wearables für die Blutdruckkontrolle
摘要
The current hypertension guidelines consistently emphasize the importance of home blood pressure monitoring. In addition to confirming the diagnosis it is possible to identify clinically relevant hypertension phenotypes. A home blood pressure reading of 135/85 mm Hg is considered the threshold for arterial hypertension. Standardized conditions must also be observed for home blood pressure measurement. By documenting the home blood pressure values measured twice in both mornings and evenings over a period of (ideally) 7 days, home blood pressure readings can be assessed quickly and easily. It is essential to ensure that a validated blood pressure monitor is used. The sensor technology built into “smart technologies” allows cuffless detection of (pulse) waveforms and thus estimation of blood pressure. Validation based on a specific protocol is not necessary. Possible sources of error include bias, deviations over time and (varying) environmental conditions. For this reason, cuffless blood pressure measurement is not recommended by current hypertension guidelines. The Apple Watch takes a different approach: instead of blood pressure values it displays the message “possible hypertension.” Due to its widespread use we will probably be confronted increasingly more with this issue but greater awareness and more newly diagnosed hypertensive patients can also be expected.
