Why the study?
Most studies linking elevated blood pressure to stroke have focused on systolic blood pressure, leaving the association between diastolic blood pressure and stroke incompletely addressed.

Hypothesis-generating for DBP targets near 80 mmHg in hypertensives; prospective studies needed to clarify stroke associations.
Is diastolic blood pressure associated with a history of stroke in community hypertensive patients?
In Chinese hypertensive patients, there is a non-linear relationship between diastolic blood pressure and prior stroke, with DBP <80 mmHg associated with a lower probability of stroke.
Chen et al. (2020) studied this question.
