Surprising Findings
Cumulative BP improved prediction even with only three measurements over six years.
Most assume you need frequent, long-term monitoring to calculate 'cumulative exposure,' but this study shows even sparse data can add value.
Practical Takeaways
Track your blood pressure over time, not just at annual checkups—use home monitors and keep a log.

For people living in rural China, having higher average diastolic blood pressure over time is linked to a higher chance of heart disease — even if you already account for their starting blood pressure and other health factors.
In rural China, adults who have had the highest blood pressure levels over time are much more likely to get heart disease than those with the lowest levels — and the higher the pressure, the greater the risk.
For people in rural China, tracking blood pressure over time gives a better warning about future heart problems than just one early reading—and the more your average pressure adds up over the years, the higher your risk.
For rural Chinese adults, using a person's average blood pressure over time instead of just one early reading slightly improves heart disease risk predictions — but it’s not a game-changer.
Even in older adults, high blood pressure over time still raises the risk of heart problems — but the effect is strongest in younger people. This means keeping blood pressure in check matters at every age, especially in rural China.
