Now, as a doctor who does this every day, do you ever worry about pushing blood pressure too low for your patients?

The new guidelines around 130 have been shown to be very safe across many trials, and that's true across a broad range of patients, including our older and more frail patients.

We have trials that have specifically looked at those patients, specifically looked at patients over 70, over 80, across different populations in North America, as well as East Asia.

And it shows broadly that those more aggressive targets actually save lives with very little risk.

Of course, there isn't no risk, and we do have to monitor these patients closely.

In the trials, patients would have been monitored regularly with very close follow-up and carefully measured blood pressure with careful attention to side effects.

And I think we need to replicate that as best we can.

I've heard that potassium works almost the opposite way that sodium does, actually helping lower the blood pressure.
