Some cursory googling leads to recent research showing that they do: "According to new research, both high systolic and high diastolic blood pressure can lead to heart attack and stroke." [1]
> HRV results
I feel there is hype over HRV. Mainly a new thing that watches and other monitors can measure, and the number is being hyped. That put aside, the sources I've listened to have concluded that HRV is not really that valuable. Do you know of research showing otherwise? (grant it, some research is good here, for most things medecine and science there needs to be a lot of research. My impression there is a lot of research around blood pressure, thus I am not digging out more sources to show the counter-point).
