Clinical Benefits of Consistent Reduction in the Daily Blood Pressure of Hypertensive Patients
Key result
Antihypertensive therapy should target dynamic BP control to lower both overall levels and variability.
Why the study?
Mean 24-hour BP values and BP variability are more closely associated with cardiovascular events and organ damage than clinic measurements, highlighting the need to assess dynamic BP control in antihypertensive therapy.
Does consistent reduction in daily blood pressure and blood pressure variability improve cardiovascular outcomes in hypertensive patients?

Implication
ABPM parameters beyond mean 24-hour BP may refine risk stratification; hypothesis-generating for outcome trials targeting variability.
Key Points
- To examine the prognostic value of 24-hour ambulatory blood pressure and blood pressure variability in managing hypertension and mitigating cardiovascular risk.
- Synthesized findings comparing 24-hour ambulatory blood pressure monitoring with conventional clinic blood pressure measurements.
- Evaluated the clinical impacts of daytime and nighttime blood pressure levels alongside blood pressure variability on target organ damage and cardiovascular outcomes.
- Mean 24-hour, daytime, and nighttime blood pressure levels correlate more strongly with target organ damage and cardiovascular events than single clinic measurements.
- Elevated blood pressure variability independently associates with increased organ damage and cardiovascular event risk, which can be aggravated by medications with waning efficacy over time.
- Effective antihypertensive strategies require dynamic control that simultaneously lowers absolute blood pressure levels and minimizes blood pressure variability throughout the day.

Population
Hypertensive patients
I
Intervention
Antihypertensive therapy aiming for dynamic control of blood pressure (lower BP and lower BP variability)
O
Outcome
Cardiovascular events and target organ damage
Ambulatory blood pressure monitoring and dynamic control of both blood pressure and its variability are crucial for reducing cardiovascular risk in hypertensive patients.

Giuseppe Mancia (2002) conducted a review in Hypertension. Antihypertensive therapy was evaluated. Dynamic control of blood pressure, including lower overall blood pressure and reduced blood pressure variability, should be the primary aim of antihypertensive therapy.
