18% on average. Meanwhile, each increase in diastolic blood pressure above 90 was tied to a 6% increase in heart disease and stroke risk.
The researchers saw a similar pattern when they looked at blood pressure increases above the 130/80 threshold. That, Flint said, supports the 2017 guideline shift.
The findings are based on over 1.3 million patients in the Kaiser Permanente health system who had roughly 36.8 million blood pressure readings taken from 2007 through 2016. Over eight years, more than 44,000 patients had a heart attack or stroke.
According to Flint, it’s the largest study of its kind to date.
The bottom line for patients, Watson said, is that they should care about both blood pressure numbers. In her
