Insights
High long-term systolic blood pressure variability is linked to silent brain lesions in hypertensive patients. This association is partly explained by elevated blood pressure levels.
Area of Science:
- Cardiology
- Neurology
- Hypertension Research
Background:
- Blood pressure (BP) variability is a significant predictor of target organ damage and cardiovascular outcomes.
- Silent cerebral white matter lesions are markers of subclinical brain damage in hypertensive individuals.
Purpose of the Study:
- To investigate the association between blood pressure variability and silent cerebral white matter lesions.
- To analyze this relationship in middle-aged, asymptomatic essential hypertensive patients.
Main Methods:
- Studied 43 untreated middle-aged hypertensive patients.
- Assessed short-term and long-term BP variability using continuous beat-to-beat and ambulatory monitoring.
- Utilized cerebral MRI to detect white matter lesions.
Main Results:
- Patients with white matter lesions showed higher long-term systolic BP variability (P=0.047 and P=0.022).
- This association was not independent of elevated BP and lost significance after adjustment.
- No significant differences were found for short-term systolic or any diastolic BP variability.
Conclusions:
- Long-term systolic BP variability is significantly associated with silent cerebral white matter lesions in essential hypertensives.
- The relationship is partially dependent on the absolute level of blood pressure elevation.
Background:
It is recognized that blood pressure (BP) variability has prognostic significance in determining target organ damage and cardiovascular mortality and morbidity. The aim of this study was to analyze the association between blood pressure variability and the presence of silent cerebral white matter lesions in middle-aged asymptomatic essential hypertensives.
Methods:
We studied 43 middle-aged untreated hypertensive patients. Blood pressure variabilities (short-term and long-term) were evaluated by using both non-invasive, beat-to-beat, continuous finger 24-hour monitoring (Portapres) and oscillometric automated discontinuous ambulatory blood pressure monitoring. All patients underwent cerebral magnetic resonance imaging to detect the presence or not of white matter lesions.
Results:
Hypertensive patients with cerebral white matter lesions exhibited significantly higher values of long-term systolic blood pressure variability (standard deviation of 24-hour blood pressure) measured both by continuous beat-to-beat monitoring (16.2 +/- 3.7 v 13.7 +/- 3.6 mm Hg; P = 0.047) and by ambulatory blood pressure monitoring (15.2 +/- 3.8 v 12.8 +/- 2.7 mm Hg; P = 0.022). However, these differences were not independent on blood pressure elevation and did not maintain their significance after adjusting for 24-hour systolic blood pressure. Neither short-term systolic blood pressure variability, nor short-term or long-term diastolic blood pressure variabilities showed differences between patients with and without white matter lesions.
Conclusion:
The present study indicates that long-term systolic blood pressure variability is significantly related to the presence of silent cerebral white matter lesions in essential hypertensive patients, although this relationship is partially dependent on absolute blood pressure elevation.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...
