Why the study?
The 2017 ACC/AHA guidelines changed the definition of isolated diastolic hypertension (IDH), prompting evaluation of its prevalence and association with cardiovascular disease outcomes compared to JNC7 criteria in a Chinese population.
Is isolated diastolic hypertension defined by the 2017 ACC/AHA guidelines associated with incident cardiovascular events compared to normotension in a Chinese population?

IDH by 2017 ACC/AHA criteria was associated with higher CVD risk in Chinese adults; leaves open whether intervention alters outcomes.
Is isolated diastolic hypertension defined by the 2017 ACC/AHA guidelines associated with incident cardiovascular events compared to normotension in a Chinese population?
The 2017 ACC/AHA definition of isolated diastolic hypertension significantly increases the prevalence of IDH in a Chinese population and is associated with an increased risk of cerebral hemorrhage and total CVD.
