[2025-09-25T11:09:30.509817] [PI reasoning] **Exploring heart rate and aortic stiffness**

I’m considering the question about whether acute changes in heart rate from isoproterenol impact aortic stiffness in hypertensive patients. It appears they used an intravenous method to elevate heart rate and then measured aortic stiffness through pulse wave velocity. I remember studies indicating that acute heart rate increases don’t significantly alter aortic stiffness for hypertensive patients. Generally, it seems heart rate has limited independent effects, while blood pressure plays a more crucial role.
