Insights

Increased blood pressure variability (BPV) is linked to higher cardiovascular risk in both men and women. This risk is particularly pronounced in men, highlighting BPV as a key indicator for cardiovascular events.

Area of Science:

  • Cardiology
  • Public Health
  • Epidemiology

Background:

  • Blood pressure variability (BPV) is a recognized prognostic indicator for cardiovascular outcomes.
  • Understanding BPV's role in cardiovascular risk is crucial for preventative strategies.

Purpose of the Study:

  • To investigate the association between within-visit blood pressure variability (BPV) and cardiovascular risk.
  • To analyze this association in participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Main Methods:

  • A cross-sectional study using baseline data from 14,357 ELSA-Brasil participants without prior cardiovascular disease.
  • Within-visit BPV quantified by coefficient of variation of three standardized systolic blood pressure measurements.
  • Cardiovascular risk assessed using the atherosclerotic cardiovascular disease (ASCVD) risk estimator and logistic regression.

Main Results:

  • Higher cardiovascular risk was significantly associated with increased BPV in both sexes.
  • Men exhibited a higher prevalence of high cardiovascular risk across all BPV quartiles compared to women.
  • Significant associations between higher BPV quartiles and increased cardiovascular risk were observed in both men and women, with a stronger effect in men.

Conclusions:

  • Within-visit blood pressure variability is associated with elevated cardiovascular risk.
  • The association between BPV and cardiovascular risk is particularly significant in men.

Assessing Blood pressure using a doppler ultrasound01:19

Assessing Blood pressure using a doppler ultrasound

To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
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.
