How do we define HTN?

CVD risk doubles with each 20 mmHg increase systolic and 10 mmHg diastolic. Systolic BP and PP are stronger indicators of CVD than diastolic, HTN is two or more seated BP readings during each of two or more visits. Nighttime BP 10-20% lower than daytime, an attenuated BP dip may be associated with increased CVD, criteria of dx std based on 24 h blood pressure monitoring, average awake BP >135/85 and asleep BP >120/75.
