Big Data and Blood Pressure Control: Insights from the PAMELA and BP-CARE Study Cohorts

Area of Science:

• Cardiology
• Hypertension Research
• Public Health

Background:

• Effective blood pressure (BP) control remains a significant challenge in managing hypertension.
• Limited research has comprehensively assessed BP control using office, home, and ambulatory measurements and their impact on organ damage.

Purpose of the Study:

• To examine BP control patterns in the general population and treated hypertensive patients.
• To evaluate the effectiveness of different BP measurement methods (office, home, ambulatory) in assessing control.
• To investigate the relationship between BP control and organ damage, specifically left ventricular mass.

Main Methods:

• Analysis of data from two large-scale observational studies: Pressioni Arteriose Monitorate E Loro Associazioni (PAMELA) and Blood Pressure control rate and CArdiovascular Risk profilE (BP-CARE).
• Inclusion of general population data (PAMELA) and treated hypertensive patients (BP-CARE).
• Assessment of BP control via office, home, and ambulatory measurements.

Main Results:

• Only 21.1% of treated hypertensive subjects in the PAMELA study had well-controlled office BP.
• Ambulatory BP monitoring revealed more frequent control compared to home and office measurements.
• Left ventricular mass was not normalized even with adequate BP control.
• Higher cardiovascular risk in BP-CARE subjects was associated with a lower percentage of well-treated patients.

Conclusions:

• Current BP control rates, especially office-based, are suboptimal.
• Ambulatory BP monitoring provides a more accurate assessment of hypertension control.
• Achieving adequate BP control is crucial but may not be sufficient to normalize cardiac structure in hypertensive patients.
